Abstract

The invention discloses an inclined-plate sedimentation tank for sewage treatment. The inclined-plate sedimentation tank comprises a feeding port, overflow ports, a plurality of inclined plates, a transition layer, a flow blocking plate, a sludge discharging pipe and a plurality of sludge hoppers; the plurality of sludge hoppers are arranged at the lower end of the sedimentation tank; a sludge discharge pipe is arranged at the bottoms of the sludge hoppers; the flow blocking layer is arranged above the sludge hoppers; the surface of the flow blocking layer is provided with the plurality of inclined plates; a slow flow layer is arranged on the upper ends of the inclined plates; each of two ends of the sedimentation tank is provided with one overflow port; and the feeding ports penetrate through the sedimentation tank and are located above the slow flow layer. According to the inclined-plate sedimentation tank provided by the invention, the inclined plates, the flow slowing layer and theflow blocking layer are effectively combined, so that the flow speed of a sedimentation material is moderate, and the sedimentation effect and the sedimentation rate of the sedimentation tank are effectively improved. The sludge discharge pipe is arranged at the bottoms of the sludge hoppers, so that the sludge discharging effect and the sludge discharging rate of the sedimentation tank are effectively improved.

Description

technical field [0001] The invention relates to a settling tank, in particular to an inclined plate settling tank used for sewage treatment. Background technique [0002] Inclined plate sedimentation tank is an environmental protection equipment used to remove suspended solids in wastewater. It is widely used in industrial sewage treatment, domestic sewage treatment and high-concentration sewage treatment and other fields. The existing sloping plate sedimentation tanks have the problems of excessively fast sedimentation material flow rate, poor sedimentation effect, and poor sedimentation rate. In addition, the sludge discharge pipes of the existing sloping plate sedimentation tanks are generally installed above the sludge hopper, and the sludge discharge The effect is not good, and the mud discharge speed is relatively slow. Therefore, designing a sedimentation tank that can solve the above problems is a problem to be solved urgently at present. Contents of the invention ...
