[0002] The main sources of municipal sewage are domestic sewage and initial rainwater. The wastewater generated by people in their daily life activities has relatively stable water quality, but it is turbid, dark and has a foul odor. It is slightly alkaline and has high nitrogen and phosphorus content. It is very suitable for the reproduction of various microorganisms and often contains a large number of bacteria, viruses and parasite eggs, so it needs to be treated.

[0003] An existing municipal sewage treatment equipment that is convenient for treating residues in sewage usually uses a filter net to filter the residues in the sewage. The aperture of the filter net is often a fixed size, but there are different requirements for the size of the residue to be filtered at different times. The fixed-size filter net also needs to be manually replaced by staff at different times, which greatly wastes the staff's time and energy. Utility Model Content

[0024] The utility model has the following beneficial effects:

[0025] 1. Compared with the prior art, this municipal sewage treatment equipment, which is convenient for handling residues in sewage, uses a first filter plate, a waterproof motor and a limiting plate. When in use, the waterproof motor drives the screw to rotate, and the rotation of the screw drives the limiting plate to move. As the limiting plate moves, the filter holes of the first filter plate are gradually covered, and the aperture of the first filter plate is gradually reduced. In this way, the aperture of the first filter plate can be changed according to specific needs. Compared with the existing municipal sewage treatment equipment, the aperture of the filter plate is fixed, and it is impossible to filter residues with different sizes required at different times. The fixed-size filter net still needs to be manually replaced by staff at different times, which wastes the time and energy of staff. The municipal sewage treatment equipment, which is convenient for handling residues in sewage, can change the aperture size of the filter plate, can filter residues with different sizes required at different times, and no longer needs staff to manually replace the filter plate at different times, which greatly saves the time and energy of staff.

[0026] 2. Compared with the prior art, this municipal sewage treatment equipment, which is convenient for treating the residue in the sewage, uses the cylinder, the filling block, the groove and the placement box. When in use, the cylinder is first operated to drive the filling block to move into the groove. When a section of sewage is discharged, a large amount of residue accumulates at the position of the groove. At this time, the cylinder is operated again to drive the filling block to move back to the placement box. At this time, the residue moves along the groove under the action of gravity and finally falls into the storage box. After the collection is completed, the cylinder is driven again to make the filling block move back to the groove to start the next round of sewage treatment, which is more convenient for collecting the residue.

[0027] 3. Compared with the prior art, this municipal sewage treatment equipment is convenient for handling residues in sewage. Through high-pressure nozzles and limiting plates, when each round of sewage treatment begins, the water pipe behind the high-pressure nozzle supplies water, and the high-pressure nozzle sprays high-pressure water to clean the attachments that may be attached to the top of the limiting plate, so as to facilitate the next round of residue collection.

[0028] 4. Compared with the prior art, this municipal sewage treatment equipment is convenient for processing residues in sewage. Through the second filter plate, the sewage can be further filtered during use. The second filter plate is used to filter finer residues and can filter the sewage more effectively. At the same time, the second filter plate can be disassembled, which is more convenient for cleaning the second filter plate. BRIEF DESCRIPTION OF THE DRAWINGS
