Description

Technical Field

[0002] Faced with increasingly severe challenges to the global environment, the consensus of all sectors of society on environmental protection is growing. As the source of life, water resources need to be protected urgently. In this context, efficient and advanced wastewater treatment equipment has become the focus of the environmental protection field. Among them, wastewater filters, as one of the key technologies, are widely used in the treatment of various industrial wastewater, domestic sewage and agricultural wastewater. Ensuring that the discharged water quality meets the standards and reducing the pollution of natural water bodies is of great significance to maintaining ecological balance, ensuring human drinking water safety and promoting sustainable development.

[0003] At present, although filter technology has been widely used in the field of wastewater treatment, there is a significant technical bottleneck that needs to be solved urgently: if the filter residue remaining on the filter plate after filtration is not effectively cleaned for a long time, it will seriously hinder the efficiency and quality of wastewater filtration. The current method is mostly to manually disassemble the filter plate to remove the residue. This process is not only cumbersome and time-consuming, greatly reducing the operating efficiency of the filter, but also frequent disassembly may accelerate the wear of the filter plate, increase maintenance costs, and thus affect the stability and economy of the entire wastewater treatment system.
