When the filter box 403 is cleaned, the filter box 403 is placed back into the collection box 402.

[0054] In addition, the collection box 402 and the water storage bucket 101 are fixedly connected with a reflux pipe 404, and the valve of the reflux pipe 404 is sleeved.

[0055] When the sewage is added to the water storage bucket 101, the valve of the reflux pipe 404 is in a closed state, and when the collection box 402 stores sewage, the valve of the reflux pipe 404 is opened when the sewage is discharged from the drain pipe 103, so that the sewage in the collection box 402 flows back to the water storage bucket 101 through the reflux pipe 404, so as to be discharged from the drain pipe 103.

[0056] In use, the first sector plate 302 is rotated below the second sector plate 303 by the servo motor 301, and then sewage flows into the water storage bucket 101 through the water inlet pipe 102, and reagents and flocculants can be added to the sewage to purify the sewage and promote sedimentation, and the sediment settled in the sedimentation barrel 201 flows into the collection barrel 202a, and a turbidimeter can be arranged in the sedimentation barrel 201 to cooperate with the transparent cover 203 to detect the accumulation in the sedimentation barrel 201, when the sediment accumulates to a certain amount, the electric control valve 202c is opened and the sediment is discharged through the discharge pipe 202b, when the sediment content of the discharged sewage is significantly reduced, the electric control valve 202c is closed, and when the water surface in the water storage bucket 101 has floating garbage, the water storage bucket 101 is slowly filled with sewage through the water inlet pipe 102, so that the floating garbage in the water storage bucket 101 passes through the discharge cover 401 and flows into the collection box 402 along with the sewage;
