Description

Self-adaptive sterilization intensity regulation and control method and device and electronic equipment

Technical Field

The invention relates to the technical field of aquaculture and informatization, in particular to a self-adaptive sterilization intensity regulation and control method and device and electronic equipment.

Background

The aquatic water environment directly carries the life and growth of the aquatic products, whether the aquatic products are good or not directly influences the health degree and the production efficiency of the aquatic products, and in order to keep the health state of the aquatic products, a sterilization technology is often needed to control the concentration of active pathogenic microorganisms in the water environment. The existing method is to recycle the aquaculture water after complete sterilization so as to reduce the risk of disease occurrence. However, the method has the defects that firstly, the method is not suitable for open water cultivation scenes with background active pathogenic microorganism concentration such as large water surfaces, ocean pastures and the like. Secondly, the existing method ignores the establishment and the effect of the autoimmune barrier of the cultured aquatic products. Finally, the existing method ignores dynamic balance among beneficial microorganism colonies in water environment, especially nitrifying bacteria, and the full-power sterilization operation can cause unbalance of beneficial bacterial groups of the water body, and the recovery time after unbalance is longer, so that the health of internal environments such as intestinal tracts of cultured aquatic products is influenced.

In the running of cultivation facilities such as factory cultivation, fish and vegetable symbiotic systems and the like, equipment such as a circulating water pump, a sterilizing and filtering device and the like are main sources of energy consumption in the cultivation process. If the system runs at full load or constant power throughout the day, the energy consumption is quite high, so that the economic benefit of farmers is greatly reduced. At present, physical sterilization and bacteria reduction technologies such as ultraviolet rays, filtration, electrostatic adsorption, heating sterilization, ionizing radiation and the like are often combined and applied to microbial sterilization and disease prevention and control of a aquaculture water environment, and energy conservation, consumption reduction and environmental protection are mainly focused on the realization of energy conservation, consumption reduction and the like in a mode of improving the efficiency of functional devices. For example, CN114600821B discloses an energy-saving method using multiple treatment modes in time-sharing mode, which uses the huge difference of water before and after feeding, day and night and before and after water treatment to perform time-sharing treatment in different modes, and also operates under full load in sterilization link. In addition, according to the ultraviolet dose-inactivation rate curve, the irradiation dose required for total inactivation is maximum, the energy consumption is maximum, and the sterilization device and the water circulation power in the sterilization link generally keep running continuously after fixed starting, and the adjustment of the sterilization intensity change is not considered. The analysis shows that the method still has unique advantages and innovative development space in the aspects of sterilization intensity, control time sequence and the like.

In view of the above problems, the existing method for killing pathogenic microorganisms in the aquaculture water environment cannot adapt to the development target of green cleaning, and a more scientific and reasonable sterilization intensity regulation method with strong pertinence is needed.

The self-adaptive sterilization intensity regulating method provided by the embodiment of the invention introduces the concept of maximum pathogenic microorganism tolerance concentration which changes along with water environment parameters, and realizes the control of the expansion of the sterilization process in the time dimension, namely the conversion from constant power (intensity) sterilization or periodic switch sterilization to intermittent variable power (intensity) sterilization when the self-adaptation of the aquaculture water environment is shorter, because the existing sterilization process control mainly runs with full power. The method provides possibility for saving power consumption by dynamically adjusting and reducing the concentration killing amount of pathogenic microorganisms in unit time, optimizes the sterilization intensity and control time sequence in the sterilization process, and realizes the stable control of repeated cycle intermittent sterilization.

The method has the advantages that the method is used for implementing variable-intensity sterilization by utilizing the maximum tolerance concentration value of pathogenic microorganisms which changes along with water quality parameters, and combines an automatic control technology, so that the sterilization accuracy is improved, and the damage to the flora environment of the aquaculture water body is reduced, aiming at the problems that sterilization is frequent, the sterilization time length and the automation degree of intensity control are low, the balance of beneficial bacterial colonies of the aquaculture water environment is damaged due to the fact that the sterilization dosage exceeds the standard, and the like in the water use process of aquaculture.

The embodiment of the invention describes an adaptive sterilization intensity control method by taking an adaptive sterilization intensity control device as an execution main body as an example.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic flow chart of the adaptive sterilization intensity control method according to the present invention, and fig. 2 is a second schematic flow chart of the adaptive sterilization intensity control method according to the present invention.

