[0002] Municipal sewage refers to domestic sewage, industrial wastewater and runoff sewage within the scope of urban areas. It is generally collected by urban pipes and should be discharged into water bodies after being treated in urban sewage treatment plants. In addition to containing a large amount of organic matter, pathogens and viruses, urban sewage also contains various types and degrees of toxic and harmful pollutants due to the rapid development of industry, the amount of industrial wastewater (accounting for about 60-80% of the total amount of urban sewage) and the increasingly complex water quality and increasingly serious pollution of runoff sewage. The treatment of urban sewage involves many aspects, and comprehensive planning must be carried out for the sewer system, the location and treatment process of sewage treatment plants, and the utilization and discharge requirements of treated sewage.

[0003] Municipal sewage is generally collected by urban pipes and discharged into water bodies after being treated in urban sewage treatment plants. In the process of treating municipal sewage, it is necessary to separate the solid waste from the sewage. In the prior art, a filter is mostly used to filter and separate the solid waste. The principle is to filter the waste by the gravity of the water itself. However, if the solid waste is only filtered by the gravity of the water itself, as the working time increases, the solid waste in the sewage is easy to accumulate on the filter, causing the filter to be blocked, reducing the filtration efficiency of the filter, and ultimately affecting the sewage treatment efficiency.

[0004] Therefore, it is necessary to provide a sewage treatment device for municipal engineering. Utility Model Content
