Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtering equipment, in particular to a water purification backwashing device. Background Art

[0002] Rural sewage refers to wastewater generated in rural areas that contains various wastes and pollutants. When filtering rural sewage, the use of ultrafiltration can more comprehensively filter and treat the impurities contained in rural sewage. Water purification backwash equipment is a special device used in water purification equipment, which is used to backwash and clean the filter material. The water purification backwash equipment removes the captured dirt or impurities from the filter plate by countercurrent flushing to maintain the efficient working state of the filter plate. Ultrafiltration is a physical separation technology that belongs to the field of membrane separation. It is a process of separating solutes, particulate matter and macromolecules from water through ultrafiltration membranes.

[0003] At present, most of the existing water purification backwashing equipment can only rinse and clean a single filter plate when flushing the filter plate, and cannot rinse and clean multiple filter plates at the same time, thereby reducing the efficiency of flushing and cleaning the filter plates. At the same time, only using hydraulic backwashing to flush and clean the filter plates may greatly increase the water consumption during flushing. Therefore, the utility model provides a water purification backwashing equipment to solve the problems raised in the above background technology. Utility Model Content
