[0032] Specifically, when the pig farm sewage enters the treatment box 1 through the feed pipe 3, the sewage will impact on the flow baffle 4, the flow baffle 4 can slow down the flow rate of the sewage and guide the water flow direction, so that the sewage can be evenly distributed in the whole treatment box 1, avoiding the sewage directly impacting the raised plate 5 and the filter screen 7 at the bottom, thereby improving the sedimentation effect. At the right side of the bottom of the inside of the treatment box 1, a plurality of raised plates 5 are fixedly connected at equal intervals. These raised plates 5 divide the internal space of the treatment box 1 into multiple levels, forming different sedimentation areas. The left end of the raised plate 5 is provided with a main sedimentation chamber 6. The main sedimentation chamber 6 is the first sedimentation area after the sewage enters the treatment box 1, and is mainly used for sedimentation of larger solid particles and impurities in the sewage. With the residence of the sewage in the main sedimentation chamber 6, the larger particles gradually settle to the bottom of the main sedimentation chamber 6 under the action of gravity. The top of each raised plate 5 is fixedly connected with a filter screen 7. The filter screen 7 can further filter the fine particles and suspended solids in the sewage. After the preliminary sedimentation of the sewage in the main sedimentation chamber 6, the sewage continues to flow to the filter screen 7 between the raised plates 5. The pore size of the filter screen 7 can intercept the impurities with relatively light density in the sewage, so that the sewage is further purified. Meanwhile, the arrangement of the raised plate 5 increases the residence time and flow path of the sewage in the treatment box 1, so that the impurities in the sewage have more time and opportunity to settle down. At the right side of each raised plate 5, a vice sedimentation chamber 8 is arranged. The vice sedimentation chamber 8 is similar to the main sedimentation chamber 6 and is also used for sedimentation of impurities in the sewage.

The bottom of the treatment box 1 is connected with a plurality of sewage discharge pipes 9 at equal intervals. These sewage discharge pipes 9 are respectively connected with the main sedimentation chamber 6 and the plurality of vice sedimentation chambers 8. When the sewage is sedimented and filtered, the impurities and sludge settled at the bottom of the main sedimentation chamber 6 and the vice sedimentation chambers 8 can be discharged from the treatment box 1 through the sewage discharge pipes 9, avoiding excessive accumulation of the sediment in the treatment box 1 and affecting the normal operation of the equipment. The middle of each sewage discharge pipe 9 is fixedly installed with a manual valve 10. The function of the manual valve 10 is to control the opening and closing of the sewage discharge pipe 9. The operator can open the manual valve 10 regularly according to the needs to discharge the sediment from the treatment box 1. Through the sedimentation of the sewage in the main sedimentation chamber 6 and the plurality of vice sedimentation chambers 8 and the filtration of the filter screen 7, the solid particles and impurities in the sewage can be effectively removed, achieving the purpose of purifying the sewage.
