Description

[0001] Small Aquaponics System [0002]

The present invention relates to a small aquaponics system. More particularly, to a small aquaponics system using an aqua phonics siphon having a special structure.

Aquaponics is a combination of aquaculture and hydroponics. It is an eco-friendly cultivation method that uses by-products of fish ecosystem, a primary ecosystem system, as a nutrient for the second ecosystem system. It is attracting attention as a food production method. Aqua phonics system can produce various kinds of fishes and plants at the same time, and it has the effect of recycling water for biofiltering and recirculation. The aquaponics system feeds only on the fish, and the nutrients of the plant are converted from the fecal matter produced by the fish. The excreta produced by fish are discharged into ammonia or ammonium and converted into nitrite and nitrate by nitrifying bacteria present in natural soil, water and air. Since nitrifying microorganisms are naturally occurring in the presence of ammonia and nitrite, the aquaponix system can be installed in any location to provide light that the plant can grow and can be operated without restriction if the appropriate temperature is maintained. The important working principle of Aqua phonics is that the water in the eutrophicated water tank of the earthenware in the fish tank is moved to the biofilter or the nitrification microorganism with nitrification microorganism and the cultivation part where the plant grows and the purified water is returned to the aquarium It is the principle that water is circulated as the water necessary for the fish to flow in. For this purpose, a system for circulating water between a fish tank and a plant growing unit is required. Conventional techniques include a pumping method using a pump and a method using a siphon using atmospheric pressure together with a pump . Siphon means a phenomenon or mechanism that uses atmospheric pressure to move liquid from a high place to a low place. The siphon is a device that automatically discharges water at a certain level by using the difference in pressure between the atmospheric pressure and the discharge port, so that it does not require energy to operate and the maintenance cost is low. By using the advantages of these siphons and designing the Aqua phonics system, the plant growers and the water tanks are arranged vertically, then the pump is installed at the bottom, the water is moved up, the siphon is installed at the top, It is possible to design. The reason why the siphon can be used in the aqua phonics system is that it can save energy because it reduces the use of the pump as described above, as well as the aerobic nature of the nitrifying microorganism used in the aqua phonics system. Nitrifying microorganisms are aerobic bacteria that exhibit high ammonium / nitrate conversion under air-contacting conditions. When the siphon is operated in the aqua phonics system, the water in the growing section is drained through the siphon, so that it is possible to give time for air contact to the bacteria adhering to the filling material. However, the siphon has the characteristic that the operation starts or stops when the water flows in at a constant speed and the siphon is filled with water or the air layer is formed after draining. Therefore, if the inflow speed of the water to the siphon is too slow or too fast, the siphon is not filled, or the siphon does not stop because the air pressure is not greater than the atmospheric pressure because the air layer is not formed in the siphon after the drainage There are disadvantages. Therefore, aquaponix system using siphon is designed for home use to cultivate ornamental plants or small amounts of edible plants. When the size of a plant or water tank is small, it is necessary to lower the inflow rate of the nutrient solution or to increase the conversion rate of microorganisms It is not possible to operate normally if the inflow speed of water is lowered.

The microorganisms growing on the surface of the filling layer 120 are naturally occurring microorganisms and ammonium nitrification microorganisms when ammonium is present in the water. Fish excrete ammonia as feces, and ammonia accumulated above a certain concentration acts as a toxin to fish to inhibit growth. The Aqua phonics system converts ammonia into nitrate, which is used as nutrients in plants. The conversion of ammonia into nitrate is called nitrification, which means that ammonia nitrogen (NH3) is converted into nitrite nitrogen (NO2) or nitrate nitrogen (NO3) by nitrifying microorganisms.

According to an embodiment of the present invention, the nitrifying microorganism is nitromonas and the nitrifying microorganism is a nitrobactor.

The aquaponix system of the present invention includes a fish culture unit 200 including a water tank 210 in which fish can be inhabited.

The fish culture unit 200 includes a water tank 210 in which the fish can be inhabited, and the water tank is filled with a nutrient solution so that the fish can live there.