As shown in fig. 1, the method comprises the following steps:

Step S110, acquiring a plurality of water quality index parameters of the aquaculture water environment in a preset time period and an actual concentration value of target pathogenic microorganisms at the current moment;

Step S120, determining a maximum bearing concentration value of the target pathogenic microorganism based on an immune balance equation of the target pathogenic microorganism to the target aquatic product in the environment of the plurality of water quality index parameters within the preset time period;

Step S130, determining the concentration killing amount of the target pathogenic microorganism based on a preset safe concentration threshold value, the maximum bearing concentration value and the actual concentration value of the target pathogenic microorganism;

Step S140, based on the concentration killing amount, dynamically regulating and controlling sterilization process parameters in a grading manner, and sterilizing the aquaculture water environment;

and step S150, repeating the steps S110-S140 to finish the self-adaptive sterilization process.

The method generates maximum bearable pathogen concentration for sterilization strength grading adjustment through the infection dynamic balance between pathogenic microorganism and target aquatic product which change along with water quality, and the technical principle is that the infection force which changes along with water quality condition is controlled at the inner side of a dynamic balance equation, so that the health of the aquatic product can be maintained.

As shown in fig. 2, the flow for one embodiment is described as follows:

specifically, the self-adaptive sterilization intensity regulating device determines a aquaculture water environment needing sterilization intensity regulation, acquires target aquatic product information and target pathogenic microorganism information in the aquaculture water environment, determines various constant index values in an infectivity balance equation, and generates subsequent maximum tolerance concentration and concentration killing amount based on the equation.

Based on step 110, the adaptive sterilization intensity control device obtains the water quality index parameters of the aquaculture water environment within a preset time period, wherein the preset time period is set by experience according to actual conditions, such as 1h, 10min and 5min.

It should be noted that, the water quality space formed by a plurality of water quality indexes and the values of the plurality of water quality indexes in the aquaculture water environment is called a water quality parameter space, and the plurality of water quality indexes include, but are not limited to, water temperature, PH value, dissolved oxygen, nitrate, illumination condition and turbidity. In an embodiment, the water quality parameter space may be expressed in aggregate as W _φ =w (x, y, z.), x, y, z.,. Epsilon.r+, and in order to ensure the survival rate and quality of the cultured aquatic products, the parameter values corresponding to the water quality indexes should be within the suitable survival range of the target aquatic products. Wherein x, y and z are selected main water quality indexes, W _ijk… is adopted to represent a water quality parameter space with water quality index parameters of x _i, y_j, z_k, i, j, k is less than or equal to n, and n is a positive integer.

Therefore, the water quality parameter vector of the aquaculture water environment in the preset time period is composed of a plurality of water quality index parameters in the preset time period, the water quality index parameters can be obtained by measuring the water quality index, and the water quality parameter space is mainly used for simply representing the water quality index parameters.

Meanwhile, the self-adaptive sterilization intensity regulating device also needs to acquire the actual concentration value of the target pathogenic microorganism at the current moment.

Based on step 120, the adaptive sterilization intensity control device determines an immune balance equation of the target pathogenic microorganism to the target aquatic product in the water quality parameter space in the preset time period based on the water quality parameter space of the aquaculture water environment in the preset time period, namely based on a plurality of water quality index parameters of the aquaculture water environment in the preset time period.

Further, the self-adaptive sterilization intensity regulating device determines the moment when the target pathogenic microorganism has immune balance on the target aquatic product in the current water quality parameter space and the concentration value corresponding to the existence of the immune balance, namely the maximum bearing concentration value, based on a plurality of water quality index parameters in the current water quality parameter space.

Based on step 130, the adaptive sterilization intensity control device determines a concentration killing amount between an actual concentration value of the target pathogenic microorganism and an actual concentration control target value based on a maximum sustained concentration value, a specific preset safe concentration threshold value thereof, and an actual concentration value thereof when the target pathogenic microorganism has an immune balance on the target aquatic product.

Based on step 140, further, the adaptive sterilization intensity control device determines a sterilization intensity level required for the sterilization process based on the concentration killing amount.

