Background technique

As we all know, with the continuous improvement of people's living standards, more and more sewage is produced in people's production and living. Sewage easily brings great harm to the environment. In the existing sewage treatment, it is often necessary to pass filters to the sewage. The particulate impurities are intercepted and purified to improve the quality of sewage. However, when the existing filter is in use, the intercepted impurities are easily adsorbed and deposited on the filter screen in the equipment, resulting in the inability of the sewage to pass through quickly and the purification efficiency of the equipment. The impurities inside are cleaned regularly. The cleaning of impurities is usually done manually. Workers need to drill into the equipment to clean up. The equipment is difficult to clean, not easy to operate, and consumes a lot of manpower and time. At the same time, the effect of manual cleaning is poor. Impurities are easy to remain inside.
