Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment, in particular to a domestic sewage treatment device for municipal water supply and drainage. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used and increasingly enters the daily lives of ordinary people. In the field of sewage treatment technology, a domestic sewage treatment equipment for municipal water supply and drainage is used.

[0003] According to the description of a domestic sewage treatment equipment for municipal water supply and drainage disclosed on the patent website (authorization announcement number: CN115072932B), "The present invention discloses a domestic sewage treatment equipment for municipal water supply and drainage, including a sewage treatment box, which is divided into five chambers: a biochemical tank, an aeration tank, an MBR membrane tank, a degradation tank and a control room. The bottom of the front side of the sewage treatment box is connected with four first valves, and the four first valves are used in conjunction with the biochemical tank, the aeration tank, the MBR membrane tank and the degradation tank respectively. The top of the sewage treatment box is connected with four box bodies. The present invention solves the problem that the existing domestic sewage treatment equipment for municipal water supply and drainage does not have the function of regularly cleaning the filter plate in the filter mechanism by arranging a sewage treatment box, a first valve, a box body, a first water pump, a first filtering mechanism, a second filtering mechanism, a first connecting pipe, a second water pump, a second connecting pipe, a bioreactor, a third water pump, a third connecting pipe, a doser, a drug outlet pipe, a fan unit, a first air duct, a second air duct, a control box, an aeration pipe and a box cover for coordinated use."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the sewage is deeply filtered through the first filter plate and the second filter plate and then flows out of the filter box through the outlet pipe. After the first filter plate has cleaned the sewage for a long time, the output end of the motor drives the threaded rod to rotate. The threaded rod drives the threaded sleeve to move forward when rotating, and the threaded sleeve drives the brush plate to move forward. The brush plate will brush the surface of the first filter plate when moving. However, in actual use, the filter plate is fixed inside the device by bolts. When the filter screen is damaged, it is inconvenient to replace it. Secondly, the drain pipe is opened through the valve to discharge the dirt at the bottom. However, the drain pipe has a small area and impurities are easily accumulated inside and cannot be discharged. Therefore, it is necessary to improve a domestic sewage treatment equipment for municipal water supply and drainage to solve the above problems. Utility Model Content
