[0002] Domestic sewage refers to the wastewater produced by people in their daily lives. It typically contains various detergents, garbage, and feces. Domestic sewage generally contains nitrogen, phosphorus, and solid waste. To prevent domestic sewage from being discharged and polluting the environment, it must be purified using a treatment device before it can be discharged. Existing technologies often filter sewage through a filter screen, requiring the filter screen to be removed before cleaning solid impurities, which affects overall efficiency.

This technical solution simultaneously cleans solid impurities from the filter plates and filters the sewage, ensuring continuous filtration and efficient treatment.
