[0019] 4. The processing box uses the second positioning sleeve for the lower end of the filter sleeve to be embedded, so that the lower end of the filter sleeve is positioned by the second positioning sleeve;

[0020] 5. The upper end of the filter mesh sleeve is embedded in the first positioning sleeve and the lower end is embedded in the second positioning sleeve, so that the first fixing ring and the second fixing ring are in contact with each other, and then the fixing bolt is passed through the first through hole and the second through hole and then connected by the nut thread. At this time, the filter mesh sleeve can be detachably connected to the middle part of the treatment box, which is convenient for cleaning the fluff in the filter mesh sleeve after removing the filter mesh sleeve;

[0021] 6. After being filtered by the filter mesh, the wastewater can flow into the sedimentation buckets on both sides, where the wastewater can settle, so that the sludge in the wastewater settles to the bottom of the sedimentation bucket, and then the sludge is discharged through the sludge discharge pipe; at the same time, the clean water on the upper layer of the sedimentation bucket can be discharged through the drainage pipe;

[0022] 7. The inner wall of the sedimentation bucket is tilted toward the side of the sludge discharge pipe, which can help the sludge discharge pipe to efficiently discharge the sludge in the sedimentation bucket. BRIEF DESCRIPTION OF THE DRAWINGS