If the task of the concentration killing amount is not completed at the current moment, the intermittent sterilization treatment is continued to be carried out for fixing the sterilization period T, and then whether the task of the concentration killing amount in the period is completed is judged.

If the control period is not finished, the self-adaptive sterilization intensity regulating device returns to the first step, and the steps 110-140 are repeated, namely, the water quality parameter space of the aquaculture water environment in a preset period and the actual concentration value of the target pathogenic microorganisms at the current moment are obtained, and the sterilization intensity regulating process is continuously executed, so that the healthy dynamic management in the aquaculture process is realized.

According to the self-adaptive sterilization intensity regulation method provided by the invention, dynamic balance of the infection process of target pathogenic microorganisms and target aquatic products along with the change of water quality is considered, an immune balance equation of the target pathogenic microorganisms on the target aquatic products under the water quality of a certain water body environment is introduced, the maximum bearing concentration value of the target pathogenic microorganisms is determined, the concentration killing amount of the target pathogenic microorganisms is determined according to a preset safe concentration threshold value, the maximum bearing concentration value and an actual concentration value, sterilization process parameters are dynamically regulated and controlled in a grading manner based on the concentration killing amount, the aquaculture water environment is sterilized, the self-adaptability, pertinence and the process of sterilization regulation are improved, the energy consumption is saved, and the self-adaptive sterilization intensity regulation method is green, efficient, scientific and reasonable. In addition, when the tolerance of the target aquatic product to the target pathogenic microorganisms is higher in the water quality of a certain water body environment, the sterilization intensity can be adaptively and properly reduced, and sterilization and disinfection are only needed when the tolerance of the target aquatic product to the target pathogenic microorganisms is reduced due to the water body environment and the infection process is deteriorated, so that the influence of the autoimmune system of the target aquatic product and the water body environment on the pathogen infection activity is utilized to the greatest extent, and the sterilization intensity and the energy consumption of the water body are further effectively reduced.

Further, according to S1203, the adaptive sterilization intensity control device determines an immune balance equation of the target pathogenic microorganism on the target aquatic product in the environment of a plurality of water quality index parameters within a preset time period based on the infection activity and the anti-infection capability.

In one embodiment, the equation of the immune balance of the target pathogenic microorganism to the target aquatic product over the predetermined period of time is as follows:

It should be noted that, in an embodiment, if two or more pathogenic microorganisms are to be killed, the concentration killing amounts of the multiple pathogenic microorganisms are added up to multiply by the correction coefficient to achieve a synergistic effect, specifically: . Wherein, Is the sum of the concentration killing amount of m pathogenic microorganisms; representing a correction factor, generally greater than 1, which can be set to 1.2, which is adjusted according to the synergistic effect of actual multiple diseases, determined by empirical values; indicating the equivalent concentration kill of the population of the plurality of pathogenic microorganisms.

According to the embodiment of the invention, based on an immune balance equation under the condition of immune balance between the target pathogenic microorganisms and the target aquatic products, the concentration killing amount of the target pathogenic microorganisms is determined, and then the sterilization intensity of the aquaculture water environment is regulated and controlled based on the concentration killing amount, so that the dynamic sterilization intensity regulation and control based on the self-adaptability of the aquaculture water environment are realized, the sterilization intensity regulation which is dynamically balanced and varies with the water quality through pathogen infection can effectively save energy consumption, and the reasonable and targeted sterilization of the aquaculture water environment is realized.

In some embodiments, based on the content developed in step S140, based on the concentration killing amount, the sterilization intensity of the aquaculture water environment is regulated, and the specific content of the process includes:

s141, if the concentration killing amount is larger than zero, determining a sterilization intensity level based on the concentration killing amount and the preset safety concentration threshold;

s142, determining sterilization power and water inflow under different sterilization intensity levels based on a function between the inactivation rate y and the ultraviolet dose x;

S143, dynamically sterilizing the aquaculture water environment based on the sterilization power and the water inlet speed under the different sterilization intensity levels.

