It should be noted that, in order to describe the present specification in more detail so as to enable those skilled in the art to understand the present specification more clearly and clearly, and to support the technical problems to be solved and the technical effects to be achieved by the present specification, before describing the present specification, the following explanations are made for terms and terms related thereto:

the unit area refers to an area with sewage, such as a residential area, a school, an office building, a shopping mall and the like; the sewage branch pipe, the 'confluence pipe', is a pipeline used for conveying rainwater, sewage or mixed water of the rainwater and the sewage in the unit area pipeline; the 'accommodating area' is used for collecting and chemically treating the sewage transmitted by the sewage branch pipes in the unit area and can be a tank body structure with a treatment function similar to a septic tank and the like; "bottom elevation" refers to the elevation value of the bottommost layer of a component at a certain location.

When the sewage storage and regulation device provided by the embodiment of the specification is applied to a specific application scene of a drainage system, the sewage storage and regulation of the sewage, namely the discharge and storage of the sewage, can be realized by the sewage storage and regulation device based on the air pressure input by a vacuum pump and the self gravity of the sewage, and the drainage system can comprise a sewage branch pipe, a containing area 20, a confluence pipe 30, a municipal pipeline and the like, wherein the sewage branch pipe is connected with the containing area so as to intensively convey the sewage in the unit area to the containing area.

Example one

Specifically, referring to fig. 1-3, in the embodiment of the sewage storage device, the sewage storage device at least includes a flow dividing region 10, a storage region 40 and a vacuum pump 130.

Wherein, the shunting area 10 is internally provided with a shunting space 101 which can be used for containing sewage and is respectively communicated with the containing area 20 and the confluence pipe 30; the size and volume of the flow dividing space 101 are not limited in the present invention, and can be flexibly designed according to actual operation requirements. Similarly, the storage area 40 also has a storage space 401 for storing the above-mentioned sewage therein, and is communicated with the flow dividing area 10; the size and volume of the storage space 401 are not limited in the present invention, and may be flexibly designed according to actual operation requirements. The shunting area 10 is internally provided with a shunting space 101 for containing sewage and is respectively communicated with the containing area and the confluence pipe; the bottom elevation of the part of the storage area 40 communicated with the shunt area 10 is lower than the bottom elevation of the part of the shunt area 10 communicated with the confluence pipe 30; here, the portion where the storage region 40 communicates with the flow dividing region 10 may refer to a portion where the sewage is supplied from the storage region 40 to the flow dividing region 10 or the sewage is supplied from the flow dividing region 10 to the storage region 40. The vacuum pump 130 is a device for pumping gas in the storage region 40 to form a vacuum tight chamber in the storage region 40, thereby forming a gas pressure difference between the flow dividing region 10 and the storage region 40.

When the storage area 40 needs to be filled with water, the vacuum pump 130 pumps the gas in the storage area 40 to form a vacuum tight chamber in the storage area 40, so that a pressure difference is formed between the diversion area 10 and the storage area 40, and sewage in the diversion area 10 is squeezed to the storage area 40 under the action of the pressure difference and is stored; when the storage area 40 needs to be drained, the pressure difference disappears when the storage area is communicated with the outside atmospheric pressure, so that the sewage in the storage space 401 at this time flows into the diversion space 101 under the gravity and is discharged by the confluence pipe 30.

As an embodiment of the flow dividing region 10, it may include: a first shut-off outlet 103 and a second shut-off outlet 104, the first shut-off outlet 103 being adapted to be connected to the manifold 30 for providing an output interface for the contaminated water to be regulated, the second shut-off outlet 104 being adapted to be connected to the regulation area 40.

As an embodiment of the storage region 40, it may include: the bottom level of the buffer port 402 is lower than the bottom level of the first cut-off outlet 103, so that when the sewage input by the sewage input mechanism needs to be regulated, the sewage in the diversion area 10 flows into the regulation area 40 through the buffer port 402 for storage, and when the sewage in the regulation area 40 needs to be discharged, only the sewage stored in the regulation area 40 needs to flow into the diversion area 10 through the buffer port 402 and is discharged into the confluence pipe 30 through the first cut-off outlet 103.

