When there is too much mud and dirt accumulated inside the filter box 2, the staff starts the rotating motor 203. The output shaft of the rotating motor 203 drives the pulley 202 to rotate. While the pulley 202 rotates, it drives the rotating shaft of the filter box 2 to rotate on one side of the top of the sedimentation tank 1, so that the filter box 2 can be moved out of the sedimentation tank 1, so that the mud and dirt inside the filter box 2 are dumped, and the mud and dirt fall off the filter box 2 and flow out through the mud outlet trough 3, so as to avoid mud and dirt hanging on the wall outside the sedimentation tank 1, which increases the work of the staff. When larger mud and dirt enter the filter box 2 for precipitation, smaller impurities will follow the sewage through the filter eyes of the filter box 2 into the sedimentation tank 1. After a period of sedimentation, the impurities will accumulate at the bottom of the sedimentation tank 1. When the water inside the sedimentation tank 1 reaches a certain capacity, the staff opens the sluice gate 9, and the first hydraulic rod 8 inside the water outlet 7 drives the sluice gate 9 to move up into the sliding groove at the top of the water outlet 7, so that the water outlet 7 is opened, and the sewage is discharged through the water flow trough 10 on one side of the water outlet 7.