The term " nutrient solution " is used herein to refer to the circulation of the water tank 210 of the fish cultivation unit 200 and the plant cultivation tank 110 of the plant cultivation unit 100 to maintain the survival of the fish, It is the same meaning with the culture medium in the broad sense.

As used herein, the term "primary nutrient solution" refers to a nutrient solution containing fish excrement in the nutrient solution, which is transferred from the water tank 210 of the fish cultivation unit 200 to the plant cultivation tank 110 of the plant growing unit 100 Quot; secondary nutrient solution " means that the nutrient solution converted from ammonium by the nitrifying microorganism is absorbed and removed by the plant and is removed from the plant cultivation unit 110 of the plant growing unit 100, To the water tank 210 of the water tank 210.

In the present invention, the water tank is preferably connected to a frame 500 located below the plant growing tank 110 and supporting the plant growing tank 110.

The underwater pump 330 is located in the water tank 210 and is connected to the hose 310 by being immersed in the nutrient solution of the water tank. The hose 310 connected to the underwater pump 330 is connected to the plant cultivation tank 110 from the water tank 210 and connected to the end of the plant in the direction of the plant regulating vessel, The rate of inflow of the primary nutrient solution entering the bath is controlled.

The aquaponic siphon (400) of the present invention includes a casing cover (410) for protecting foreign matter from entering into a nutrient solution inlet (430) located in a casing (420); A casing 420 which makes a space between the nutrient solution inflow part 430 and the filling layer 120 and allows the secondary nutrient solution to flow into the nutrient solution inflow part through the slit 421; A nutrient solution inflow section 430 into which the secondary nutrient solution flows; A nutrient solution discharge section 440 through which the secondary nutrient solution is discharged due to the siphon phenomenon; And a drainage control device 450 for controlling the drainage amount of the secondary nutrient solution.

The aquaponic siphon 400 is located in the filling layer 120, which is installed on the bottom of the plant growing tank 110 and is stacked at the same height as the siphon. The nutrient solution discharge unit 440 is connected to the water tank 210 of the fish culture unit 200 through the bottom of the plant cultivation tank 110 and the drainage control unit 450 is disposed at the lower end of the nutrient solution discharge unit, An air inflow control bar 451 and a rubber packing 452. The air inflow control bar 451 is fixed to the inner surface of the nutrient solution discharging portion by the rubber packing 452, the number of which is inserted into the inner surface of the nutrient solution discharging portion 440 according to the inflow speed of the first nutrient solution. The number of the air inflow control bars 451 may be selected from an appropriate number, and is preferably 1 - 10.

The rubber packing 452 is inserted into the inner surface of the nutrient solution discharging portion in spite of the diameter of the nutrient solution discharging portion 440 which varies depending on the number of the air inflow adjusting bars 451 to be used, And has a diameter in a range similar to the range of the diameter of the nutrient discharge portion.

According to one embodiment of the present invention, the diameter of the rubber packing 452 is 0.8-0.99 times the diameter of the nutrient discharging portion 440.

According to another embodiment of the present invention, the diameter of the rubber packing 452 is 0.85-0.95 times the diameter of the nutrient discharging portion 440.

According to an embodiment of the present invention, the vertical length of the air inflow control bar 451 is 1.5 to 2 times longer than the vertical length of the rubber packing 452.

The small aquaponics system of the present invention operates with the following steps:

The primary nutrient solution containing the excrement of the fish cultured in the water tank 210 of the fish culture unit 200 is introduced into the nutrient solution channel 300 by the underwater pump 330; The primary nutrient solution flows from the water tank 210 of the fish culture unit 200 through the nutrient flow channel 300 to the plant growing tank 110 of the plant growing unit 100 through the valve 320 at a predetermined inflow rate step; Converting at least a portion of ammonia or ammonium in the incoming primary nutrient solution to nitrite by an asphaltene microorganism; Converting at least a portion of the nitrite to a nitrate by a nitrifying microorganism; Making at least a portion of the nitrate absorbed by the plant so that the plant grows and the nitrate is removed; The secondary nutrient solution which has reached a certain level in the plant growing tank 110 flows into the aqua phonics siphon 400 so that the siphon is operated and the secondary nutrient solution is discharged from the plant growing tank 110 through the nutrient solution discharge unit 440, Flowing into a water tank (210) of a cultivation unit (200); And a step wherein the steps are carried out organically so that nutrients are circulated.