As an embodiment of the vacuum pump 130, it may start a vacuum port 405 at the top of the storage region 40, and arrange a first valve 406 and a second valve 407 in parallel at the vacuum port 405; the vacuum pump 130 is communicated with the storage area 40 through the first valve 406, and the storage area 40 is communicated with the external atmospheric pressure through the second valve 407, so that when water needs to be fed into the storage area, the first valve 406 is opened, the second valve 407 is closed, the storage area 40 is vacuumized through the vacuum pump 130, a pressure difference is formed between the diversion area and the storage area, and when water needs to be drained from the storage area, the storage area 40 is communicated with the external atmospheric pressure to recover the atmospheric pressure by opening the second valve 407, and therefore the sewage stored in the storage area 40 can flow into the diversion area under the action of gravity. For the first valve 406 and the second valve 407 disposed at the vacuum port 405, in the embodiment of the present invention, the first valve 406 and the second valve 407 may be replaced by a two-position three-way electromagnetic valve, that is, the vacuum pump is communicated with the buffer portion 40 through the two-position three-way electromagnetic valve, so that the functions of vacuum pumping and communication with the atmospheric pressure are realized through the two-position three-way electromagnetic valve.

It should be noted that, for the above-mentioned intercepting inlet 102, first intercepting outlet 103, second intercepting outlet 104, and buffer port 402, the aperture size and the respective directions of the carrier are not limited, and the design can be flexibly designed according to the actual operation requirement, as long as the sewage can be communicated among the accommodating area 20, the shunting area 10, and the regulating and storing area 40, and similarly, the number of the regulating and storing areas 40 and the number of the corresponding buffer ports 402 are not limited in the embodiments of the present specification, and the design can be flexibly designed according to the actual water storage amount, and the sizes of the apertures, the directions of the respective carriers, and the number of the regulating and storing areas 40 should not be different, and are not considered to be within the protection scope of the present invention.

As an application environment of the embodiment of the present specification, for the above-mentioned sewage, a regulation node may be set according to the situations of rainfall and no rainfall for regulation, for example, if the sewage output from the accommodating area directly enters the flow mixing pipe and then is mixed with the rainwater in the presence of rainfall, the mixed water of the rainwater and the sewage is easily polluted seriously when being directly discharged into the natural water body, and if being directly discharged into the sewage treatment facility for treatment, a large amount of clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, at this time, the sewage output from the housing area 20 can be regulated by the sewage regulation and storage device provided in the embodiment of the present specification when there is rainfall, and the sewage regulation and storage can be stopped when there is no rainfall, that is, at this time, the sewage output from the housing area 20 is directly input to the confluence pipe 30;

that is, the intercepting inlet 102 of the diversion area 10 is communicated with the water outlet of the accommodation area 20 in the unit area, so that the sewage in the accommodation area 20 firstly enters the diversion area 10 before entering the merging pipe, and the diversion area 10 is communicated with the regulation and storage area 40, therefore, when the sewage needs to be regulated and stored in rainfall, the sewage output from the accommodation area 20 only needs to flow into the regulation and storage area 40 through the buffer port 402 for storage, so that only rainwater exists in the merging pipe 30, and when the sewage needs to be output in sunny days, the sewage stored in the regulation and storage area 40 only needs to flow into the merging pipe 30 through the buffer port 402 and the first intercepting outlet 103, thereby effectively avoiding the serious pollution of natural water body caused by the structural design that the sewage input from the accommodation area 20 directly enters the merging pipe for output in rainy days in the prior art, or the treatment pressure of a sewage treatment facility is too high, The technical defects of resource waste and the like can achieve the technical effect of regulating and storing the sewage when the sewage is not required to be discharged, and the sewage treatment device has the characteristics of simple structure, convenience in operation and wide applicability.

As another application environment of the embodiment of the present specification, for the above-mentioned sewage, a regulation node may be set according to the magnitude of rainfall for regulation, for example, if the rainfall is relatively large, if the sewage output from the receiving area directly enters the flow mixing pipe and then is mixed with the rainwater, the mixed water of the rainwater and the sewage is easily polluted seriously when being directly discharged into the natural water body, and if being directly discharged into the sewage treatment facility for treatment, a large amount of relatively clean rainwater in rainy days enters the sewage treatment facility for unnecessary treatment, which results in resource waste. Therefore, at this time, the sewage discharged from the housing area 20 can be regulated by the sewage regulation and storage device provided in the embodiment of the present specification when the rainfall is relatively large, and the sewage regulation and storage can be stopped when the rainfall is relatively small, that is, the sewage discharged from the housing area 20 is directly input to the flow merging pipe 30 at this time.

