Problems solved by technology

[0002] Raw sewage is untreated domestic or industrial wastewater directly discharged by the city. Sewage treatment equipment can effectively treat domestic sewage and industrial wastewater in urban areas, avoiding sewage and pollutants from flowing directly into waters, and improving the ecological environment, improving urban quality and promoting Economic development is of great significance. Sewage treatment will go through the process of filtration and sedimentation. Generally, filter plates are used to filter sewage, and sedimentation agents are used to precipitate sewage debris. However, long-term use of debris on filter plates will affect the performance of filter plates. Filtration efficiency
[0003] The Chinese patent authorization announcement number is CN 208250055 U, which discloses a filter and sedimentation device for sewage treatment. The device is simple in structure and easy to operate, which facilitates the removal of impurities on the filter plate and the control of the release of the precipitant. amount, but the device cannot effectively treat various garbage and waste in the sewage, resulting in the garbage and waste being separated from the sewage and being discarded at will, which also causes great pollution to the environment and damages the ecological environment. great harm
