Description

Mud discharging device for sewage treatment Technical Field The utility model belongs to the technical field of sewage treatment, and particularly relates to a sludge discharge device for sewage treatment. Background Sludge is a solid waste produced in the sewage treatment process, and consists of water, organic/inorganic particles and chemical additives, and needs to be treated to achieve reduction, stabilization and harmlessness. The sludge discharge link is a key step of sewage treatment, and relates to concentration, stabilization, dehydration and final treatment of sludge. The sludge discharging device for sewage treatment disclosed by the publication No. CN218810901U on the Chinese patent net can be used for sewage treatment, but has defects and defects to be improved (1) the existing sludge discharging device separates sludge in sewage in a gravity sedimentation mode to realize concentration and volume reduction of the sludge, but the sludge discharging method relying on natural sedimentation is low in efficiency, long in treatment period and incapable of meeting the large-scale sewage sludge discharging requirement, 2) a flocculating agent is usually added when sewage is treated to improve the separation efficiency of the sewage and the sludge, and the flocculating agent is difficult to fully mix with the sewage after being added due to the structural design, so that the flocculation effect of the flocculating agent is reduced, and 3) the existing sludge discharging device is difficult to disassemble in a regular period and incapable of replacing the sludge scraping structure due to the fact that the sludge is accumulated inside the device and is adhered to the inner wall through the sludge scraping structure after being used for a long time.
