[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: an aeration immersion type water treatment and filtration device, which includes a filtration tank 1. A water inlet pipe 2 is connected and communicated at the lower end of the filtration tank 1. An outlet pipe 3 is connected and communicated on the other side of the filtration tank 1. A sedimentation area is arranged on one side inside the filtration tank 1. An aeration mechanism is arranged at the bottom end inside the filtration tank 1. A filtration mechanism is fixedly connected to the upper end of the aeration mechanism. The filtration mechanism includes a first filter screen 7 and a second filter screen 8. The first filter screen 7 and the second filter screen 8 are respectively arranged at the upper and lower ends inside the filtration tank 1. A packing member 9 is arranged between the first filter screen 7 and the second filter screen 8. A retaining plate 5 is fixedly connected to the upper end of the filtration tank 1. A gap is formed between the outer side wall of the retaining plate 5 and the inner side wall of the filtration tank 1 to form a water collection tank 6; the aquaculture tail water enters the inside of the filtration tank 1 through the water inlet pipe 2. After entering the filtration tank 1 through the water inlet pipe 2, as the water level rises, the tail water first passes through the second filter screen 8, then through the packing member 9, and finally flows into the water collection tank 6 through the first filter screen 7, and then flows into the sedimentation area through the water collection tank 6. After sedimentation in the sedimentation area, it flows out through the outlet pipe 3. At the same time, when the tail water passes through the second filter screen 8 and the first filter screen 7, the aeration mechanism performs foaming treatment on the tail water, so as to achieve a better effect of separating the tail water and a better filtration effect.

[0022] As Figure 2 shown, the aeration mechanism includes: an aerator 4. An air pipe 12 is fixedly connected to the air outlet end of the aerator 4. An air diffuser 11 is fixedly connected to the air pipe 12. A water distribution hole 10 is opened at the upper end of the water inlet pipe 2 inside the filtration tank 1. The air diffuser 11 is arranged between the water distribution holes 10 and is fixedly connected to the upper end of the water inlet pipe 2; the aerator 4 injects external oxygen into the air pipe 12, and the oxygen is released from the air diffuser 11 through the air pipe 12. In this way, dense bubbles are formed by the air diffuser 11, and the tail water uniformly injects water into the bottom of the filtration tank 1 through the water distribution holes 10 opened on the water inlet pipe 2. After the water is injected, bubbles are injected by the air diffuser 11, and then the air diffuser 11 blows air upward to make the water inside tumble, so as to make the packing member 9 rotate. When the packing member 9 rotates, it can cut the bubbles, so as to achieve a better contact between the sediment and the first filter screen 7 and the second filter screen 8.

[0023] As Figure 1 shown, the aperture of the first filter screen 7 is set smaller than that of the second filter screen 8; the tail water moves from the second filter screen 8 to the first filter screen 7, and as the aperture decreases, foreign matter sediments of different sizes can be filtered and isolated to achieve the filtration effect.

[0024] As Figure 4 shown, the packing member 9 is filled in half of the volume between the first filter screen 7 and the second filter screen 8, Figure 4The state in which the packing member 9 shown in the figure is impacted and tumbled by the tail water. The packing member 9 tumbles and rotates between the first filter screen 7 and the second filter screen 8 to cut the bubbles. The packing member 9 filled with half of its volume can rotate fully when the water is full.

[0025] As Figure 3 shown, the position of the water outlet pipe 3 is set flush with the upper water surface of the water collection tank 6. The water outlet pipe 3 is located flush with the end surface of the water collection tank 6. In this way, the water precipitated in the sedimentation area is discharged from bottom to top. Thus, the discharged water is the water after precipitation, and the discharged water is clearer and free of foreign matters.

[0026] As Figure 4 shown, the packing member 9 is provided with a spherical hollow and is enriched with microorganisms on the surface. The spherical packing member 9 is convenient for internal rotation. The hollow setting of the packing member 9 is convenient for water impact and tumbling, and is also convenient for cutting bubbles, and can enrich more microorganisms.

[0027] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
