(three).

Referring to FIG. 1 and FIG. 2, a purification device 10 for a fish and vegetable symbiosis system according to a preferred embodiment of the present invention is connected between a planting pot 12 and a culture tank 14, and the three are combined to form a a fish and vegetable symbiosis system, the planting pot 12 and the breeding tank 14 are respectively for growing vegetables and fish therein, and the purifying device 10 comprises an outer tube 20, a drainage chamber 30, a connecting tube 40, and a net. 50 and microbial attachment medium 60.

The top end of the outer tube 20 has a water injection port 22.

The drain chamber 30 is disposed inside the outer tube 20, and has a plurality of perforations 32 communicating with the inside and outside of the drain chamber 30.

The communication tube 40 extends from the inside of the drainage chamber 30 to the outside of the outer tube 20. The communication tube 40 has an opening 42 at one end of the drainage chamber 30. The height of the opening 42 is higher than the perforation of the drainage chamber 30. 32. The other end of the communication tube 40 extends into the culture tank 14 and extends below the level of the water level inside the culture tank 14.

The spacer 50 is disposed inside the outer tube 20 and is located outside the drainage chamber 30 and has a height lower than the through hole 32 of the drainage chamber 30.

The microbial attachment medium 60 is disposed inside the outer tube 20 and is located outside the drainage chamber 30. The microbial attachment medium 60 includes a plurality of first filter materials 62 and a plurality of second portions. a filter material 64, the first filter material 62 is located on the top side of the screen 50, and the second filter material 64 is located on the bottom side of the screen 50; the first and second filter materials 62, 64 are granular And the surface is rough, and the particle diameter of the first filter material 62 is larger than the second filter material 64. The first filter material 62 is attached to the nitrifying bacteria, and the second filter material 64 is attached to the denitrifying bacteria.

The height of the purification device 10 is higher than that of the culture tank 14, so that once the circulating water enters the communication pipe 40 of the purification device 10, it can be naturally guided to the culture cylinder 14; subsequently, the internal circulation water of the culture tank 14 will be It is guided to the planting pot 12, and then enters the purifying device 10, and circulates again and again; in addition, between the breeding tank 14 and the planting pot 12, and between the planting pot 12 and the purifying device 10, A pumping motor (not shown) is provided to provide the power required for the flow.

Through the above structure, referring to FIG. 2, as the circulating water flows into the tube 20 outside the purification device 10, the water level inside the outer tube 20 gradually rises, and part of the circulating water passes through the perforations 32 of the drainage chamber 30 to enter the drainage. In the cavity 30, the liquid level inside and outside the drain chamber 30 is gradually increased.

Referring again to FIG. 3, once the internal water level of the drain chamber 30 rises above the opening 42 of the communication tube 40, the circulating water of the drain chamber 30 overflows into the communication tube 40 and is directed to the culture cylinder 14; As the water flow is driven, the internal air of the drain chamber 30 is also continuously discharged through the communication tube 40, so that the air pressure inside the drain chamber 30 is gradually decreased; as the air pressure difference between the inside and the outside of the drain chamber 30 is increased, the drain The circulating water outside the chamber 30 will enter the interior of the drain chamber 30 more rapidly through the perforations 32. Once the total flow rate of the perforations 32 is higher than the inflow flow rate of the water injection port 22 of the outer tube 20, the outside of the drain chamber 30 The liquid level gradually decreases.

Referring to FIG. 4, when the external liquid level of the drainage chamber 30 gradually drops below the perforations 32, the outside air enters the drainage chamber 30 via the perforations 32 to balance the internal and external pressure difference of the drainage chamber 30; After the pressure difference between the inside and the outside disappears, the circulating water inside the drain chamber 30 flows back to the outside of the drain chamber 30 through the through hole 32, and returns to the original state (Fig. 2).

Through the above structure and procedure, when circulating water flows through the first filter medium 62, the ammonia nitrogen in the water body is oxidized to nitrite nitrogen and then oxidized to nitrate nitrogen with the action of nitrifying bacteria; The denitrifying bacteria in the second filter material 64 can further reduce the nitrate nitrogen to nitrogen to achieve the purpose of reducing the total nitrogen in the circulating water.

Since the nitrifying bacteria are aerobic bacteria, the liquid surface which is gradually raised and raised inside the outer tube 20 can make the nitrifying bacteria attached to the first filter material 62 more easily contact with oxygen in the air, thereby contributing to the nitrification efficiency. In addition, the denitrifying bacteria are anaerobic bacteria, and the spacer 50 can always limit the second filter materials 64 to the liquid surface to maintain an anaerobic environment around the cells, thereby making the denitration reaction easier.

Furthermore, the surfaces of the first and second filter materials 62, 64 are rough, which not only makes the microorganisms easy to adhere, but also effectively enlarges the surface area, and makes the growth and reproduction of microorganisms more favorable, but the surface properties thereof are not limited thereto. The first filter material 62 has a larger particle size, so that air flows easily between the filter materials, which further contributes to the progress of the nitrification reaction, and the smaller particle size of the second filter material 64 enlarges the surface area to accommodate a larger amount. Denitrifying bacteria.