That is, the intercepting inlet 102 of the flow dividing region 10 is communicated with the water outlet of the containing region 20 in the unit region, so that the sewage in the containing region 20 firstly enters the flow dividing region 10 before entering the flow merging pipe, and the communication between the flow dividing region 10 and the regulating and storing region 40 is realized through the buffer port 402 of the regulating and storing region 40, therefore, when the rainfall is large and the sewage needs to be regulated and stored, only the sewage output by the containing region 20 flows into the regulating and storing region 40 through the buffer port 402, so that only the rainwater with the large rainfall exists in the flow merging pipe 30, and when the sewage is required to be output in a clear day or with the small rainfall, only the sewage stored in the regulating and storing region 40 flows into the flow merging pipe 30 through the buffer port 402 and the first intercepting outlet 103, thereby effectively avoiding the serious pollution of natural water body caused by the structural design that the sewage input by the containing region 20 directly enters the flow merging pipe to be output, or the technical defects of overlarge treatment pressure, resource waste and the like of the sewage treatment facility can achieve the technical effect of regulating and storing the sewage when the sewage is not required to be discharged, and the sewage treatment facility has the characteristics of simple structure, convenience in operation and wide applicability.

Those skilled in the art can understand that, regarding the magnitude and the size of the rainfall, the present invention is not limited, and the rainfall parameter threshold may be set according to the actual operation requirement for defining.

As another application environment of the embodiment of the present specification, for the above-mentioned sewage, a liquid level interval threshold value is preset according to a liquid level height in the storage area 40, and the liquid level height in the storage area 40 is monitored in real time, so that when the liquid level height is lower than a minimum value of the interval threshold value, it is determined that the sewage needs to be stored, that is, the sewage output by the storage area 20 flows into the storage area 40 for storage. When the liquid level is higher than the maximum value of the threshold value of the interval, the adjustment and storage of the sewage can be stopped, that is, the sewage output from the containing area 20 is directly input into the flow merging pipe 30.

That is, the intercepting inlet 102 of the diversion area 10 is communicated with the water outlet of the accommodation area 20 in the unit area, so that the sewage in the accommodation area 20 firstly enters the diversion area 10 before entering the confluence pipe, and the diversion area 10 is communicated with the regulation area 40 through the buffer port 402 of the regulation area 40, so that when the liquid level height is lower than the minimum value of the interval threshold, the storage space of the regulation area 10 is large at the moment, in order to reduce the conveying pressure of the confluence pipe, the treatment pressure of the sewage treatment facility and the like, the sewage output by the accommodation area 20 only needs to flow into the regulation area 40 through the buffer port 402 for storage, the sewage is stored when the liquid level of the regulation area 40 is low, and when the liquid level height is higher than the maximum value of the interval threshold, the sewage stored in the regulation area 10 at the moment is about to overflow, and the sewage stored in the regulation area 40 only needs to sequentially pass through the buffer port 402, The first cut-off outlet 103 only needs to flow into the confluence pipe 30, so that the technical defects of the confluence pipe, such as overlarge treatment pressure of a sewage treatment facility, resource waste and the like, can be effectively reduced, the overflow of the sewage in the regulation and storage area 40 can be effectively prevented, and the safety is high.

As another application environment of the embodiment of the present specification, a regulation node may be set according to whether there is surplus capacity in a sewage treatment plant for regulation, for example, when there is no surplus capacity in the sewage treatment plant, if the sewage output from the storage area directly enters the flow merging pipe and is then directly transported to the sewage treatment plant in a non-rainfall period, or if the sewage is mixed with rainwater and is then transported to the sewage treatment plant in a rainfall period, the treated water entering the sewage treatment plant is too much to reach the upper limit of the treatment of the sewage treatment plant, and overflow is likely to occur, so that at this time, the sewage output from the storage area 20 may be regulated by the sewage regulation device provided in the embodiment of the present specification, and when there is surplus capacity in the sewage treatment plant, the sewage regulation may be stopped, that is, at this time, the sewage output from the storage area 20 is directly input to the flow merging pipe 30.

It should be noted that the above description of the four application environments of the sewage storage device in the drainage system provided in the embodiment of the present disclosure is only an example of the practical application of the sewage storage device, and is not a limitation to the use, and those skilled in the art can also understand that the sewage storage device provided in the embodiment of the present disclosure may also be applied to other application environments that need to store and store sewage, or a combination of the four application environments, besides the above four application environments, in the drainage system, including other application scenarios that can also be applied to a specific application scenario other than the drainage system, and the present disclosure is not limited thereto. In other words, any application environment or application scenario that can store and adjust the sewage is suitable for the present invention and is within the scope of the present invention.

In the embodiment of the present specification, the storage area 40, the housing area 20, and the flow dividing area 10 may be formed integrally, that is, three areas may constitute an adjustment mechanism.