It should be noted that the function of the uv dose x and the inactivation rate y in this step is pre-constructed based on the uv dose-inactivation rate curve. Taking ultraviolet water disinfection equipment as an example, the specific steps are as follows:

first, a characteristic curve of the verification dose is constructed. The parameters which can be adjusted by the ultraviolet disinfection equipment are specified in the standard ultraviolet dose test method of ultraviolet water disinfection equipment (GB/T32091-2015) and comprise the water flow Q and the output power P of an ultraviolet lamp tube. The verification dosage of the ultraviolet water disinfection equipment is related to factors such as ultraviolet transmittance, ultraviolet light intensity, flow, lamp tube number and the like of a water body, and a a, b, c, d, e constant is calculated by a linear regression method according to experimental data of the dosage test of the disinfection equipment and the formula RED= ^a×A₂₅₄ ^b×P^c×Q^d×B^e, so that a characteristic curve of the ultraviolet water disinfection equipment can be obtained. Wherein RED represents the verification dosage of the ultraviolet water disinfection device, A ₂₅₄ represents the absorbance of water UV ₂₅₄, P represents the output power of the ultraviolet water disinfection device, Q represents the corresponding flow of the device, B represents the number of ultraviolet module units (only for canal type disinfection device, the item of pipe type disinfection device is 1), and a, B, c, d, e is a constant. It will be appreciated that RED represents an equation constrained by P and Q. The water quality influence a ₂₅₄ is mainly the influence of the turbidity of the water body, specifically, the absorbance of UV ₂₅₄ =1-ultraviolet transmittance UVT, and the ultraviolet transmittance UVT is influenced by the water quality parameters. Thus, this effect is also taken into account in the acquired water quality parameters. The effect of the validation dose on equipment fouling and aging is referred to as the effective validation dose, and there is no specific distinction between the two in this example, and is described in detail in the standard. In addition, in the present embodiment, the verification dose RED is equivalent to the actual ultraviolet dose x.

Further, a function between the ultraviolet dose x and the inactivation rate y is constructed based on the ultraviolet dose-inactivation rate curve. Because the inactivation rate is affected by the ultraviolet dose, in order to dynamically adjust the ultraviolet dose according to the inactivation rate and explain the regulation relation of two parameter values of the sterilization power P and the inflow water flow Q in the water quality regulation and control process, according to the ultraviolet dose-inactivation rate curve described in the standard, a function of the ultraviolet dose x and the inactivation rate y is constructed and is marked as y=f (x) (x epsilon A, A is more than or equal to 0), the value range of the function is 0-100%, and the inverse function of the function can be correspondingly obtained and can be expressed as x=f ^-1 (y) =RED. The relation equation of two regulating variables of the inactivation rate y, the sterilization power P and the inflow water flow Q is that y=f (P, Q) =f (10 ^a×A₂₅₄ ^b×P^c×Q^d)), and the relation equation is taken as the basis for regulating and controlling two parameter values of the sterilization power P and the inflow water flow Q in the water quality regulating and controlling process, wherein the inactivation rate, namely the sterilization rate used in the embodiment, represents the ratio of the concentration sterilization amount to the initial concentration, is different from the sterilization logarithmic value, wherein the sterilization rate= [1-10 (sterilization logarithmic value) ]multipliedby 100 percent.

Before proceeding to step 140, the actual concentration killing amount value is determined. If the actual concentration killing amount of the target pathogenic microorganism is larger than zero, the self-adaptive sterilization intensity regulating device determines the sterilization intensity level based on the magnitude relation between the concentration killing amount and a preset safety concentration threshold value. This step is developed in the event that the actual concentration kill of the target pathogenic microorganism is greater than zero.

For the determination of the sterilization intensity level based on the concentration killing amount and the preset safety concentration threshold in the step S141, the specific content of the process includes:

In particular, if the concentration of the target pathogenic microorganism is at a killing level(Or equivalent concentration kill amount)) The self-adaptive sterilization intensity regulating device determines that the sterilization intensity level is the first sterilization intensity level when the self-adaptive sterilization intensity regulating device is larger than a preset safety concentration threshold value of a first preset multiple, wherein the first preset multiple can be set to be 1 time according to actual conditions, and the concentration killing amount is larger than the preset safety concentration threshold value c ₀.

Further, if the concentration of the target pathogenic microorganism is a killing amount(Or equivalent concentration kill amount)) The self-adaptive sterilization intensity regulating device determines that the sterilization intensity level is a secondary sterilization intensity level, wherein the second preset time is set according to actual conditions, can be set to 0.5 time, and the 0.5 time preset safety concentration threshold c ₀ < concentration sterilization amount < preset safety concentration threshold c ₀ is higher, and in the case, the water quality change is not great, and the infection force balance change caused by the water quality change can be kept in a controllable range by adopting normal sterilization intensity.