The drainage regulator 450 of the aquaponic siphon 400 of the present invention operates as follows: First, when the level of the nutrient solution introduced into the plant growing tank 110 becomes equal to the height of the aquaponic siphon 400, Is filled with the secondary nutrient solution, and the secondary nutrient solution is discharged through the nutrient solution discharging portion 440, thereby causing a siphon effect. The discharged secondary fluid flows through the rubber packing 452, which in turn flows through the air inflow control bar 451, which is exposed on the rubber packing, to generate a turbulent flow, thereby inhibiting the discharge rate of the secondary fluid. And the inside is filled with the secondary nutrient solution. In the course of discharging the secondary nutrient solution, the outside air is introduced into the space formed by the air inflow control bar 451 inserted between the rubber packing 452 and the nutrient solution discharge portion 440 in the direction opposite to the flow of the secondary nutrient solution Thereby lowering the sound pressure inside the nutrient solution discharge section where the second nutrient solution is drained.

The present invention relates to a small aquaponics system using an aquaponic siphon. The aqua phonics siphon used in the present invention can operate normally even when the inflow speed of the nutrient solution is slow or fast so that a small home aqua phonics system for cultivating ornamental or edible plants to which an automatic drainage function is applied can be constructed.

Example

Materials and Methods

1. Fabrication of an aquaponic siphon

An aqua phonics siphon was prepared by inserting an air inflow control bar and rubber packing on the inner surface of the nipper discharge section of the siphon. In order to confirm the operation ability of the aqua phonics siphon equipped with the drainage control device, the aqua phonics siphon was installed in a plant cultivation tank and laminated with a water permeable material, and then the valve of the nutrient flow path was adjusted to adjust the inflow rate of the first nutrient solution to 0.2-4 Liters per minute and the operation of the aqua-phonic siphon was tested by adjusting the number of air inlet control bars mounted in the drainage control.

2. Fabrication of a small aqua phonics system equipped with aquaponic siphon

The small Aqua phonix system installed a fish tank and a plant growing section on the upper part of the tank that could grow plants in two stages. The tank was manufactured to a size that can accommodate a hydroponic plant cultivation apparatus of 62L was to allow the plants to grow on the surface of 0.172m ² in a volume of 21L. An underwater pump was installed in the aquaculture tank, and the first nutrient solution eutrophicated by the fish excrement was supplied to the plant growing section through the hose connected to the plant growing section. At the end of the hose connected to the plant growing section, a valve for controlling the inflow rate of the primary nutrient solution was installed, and the plant growing section was filled with a super gold hyuga stoma to plant lettuce. When a primary nutrient solution of a certain level or higher is introduced into the plant cultivation tank, an aquaponic siphon is installed in the plant cultivation tank so that the secondary nutrient solution can be automatically discharged, and the aquaponic siphon And connected to the fish culture department. To grow lettuce, a fluorescent lamp for plant cultivation was installed at the top of each plant growing area. In a sponge filter of a fish tank operated at home, microorganisms of the nitrosomonas group or nitrobactors of the group that converts ammonium or ammonia into nitrite or nitrate in the stacks deposited in the plant growing area can be purchased 50 ml of squeezed water was poured into the system and the nutrient solution was circulated for about 2 weeks without fish and plants. The aqueous ammonium concentration was maintained at 0.5 mg / L.

