Problems solved by technology

[0002] As an effective facility for removing suspended solids in water, sedimentation tanks have been widely used in water treatment. However, due to the low treatment efficiency of existing sedimentation tanks in sewage treatment plants, they cannot effectively remove impurities such as COD and SS in sewage. The optimal treatment effect of the sedimentation tank is not fully utilized, and at the same time limited by land resources, it is necessary to improve the existing sedimentation tank, which can not only improve the removal rate of COD and SS, but also reduce the processing load of other links and save Land area, sewage treatment cost and engineering investment, etc.

Abstract

The invention provides a baffled sedimentation tank and a baffled sedimentation process; the sedimentation tank is selected from any one of the below, firstly, the sedimentation tank includes a water inlet tank, a water outlet tank, bottom slopes and a suction dredger; the water inlet tank is arranged along the pond length direction, the water inlet tank is adjacent to the water outlet tank and in parallel to the water outlet tank; the bottom slopes are arranged at both sides of the inner wall of the baffled sedimentation tank; the mud dredger includes a mud dredging pipe and a mud dredging unit; the mud dredging pipe is arranged in the baffled sedimentation tank, and the mud dredging pipe is connected with the mud dredging unit; secondly, the sedimentation tank includes a water inlet tank, a water outlet tank, a bottom slope, a suction dredger and a center cylinder; the water inlet tank is arranged along the periphery of the baffled pond, and the center cylinder is arranged in the center of the baffled sedimentation tank. The baffled sedimentation tank and the baffled sedimentation process are small in land area, and can avoid riffle, vortex, short current, stagnant water, sludge deposit, and other phenomenon of an ordinary sedimentation tank; the water flow field is evenly distributed, the volume utilization rate of the pond body is high, and the sedimentation efficiency is high.
