Specific implementation manner
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a circulating purification system for treating the tail water of seawater aquaculture, including an aquaculture pond 1. The lower end of the aquaculture pond 1 is connected in communication with a water pipe 8. The water pipe 8 is connected with a first circulation pump 2. The water outlet end of the first circulation pump 2 is connected with a filtering device. The water outlet end of the filtering device is connected with a biological reaction device. The water outlet end of the biological reaction device is connected with a foam separator 7. The foam separator 7 is connected with a disinfection device through the water pipe 8. The disinfection device is connected with a second circulation pump 10 through the water pipe 8. The water outlet end of the second circulation pump 10 is connected with a circulation pipe 11. The end of the circulation pipe 11 extends into the upper part inside the aquaculture pond 1; the water in the lower part of the aquaculture pond 1 contains relatively high suspended matter and relatively high pollutant concentration. The water at the lower end of the aquaculture pond 1 is pumped out through the water pipe 8 by the first circulation pump 2. The pumped water enters the filtering device. First, the suspended matter in the water is filtered out by the filtering device. Under the action of the first circulation pump 2 and the second circulation pump 10, the water flows along the water pipe 8 into the biological reaction device. Through the action of biological reaction, nitrogen, phosphorus, and organic matter in the water are removed. The water after passing through the biological reaction device enters the foam separator 7 to remove suspended foam. Then the water flows into the disinfection device, and through further disinfection treatment of the water, the second circulation pump 10 injects the treated water into the upper part inside the aquaculture pond 1 through the circulation pipe 11 to form a stable cycle, and can purify the water and improve the aquaculture quality of the water.
[0022] Such as Figure 3As shown in the figure, the filtering device includes: a coarse filter 3, which is connected to the breeding pond 1 through a water pipe 8. Inside the coarse filter 3, there is a coarse filter screen 12 driven by a motor; a micro filter 4, which is connected to the coarse filter 3 through a water pipe 8. Inside the micro filter 4, there is a micro filter screen 13 driven by a motor. The water is filtered by the coarse filter 3 and the micro filter 4. Among them, inside the coarse filter 3, there is a coarse filter screen 12 driven by a motor, and the aperture of the coarse filter screen 12 is set in the range of 80 - 120 meshes. Similarly, the micro filter screen 13 is driven to rotate by a motor, and the aperture of the micro filter screen 13 is set between 400 - 600 meshes. Through two filtering steps, the maximum filtering treatment can be achieved during the treatment of the breeding water.
[0023] As Figure 1 shown in the figure, the biological reaction device includes: a reaction tank 5. Inside the reaction tank 5, there is a water distribution pipe 14. At the upper end of the water distribution pipe 14, there is an aeration head 16 fixedly connected.

Oxygen is injected into the air pipe 15 through the aerator 6, and oxygen is injected into the aeration head 16 through the air pipe 15, and oxygen is injected into the reaction tank 5 to form bubbles. In this way, the water can be churned, and the churned water undergoes biological reactions through the packing layer 17. A large number of microorganisms are enriched in the packing layer 17, and thus nitrogen, phosphorus, and organic matter can be removed. Then, the water treated biologically flows into the foam separator 7 to remove foam. At the same time, the water can be fully injected into the reaction tank 5 through the water distribution pipe 14, and the water distribution pipe 14 is located at the lower end of the aeration head 16, forming an upper and lower layer distribution, and the aeration head 16 can achieve a better effect of generating bubbles.
[0024] As Figure 1 shown in the figure, the disinfection device includes: a disinfection tank 9, which is connected to the foam separator 7 through a water pipe 8. At the upper end of the disinfection tank 9, there is an ultraviolet disinfection lamp 18 fixedly connected. The number of ultraviolet disinfection lamps 18 is multiple and covers the upper end of the disinfection tank 9; the water in the disinfection tank 9 is irradiated with ultraviolet rays through the ultraviolet disinfection lamp 18 fixedly connected to the upper end, thus forming ultraviolet disinfection to further disinfect the water. The multiple ultraviolet disinfection lamps 18 cover the upper end of the disinfection tank 9, thereby achieving comprehensive coverage for disinfection.
[0025] As Figure 2As shown, a collection pipe 19 is arranged inside the aquaculture pond 1. The number of the collection pipes 19 is multiple, and the collection pipes 19 are connected to the water pipe 8. The collection pipes 19 are arranged at the lower end inside the aquaculture pond 1 and are connected to the water pipe 8. The multiple collection pipes 19 can comprehensively collect the suspended matters at the lower end of the aquaculture pond 1 in all directions.
[0026] As Figure 5 As shown, an extended lampshade is arranged outside the ultraviolet disinfection lamp 18, and the lampshades are fixed against each other; through the extended lampshade, the ultraviolet disinfection lamp 18 can irradiate the water in an extended manner, achieving a better disinfection effect.