As an implementation manner in the embodiments of the present disclosure, in the adjusting mechanism, the receiving area 20 and the flow dividing area 10 may be two different areas as shown in fig. 1, which are distributed in parallel, and in this case, the flow dividing area further includes a shut-off inlet 102; at this time, the storage region 40 may include: a riser 404, one end of which is provided with a buffer port 402, wherein the buffer port 402 passes through the second shut-off outlet 104 and is communicated with the flow dividing area 10, and the bottom elevation of the buffer port 402 is lower than that of the first shut-off outlet 103; the other end of the lifting pipe 404 is communicated with the storage space 401, and a vacuum port 405 is formed at the top of the storage space 401. When water needs to enter the storage area 40, the storage area 40 is in a sealed state, the vacuum pump 130 pumps gas in the storage area 40 to form a vacuum tight chamber, then a pressure difference is formed between the storage area and the diversion area, and sewage in the diversion area extrudes the sewage in the diversion space 101 to flow into the storage space 401 through the buffer port 402, the second shut-off outlet 104 and the other end of the riser pipe 404 in sequence under the action of the pressure difference; when the water is discharged from the storage area 40, the storage area 40 is communicated with the external atmospheric pressure, so that the pressure difference disappears, and at this time, the sewage in the storage area 40 flows into the diversion area 10 through the other end of the riser pipe 404, the second shut-off outlet 104 and the buffer port 402 in sequence under the action of gravity.

It is particularly emphasized that the level of the bottom of the buffer opening 402 is lower than the level of the bottom of the first shut-off opening 103, and the closer the buffer opening 402 is to the bottom of the flow-dividing region 10, the better, so that enough sewage can flow from the riser pipe 404 into the storage region 40 when the gas is flushed into the flow-dividing space 101 by the vacuum pump 130. As a preference, the riser 404 may be of a bent type.

In yet another embodiment of the present embodiment, in the adjusting mechanism, the housing area 20 and the flow dividing area 10 may be one area as shown in fig. 2 or 3, that is, the housing area 20 may also be the flow dividing area 10. At this time, since the accommodating area 20 and the flow dividing area 10 are the same area, the flow dividing area can not omit the intercepting inlet 102; in the embodiment shown in FIG. 2, the riser 404 may be straight, and in the embodiment shown in FIG. 3, the riser 404 may be bent.

It should be noted that the storage area 40, the storage area 20, and the flow dividing area 10 provided in the embodiments of the present specification are specifically any one of the above configurations, and the present invention is not limited thereto. In other words, any one of the above structures, or other simply transformed structures, is applicable to the present invention as long as it can achieve the technical effects of enabling the sewage to enter the regulation and storage area 40 for storage under the action of the air pressure by establishing the pressure difference between the regulation and storage areas, and recovering the air pressure in the regulation and storage area when the sewage needs to be discharged, and the sewage can be discharged by gravity.

Furthermore, in the embodiment of the present specification, the flow dividing region 10 is in a well structure, and a sealing cover plate 105 is disposed on the top of the flow dividing region 10.

As an implementation manner of the sewage circulation in the embodiment of the present specification, the sewage storage and regulation apparatus further includes: the first switch 121 is disposed at the first cutoff port 103, and the third switch 123 is disposed at a position where the other end of the riser pipe 404 communicates with the storage space 401, wherein the first switch 121 and/or the third switch 123 may be any one of a gate, a weir gate, a valve, a gate valve, an air bag, an air pillow, a pinch valve, or a flexible cutoff device, and the present invention is not limited thereto, and any mechanism capable of conducting or cutting off an inlet and an outlet is suitable for the present invention, and is within the protection scope of the present invention.

As one or more implementations of the embodiments herein, the diversion area 10 is one of a diversion well, an intercepting well, a flow abandonment well, a buffer corridor, or an installation well.

Further, in the embodiment shown in fig. 1 as a real-time manner for controlling the opening and closing of the first switch 121, the first valve 406 and/or the second valve 407, the sewage storage device may further include:

the first liquid level meter is arranged in the storage area 10 and used for monitoring liquid level data of sewage in the storage area 10;

the controller is respectively communicated with the first switch 121, the third switch 123, the first valve 406, the second valve 407 and the first liquid level meter to receive liquid level data and switch the opening and closing of the first switch 121 and the third switch 123 according to the liquid level data; wherein the controller comprises a memory and a processor, the memory storing a computer program that when executed by the processor is capable of performing the steps of:

if the liquid level data is greater than or equal to the interval maximum liquid level value, the first switch is controlled to be opened, the first valve 406 is closed, and the second valve 407 is opened.
