At the same time, it can prevent the increase of foam from polluting the equipment. The liquid level in the mixing barrel 1 needs to be kept below the foam discharge port 10 to prevent the liquid level from being too high and submerging the gas spray head 103.

[0035] In this embodiment, refer to Figure 3, a tee joint 341 is provided at the outer end of the liquid outlet pipe joint 34. One of the pipe interfaces of the liquid outlet pipe joint 34 is connected to the tee joint 341. The other two pipe interfaces of the tee joint 341 are respectively connected to the drain pipe 342 and the water inlet pipe 343. A drain valve 344 is provided on the drain pipe 342. When backwashing the filter screen 35 is required, the drain valve 344 provided on the drain pipe 342 is closed, and then the water inlet pipe 343 is connected to the water supply pipeline to supply water, so that clean water reversely enters the liquid outlet pipe joint 34 to wash the filter screen 35. The water passing through the filter screen 35 is discharged from the sewage outlet 30, preventing the filter screen 35 from being blocked. The filter screen 35 is stacked by multiple filter layer materials to filter impurities. For example, the first layer can be set as a metal filter screen, the second layer as a sponge filter screen, the third layer as filter cotton, and the fourth layer as a metal filter screen, achieving multi-stage filtration.
[0036] As can be seen from the above technical solutions, during use, the pig farm sewage is added into the mixing barrel 1 from the liquid adding port 11, and then the deodorant, flocculant, and disinfectant are added in sequence. Then, the driving mechanism 2 drives the stirring shaft 13 to drive the stirring blades 15 to rotate, mixing and stirring the sewage in the mixing barrel 1, so that the sewage is fully mixed with the deodorant and flocculant, eliminating the odor, and at the same time aggregating the tiny particles in the sewage to form large flocs that are easy to precipitate, so as to remove suspended solids, chromaticity, some heavy metal ions, etc., and killing the biological bacteria in the sewage. The air pump 7 supplies air to the air distribution pipe 6 and the air distribution nozzle 61, generating bubbles at the bottom of the mixing barrel 1, enabling the aerobic respiration of the activated sludge in the sewage, further decomposing the organic matter into inorganic matter, achieving the purpose of removing pollutants. The air supply pipe 102 supplies air to the gas nozzle 103, so that the ejected gas blows the foam above the liquid level in the mixing barrel 1 from the foam discharge port 10 into the foam discharge pipe 101 to separate from the sewage, preventing the bacteria from aggregating and multiplying in large numbers. Then, the hydraulic cylinder 52 drives its telescopic end to drive the guiding piston column 4 to reciprocate in the drain pipe 3. When a part of the guiding piston column 4 moves out of the drain pipe 3, the sewage in the mixing barrel 1 enters the drain hole 41 from the water inlet hole 42, and then flows into the cavity between the guiding piston column 4 and the filter screen 35. When the guiding piston column 4 completely enters the drain pipe 3, the water inlet hole 42 is blocked. The guiding piston column 4 continues to move closer to the filter screen 35. The clean water in the drain pipe 3 passes through the filter screen 35 under the action of pressure and enters the liquid outlet pipe joint 34, and then is discharged from the drain pipe 342. The impurities are intercepted by the filter screen 35. When backwashing the filter screen 35 is required, the drain valve 344 provided on the drain pipe 342 is closed and the sewage discharge valve 301 is opened, and then the water inlet pipe 343 is connected to the water supply pipeline to supply water, so that clean water reversely enters the liquid outlet pipe joint 34 to wash the filter screen 35. The water passing through the filter screen 35 takes away the impurities and is discharged from the sewage outlet 30.
