Description

Technical Field

[0001] The utility model relates to the technical field of coagulation and precipitation, in particular to a high-efficiency physicochemical tower capable of preventing gas blockage. Background Art

[0002] Physical sedimentation of sewage relies on the difference in density between suspended solids and water to separate them. Commonly used sedimentation tanks include horizontal flow, radial flow, vertical flow, and inclined plate tube sedimentation tanks. Vertical flow sedimentation tanks are widely used in sewage treatment due to their advantages such as convenient sludge discharge, the absence of mechanical scraping, simple management, and small footprint. However, due to water distribution, vertical flow sedimentation tanks generally have a relatively small tank diameter. When treating large water volumes, multiple tanks are required to meet sewage treatment requirements. Furthermore, sludge discharge requires extensive manual labor, and the discharge time is difficult to control. Long discharge times result in large subsequent sludge treatment volumes and increased costs. Short discharge times lead to anaerobic sludge turning and high suspended solids concentrations in the effluent.

[0003] In addition, the exhaust pipe of the existing sedimentation tank is connected to the water inlet pipe. When the gas in the pipe backflows to the water inlet, the sewage is spilled.

[0004] To overcome the above technical defects, it is now necessary to optimize and improve the original technology to obtain an efficient physicochemical tower that can prevent gas blockage and solve the above problems. Utility Model Content
