Description

technical field [0001] The invention relates to the technical field of filters, in particular to a filter for sewage treatment. Background technique [0002] At present, filters are widely used in metallurgy, electric power, petrochemical, environmental protection, agricultural water conservancy and other fields. General filters do not have the function of backwashing, and the filters are large in size, occupy a large space, have low efficiency, and are inconvenient to clean. After a period of time, the particles in the water adhere to the filter, and the filter needs to be stopped to clean or replace it, which will affect the continuity and efficiency of the system. Even if it can be cleaned automatically, it is not clean enough. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a filter for sewage treatment, which can clean the filter screen in the filter, realize automatic backwashing, and has shor...