3. Plant growth conditions

In order to supply light to the plants, two 20W fluorescent lamps for plant cultivation were installed at the top of the plant growing area. Plants were cultivated with lettuce, the amount of sunshine was 14 hours per day, and the fluorescent lamp maintained a distance of 5 cm from lettuce. In order to prevent leaf blight from lettuce caused by bad ventilation, the slurry was stacked up to the outer wall height of the plant cultivation tank, and the room temperature was maintained at 19 to 24 ° C. Plant growth was measured by weighing the plants.

4. Fish culture conditions

Aquaculture fishes were purchased from the farms and the total weight of the fishes fed was 2% by weight per day. Feeding was carried out using Tetra Pond KOI Stics. The temperature of the fish cultivation area was kept at 19 to 24 ° C, which is the same temperature as that of plant cultivation. Considering fish breeding and microbial propagation, the pH of the nutrient solution in both the cultivation area and the aquaculture was maintained at pH 6.5 to 7.0, and the concentration of ammonium in the nutrient solution was maintained at 1 ppm or less for the stable culture of the fish. The growth of fish was measured by weighing.

5. Concentration measurement of ammonium and nitrate

The nutrient solution was sampled from the fish culturing part at intervals of 3 to 4 days and filtered with a glass fiber filter having a pore diameter of 47 mm. The concentration of ammonium in water was measured by the nessler method and the concentration of nitrate in water was measured by absorption photometry.

Experiment result

1. Operation of Aquafonic Siphon

Aqua phonics siphon which can be applied to small aqua phonics system was fabricated and the operation of siphon was measured according to the inflow rate of various primary fluids and compared with conventional siphon. The aquaponic siphon and the conventional siphon were installed in the plant growing section, and the primary nutrient solution was introduced into the plant growing tanks at a rate of 0.54, 1.2, 1.8, or 2.4 liters / min. Conventional siphon and aquaponic siphon nutrient discharges had an internal diameter of 2.5 cm. In the case of an aqua phonics siphon, the drainage regulator consisted of a single air inflow control bar 2 mm in thickness and 7 cm in length, a diameter of 2.3 cm and a length of 3 cm Rubber packing. Conventional siphons operated normally under the conditions of the first nutrient solution inflow rate of 1.2 and 1.8 liter / min, but did not operate under the conditions of the first nutrient solution inflow rate of 0.54 and 2.4 liters / minute. On the contrary, the aquaponic siphon operated under the conditions of all primary nutrient inflow rates. As described above, the reason why the aquaponic siphon normally operates at all the inflow rate conditions is that when the second nutrient solution is discharged, turbulence is generated by the air inflow control bar of the drainage control device, so that the discharge rate of the second nutrient solution is slowed down. Therefore, the siphon works because the inside of the siphon is filled by the secondary nutrient solution even under the slow inflow speed. The reason why the aquaponic siphon operates normally even under the high inflow rate is that, when the nutrient solution is discharged from the siphon, the air is introduced into the space formed between the rubber packing and the nutrient solution discharge port by the air inflow control bar of the drainage control device The difference in sound pressure between the atmospheric pressure and the nutrient discharge pipe was canceled, so that the siphon phenomenon disappeared and the operation stopped.

2. Variation of ammonium and nitrate concentration according to the difference of first nutrient flow rate

The concentration of ammonium and nitrate residues in the small aquaponix system was measured from the reaction tank which controlled the inflow rate of the primary nutrient solution fed from the fish cultivation section. The Aqua phonics system uses ammonia produced from fish excrement in the fish farming section as a nutrient for plant nutrients and the plant microbes as nutrients. Therefore, the residual amount of ammonium and nitrate is determined by the contact time between the primary nutrient solution and the microorganism introduced into the plant growing area, the amount of fish inhabited, or the air contact time of the microorganism. Experimental results showed that the amount of ammonium was below 0.4 mg / L at all inflow rates and remained unchanged until day 39 (Fig. 1). This result means that the ammonium formed at the fish culture department at all the inflow rates is removed by the microorganisms in the plant growing area, so that the fish can be cultured.

