Municipal sewage sedimentation tank capable of realizing efficient sedimentation of sewage

Abstract

The invention relates to the technical field of municipal sewage treatment, in particular to a municipal sewage sedimentation tank capable of realizing efficient sedimentation of sewage. The municipal sewage sedimentation tank comprises a raw water tank and a sedimentation tank, and the sedimentation tank comprises a reaction cavity, a filter cavity, an agent assembly, a stirring assembly, a filter screen, a cleaning assembly and a discharge assembly, sewage is discharged into the reaction cavity of the sedimentation tank through the raw water tank, a stored flocculating agent is put into the reaction cavity through the agent assembly, then the flocculating agent and a sewage tank are fully stirred through the stirring assembly, a driving part drives an inclined plate to turn over to fully stir the flocculating agent and the sewage tank, and after the driving part stops, the flocculating agent and the sewage tank are fully stirred. Precipitation is accelerated through the included angle formed by the inclined plate and the water surface, sewage forms floccules through stirring, the floccules are isolated by the filter screen through the water level, the floccules adhering to the filter screen are removed through the cleaning assembly, meanwhile, the floccules can be swept down to the bottom of the reaction cavity, sewage precipitation is accelerated through adsorption of the floccules, and the floccules are sucked and discharged out of the sedimentation tank through the discharge assembly, so that the sedimentation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of municipal sewage treatment, in particular to a municipal sewage settling tank capable of realizing high-efficiency sedimentation of sewage. Background technique [0002] In municipal production activities, sewage treatment has become a task that must be processed quickly, and sedimentation tanks are the core part of municipal sewage treatment facilities. In the prior art, sedimentation tanks are generally rectangular or circular pools After adding the flocculant and waiting to settle, the flocculant and sewage can fully react to form flocs through the stirring device, so that the sedimentation rate is slow and the sedimentation distance is long, which makes the sedimentation efficiency low. Contents of the invention [0003] In order to solve the above technical problems, a municipal sewage settling tank capable of realizing high-efficiency sedimentation of sewage is provided. [0004] To achieve the a...
