technical field

The utility model relates to the technical field of sewage treatment, in particular to a sedimentation tank for sewage treatment.

Background technique

A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. Sedimentation tanks are generally structures for the separation of mud and water before or after biochemical treatment, and mostly separate sludge with finer particles. The sedimentation tank before the biochemical process is called the primary sedimentation tank, and the sedimentation tank after the biochemical process is generally called the secondary sedimentation tank.

Generally, the sedimentation tank has poor sedimentation efficiency and takes too long, and the sludge at the bottom of the sedimentation will completely enter the clean water chamber without sedimentation with the water flow, which increases the difficulty of sedimentation. In view of this, we propose a sewage treatment sedimentation tank to solve the above problems.
