Description

Technical Field

[0001] The utility model relates to the field of sewage treatment sedimentation tanks, in particular to a sewage treatment sedimentation tank. Background Art

[0002] A sewage sedimentation tank is a type of equipment used to treat sewage, mainly used to precipitate and separate solid particles and suspended matter in sewage. By utilizing gravity, the sewage is allowed to remain in a static state for a period of time, so that the solid particles in it settle to the bottom and form a sludge layer. The supernatant flows out from the upper part of the sewage sedimentation tank and can be recycled or discharged into the environment after further treatment. It can effectively remove suspended matter and solid particles in sewage and reduce the burden on subsequent treatment equipment. At the same time, it can also reduce the organic matter load in sewage, reduce chemical oxygen demand and biochemical oxygen demand, and help improve the effect and efficiency of subsequent treatment processes.

[0003] After the existing sewage treatment sedimentation tank has been used for a period of time, in order to ensure the sedimentation quality, the sludge in the tank needs to be removed.
