Background

The sedimentation tank is a water quality purifying device which removes suspended matters in water by using sedimentation. The sedimentation tank can be divided into a horizontal sedimentation tank and a vertical sedimentation tank according to different water flow directions. The vertical sedimentation tank is circular or square or polygonal, and the waste water enters from a central pipe arranged in the center of the tank and is uniformly and slowly distributed on the cross section of the tank after passing through a reflecting plate from the lower end of the central pipe. Compared with a horizontal sedimentation tank, the vertical sedimentation tank has the advantages of no need of mechanical mud scraping equipment, convenience in mud discharge and small occupied area. However, in the practical use process, the purpose of water distribution is achieved by arranging a conical reflecting plate at the lower end of the central pipe in the sedimentation tank, so that the diameter of the sedimentation tank is not too large, otherwise, the problem of non-uniform water distribution is caused, and the use of the vertical sedimentation tank is greatly limited. For this reason, we propose a settling tank for sewage treatment to solve the above problems.
