Sludge flocculation and sedimentation device applied to sewage disposal equipment

Abstract

The invention discloses a sludge flocculation and sedimentation device applied to sewage disposal equipment. The sludge flocculation and sedimentation device comprises a sewage disposal tank, whereina high-voltage pulse power supply is arranged on the left side of the sewage disposal tank; a stirring motor is fixedly connected to the upper surface of the sewage disposal tank; a scum treatment device is fixedly connected to the right side of the sewage disposal tank; a through hole is formed in the lower surface of the sewage disposal tank, and a sludge disposal mechanism is fixedly connectedto the lower surface of the sewage disposal tank through the through hole; the sludge disposal mechanism comprises a cylindrical shell, and the surface of the cylindrical shell is fixedly connected with the inner wall of the through hole in the lower surface of the sewage disposal tank. Through cooperative use of the structures, the problems that in the actual use process, due to the fact that sludge precipitated in a flocculation sedimentation tank is difficult to completely push into a sludge discharging pipe through a sludge scraping plate and sludge can be left on the sludge scraping plate, the sludge precipitated in the flocculation sedimentation tank is difficult to completely clean, and the the working efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sludge flocculation and sedimentation device used in sewage treatment equipment. Background technique [0002] For traditional domestic water in rural and remote areas, the flocculation and sedimentation water treatment equipment and processes are generally composed of steel sedimentation tanks, flocculant mixing tanks and sedimentation tanks. Each structure is independent and complex, covers a large area, has a wide variety of equipment and is scattered, the connection of each equipment is complicated, the control is scattered, the amount of operation and maintenance is large, and at the same time, it is necessary to add chemical liquid, causing secondary pollution, and the removal efficiency of organic pollutants Low, the sedimentation sludge can not be removed in time, which seriously affects the normal use of the equipment; for this reason, people propose...

AI Technical Summary

Problems solved by technology

[0003] However, in actual use, it is difficult for the scraper to completely push the sludge deposited in the flocculation-settling tank to the sludge discharge pipe, and there will be residual sludge on the scraper, making it difficult to completely remove the sludge deposited in the flocculation-settling tank. cleaning, reducing work efficiency