Further, if the concentration of the target pathogenic microorganism is a killing amount(Or equivalent concentration kill amount)) The self-adaptive sterilization intensity regulating device determines that the sterilization intensity level is three-level sterilization intensity level when the concentration killing amount is smaller than a preset safety concentration threshold value of a second preset multiple, namely a preset safety concentration threshold value c ₀ of the second preset multiple, wherein if the second preset multiple is set to be 0.5 time, the preset safety concentration threshold value c ₀ of the concentration killing amount is smaller than 0.5 time, and under the condition, the water quality change is considered to be smaller, the sterilization intensity can be reduced, and the infection force balance change caused by the water quality change is kept in a controllable range.

The sterilization power and inflow rate at different sterilization intensity levels are determined for the function based on the inactivation rate y and the ultraviolet dose x described in step S142 above.

In this embodiment, the adaptive sterilization intensity control device is correspondingly classified into three levels based on the functions of the ultraviolet dose x and the inactivation rate y, and the first sterilization power and the first water inlet flow of the first level sterilization intensity level, the second sterilization power and the second water inlet flow of the second level sterilization intensity level, and the third sterilization power and the third water inlet flow of the third level sterilization intensity level are correspondingly and sequentially determined. Optionally, the second sterilizing power may be considered to be half of the standard power in the prior art, and the water inlet flow rate regulating value is half of the water inlet speed normally set by the water pump.

It should be noted that, the function of the inactivation rate y and the ultraviolet dose x, that is, based on the inactivation rate y, the sterilization power P, and the equation of the inflow water flow Q, the inactivation rate y is constrained by the sterilization power P and the inflow water flow Q, that is, x=f ^-1(y) =RED=10^a×A₂₅₄ ^b×P^c×Q^d. Therefore, the different inactivation rates y correspond to the combinations of the sterilization power P and the inflow water flow Q, and can be classified into more levels according to the functions of the inactivation rates y and the ultraviolet dose x, but in this example, the inactivation rates y and the ultraviolet dose x are only classified into three groups.

Specifically, if the sterilization intensity level is the primary sterilization intensity level, sequentially determining a first sterilization power and a first water inflow rate according to a function of the inactivation rate y and the ultraviolet dose x, and respectively using a corresponding power value corresponding to increased sterilization irradiation and a corresponding water inflow rate value of a reduced water pump as the first sterilization power and the first water inflow rate;

it should be noted that in this step, the value of the inflow rate may be determined first, and then the corresponding sterilizing power P may be determined.

Aiming at the dynamic sterilization of the aquaculture water environment based on the sterilization power and the water inflow speed under the different sterilization intensity levels in the step 143, the following steps are executed for the regulation and control of the sterilization power and the water inflow flow:

Further, the self-adaptive sterilization intensity regulating device regulates and controls adjustable parameters of the sterilizing equipment in a grading manner according to three levels of sterilization power and inflow water flow determined by different sterilization intensity levels, wherein the adjustable parameters comprise sterilization power P and inflow water flow Q, and dynamically sterilizes the aquaculture water environment. Wherein, the sterilization power P and the water inflow rate Q are reflected on the quantity of ultraviolet lamp tubes and the adjustment of the water inflow speed of the water pump.

Specifically, if the sterilization intensity level is a primary sterilization intensity level, the self-adaptive sterilization intensity regulating device performs sterilization on the aquaculture water environment according to the first sterilization power and the first water inflow, namely by adopting regulating measures of increasing sterilization irradiation amount and reducing water inflow speed of the water pump. In one embodiment, the increase of the original sterilization irradiation amount can use the arrangement of a plurality of ultraviolet lamp tubes to enhance the upper limit of the intensity regulation of the sterilization irradiation amount.

In another case, if the sterilization intensity level is a secondary sterilization intensity level, the self-adaptive sterilization intensity regulating device performs sterilization on the aquaculture water environment according to the second sterilization power and the second water inflow rate, namely using the normal sterilization irradiation amount and the normal water inflow rate.

