Abstract

This utility model provides a sludge removal structure for the bottom of a sewage treatment tank, belonging to the field of sewage treatment technology. The sludge removal structure includes a sludge collection cylinder and a sludge retention component. The sludge retention component includes a sludge collection port, an anti-backflow pipe, a partitioning groove, a pure water tank, a water outlet, a sludge separating plate, a sludge discharge hole, and a sealing plate. Multiple partitioning grooves and sludge separating plates are provided. The sludge collection port is located on the lower inner wall of the sludge collection cylinder. The anti-backflow pipe is fixedly connected to the circumferential surface of the sludge collection port. The pure water tank is located on the upper inner wall of the sludge collection cylinder. Multiple partitioning grooves are located on the lower inner wall of the pure water tank and communicate with the inside of the sludge collection cylinder. The water outlet is located on the circumferential inner wall of the pure water tank. During the sludge removal process, the sludge is retained in the collection cylinder, while the clean water is filtered and guided into the pure water tank before being discharged.
