Abstract

A disclosed high-density sedimentation tank comprises a reaction area and a clarification area, the clarification area comprises a sludge scraper and a sludge circulating pipe, the sludge scraper comprises a rotating shaft and a scraping arm, and a sludge collecting cover is arranged at the lower end of the rotating shaft; the sludge circulating pipe is provided with a trumpet-shaped inlet, the trumpet-shaped inlet is arranged under the sludge collecting cover, the diameter of the trumpet-shaped inlet is gradually reduced from top to bottom, and the distance between the upper end face of the trumpet-shaped inlet and the lower end face of the sludge collecting cover is 0-500mm. By adopting the technical scheme, the inlet of the sludge circulating pipe is arranged under the sludge collecting cover and is trumpet-shaped, and the distance from the trumpet-shaped inlet to the lower end surface of the sludge collecting cover is reasonably controlled, so that the stability of muddy water at the inlet can be effectively maintained, vortex formation and sludge floating are avoided, and the sludge treatment effect of the sedimentation tank is effectively improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a high-density sedimentation tank. Background technique [0002] In recent years, with the massive discharge of domestic sewage and some industrial wastewater and garbage in our country, the treatment of water pollution has become more in-depth, and people have paid more attention to the quality of water in the process of using water resources. Therefore, high-density sedimentation tanks are often used in water treatment. Because the high-density sedimentation tank has the advantages of sedimentation and coagulation, it occupies a small area and has high usable value. It has the application characteristics of high integration, high automation, and high water yield. High-density sedimentation tank is a modern sewage treatment technology integrating flocculation, reaction, sedimentation, clarification technology and sludge concentration technology. [0003] The high-density sedimen...