In another case, if the sterilization intensity level is a three-level sterilization intensity level, the self-adaptive sterilization intensity regulating device performs sterilization on the aquaculture water environment according to the third sterilization power and the second water inflow rate, namely, by adopting the radiation amount of halving sterilization and improving the water inflow speed of the water pump. In one embodiment, halving the original germicidal irradiation level may employ halving the use of ultraviolet lamps or power adjustment to reduce the germicidal irradiation level intensity.

Based on step S150, in the flow described in fig. 2, steps S110 to S140 are repeated to complete the adaptive sterilization process. Specifically, if the concentration killing amount of the target pathogenic microorganism is less than or equal to zero, the self-adaptive sterilization intensity regulating device judges whether the prevention and control period is finished.

Further, if the prevention and control period is over, the self-adaptive sterilization intensity regulating device ends the sterilization intensity regulating process, and if the prevention and control period is not over, the self-adaptive sterilization intensity regulating device returns to the first step, and the steps 110-140 are repeated, so that the water quality parameter space of the aquaculture water environment in the preset period and the actual concentration value of the target pathogenic microorganisms at the current moment are obtained, the sterilization intensity regulating process is continuously executed, and the healthy dynamic management in the aquaculture process is realized.

In summary, the embodiment of the invention combines the flow of an embodiment shown in fig. 2, and describes that different sterilization intensity selections are executed according to concentration sterilization amount, so that the sterilization intensity is regulated and controlled in a grading manner, the sterilization irradiation amount is further controlled dynamically, the sterilization process is refined in an energy-saving manner, and the accurate quantitative energy consumption control is realized, thereby realizing the reasonable and targeted sterilization of the aquaculture water environment.

It should be noted that, when the adaptive sterilization intensity control device provided by the present invention is specifically operated, the adaptive sterilization intensity control method described in any one of the above embodiments may be executed, and this embodiment will not be described in detail.

In addition, the self-adaptive sterilization intensity regulating device has two typical application forms. The device is used as an independent device for integrated use, such as in relatively independent closed water bodies of traditional pond culture and the like, sterilization intensity control based on the water body environment is realized through in-situ deployment of the device, and the device is used as a dispersion mode, such as in open/semi-open scenes of semi-open industrial culture, culture engineering and the like, and can be dispersed into other facility equipment to be matched with other equipment through main components.

Specifically, in an embodiment, for the closed application scenarios such as in-water circulation and traditional pit culture in facility culture such as factory, because the water treatment capacity is relatively fixed, an in-situ sterilization treatment device in an independent form is used in the scenario, and sterilization regulation and control are performed according to the internal water quality index parameters of the device. According to the method, the device dynamically monitors the water quality change and the immune balance of the concentration of pathogenic microorganisms to realize the control of the concentration of the pathogenic microorganisms so as to reduce the occurrence of diseases.

Specifically, in another embodiment, the method is used in an open/semi-open application scenario in which the water quality index parameter is inconvenient to adjust and the concentration of the water quality index parameter and the target pathogenic microorganism is in a relatively fixed large water surface containment mode, a deep sea net cage, a work ship and the like, and the culture is performed by using environmental water. Because the water quality index parameters are difficult to control, the concentration of the target pathogenic microorganisms in the water body needs to be adjusted at the water inlet according to the water quality conditions in the cultivation facilities. In this scenario, the background concentration of pathogenic microorganisms is the biggest influencing factor for disease occurrence, especially in situations where insufficient energy supply or complete killing is not feasible, whereas traditional complete killing consumes huge energy. The reasonable pathogen concentration is particularly important based on water quality reduction, so that energy consumption can be saved, and the disease prevention effect generated by unit energy consumption can be improved. It will be appreciated that at this point the body of water is divided into an inner and an outer portion, the outer body of water is defined as a first body of water, the inner body of water is defined as a second body of water, the actual concentration of the target pathogenic microorganism can be determined in the first body of water, and the water quality index parameter can be determined in the second body of water. The water body in the water inlet process is treated by the rapid sterilization mode formed by the device to construct a barrier, the second water area has a large culture density, and the internal and external environments have tiny but obvious water quality index parameter differences, so that the tolerance of the target aquatic product to the target pathogenic microorganism is reduced, and the sterilization treatment is required according to the water quality parameters of the second water body.