The concentration of residual nitrate was found to be less than 70 mg / L at all inflow rates (Fig. 2). The concentration of residual nitrate increased with the growth period and showed the most stable change at the flow rate of 1.2 liters / min. This is because the amount of nitrate consumed by plants and the amount of nitrate produced by microorganisms are balanced in the above conditions.

3. Plant growth according to the inflow rate of the first nutrient solution

The growth rate of lettuce was measured by varying the inflow rate of the primary nutrients from fish culture. The primary nutrient solution was introduced into four reaction vessels at different rates and the same amount of nitrogen was applied to the cultivated plants and cultured fishes. For 39 days, fish and plants were cultivated in a small aqua phonix system and growth of cultivated plants and fish growth were measured (Table 2). As a result of measuring the growth rate of the plants, the growth rate of the plant was found to be 4.4g / day, which was 128.9g at the slowest inflow rate of 0.54 liters / min, from 37g to 165g. The fastest inflow rate of 2.4 liters / Min, the total weight increased from 32.5 g to 107.8 g, which was 75.3 g, showing an average growth rate of 2.5 g / day. At a flow rate of 1.2 liters / min, the total weight increased from 110.5 g to 143.4 g at a rate of 3.7 g / day, from 32.5 g at a flow rate of 1.8 l / min to an increase of 107.7 g from a total weight of 36 g to 143.7 g / Day (Table 2 and Fig. 3). In conclusion, the inflow rate of the primary nutrient solution from fish culture was inversely proportional to plant growth. These results indicate that the rate of drainage of the plant is proportional to the flow rate of the first nutrient solution due to the nature of the siphon that discharges the nutrient solution. Therefore, the slower the flow rate of the first nutrient solution is, This is because the stress is low and the nitrate can be sufficiently absorbed and the nitrification microorganism is in contact with the primary nutrient solution and air for a long time and the conversion rate of nitrate is high.

conclusion

Aqua phonix system is an environmentally friendly hydroponic cultivation system that transforms fecal matter generated by culturing fish into plant nutrients through microorganisms and cultivates plants. In this process, the excretion of fish is converted into nitrate, which is the nutrient of plant by nitrifying bacteria, so it provides nutrients to plants and provides purified water to fish. Since nitrifying microorganisms are aerobic bacteria, the activity of microorganisms that convert ammonium or ammonia to nitrite or nitrate increases when contacted with air. In order for the nitrifying microorganism to convert ammonium or ammonia into nitrate or nitrite, the microorganism and nutrient solution must be present for more than a certain period of time. In order to meet the above requirements and improve the efficiency of the aquaponics system, it is important to control the inflow rate and the drainage rate of the nutrient solution. The aquaponic siphon applied to the present invention is advantageous in that it operates at a nutrient inflow rate over a wide range So that these conditions can be satisfied. The aquaponic siphon improves upon the disadvantages of conventional siphons and works well at slow and fast inflow rates. The air inflow control bar, which is a constituent of the drainage control device inserted into the nutrient solution discharging portion of the aqua phonics siphon, generates turbulence when discharging the nutrient solution, so that the nutrient solution inflow portion is filled with the nutrient solution even if the inflow rate of the nutrient solution is slow. There is an effect that a space in which air can flow into between the rubber packing and the nutrient solution discharging portion is formed, and even if the nutrient solution flows into the siphon at a rapid inflow rate, the sound pressure inside the siphon drops to stop the drainage. The aqua phonics system was operated under various conditions of inflow rate with the aqua phonics siphon having these advantages. As a result, the growth rate of plants was found to be faster as the inflow rate of the first nutrient solution was slower. Therefore, by using the aqua phonics siphon, it is possible to construct a small aqua phonix system in which the inflow rate of the nutrient solution is kept slow, and also, it is possible to control the inflow rate of the nutrient solution to improve the growth of the plant, System can be manufactured.

The specific embodiments described herein are representative of preferred embodiments or examples of the present invention, and thus the scope of the present invention is not limited thereto. It will be apparent to those skilled in the art that modifications and other uses of the invention do not depart from the scope of the invention described in the claims.
