Trussed sludge circulation clarifying pool

Abstract

The invention relates to a trussed sludge circulation clarifying pool. A plurality of coagulation reaction zones are uniformly arranged at the horizontal direction according to different quantities of water, each coagulation reaction zone comprises a first coagulation reaction zone and a second coagulation reaction zone with two sides arranged in a mirror image way, precipitation zones are arranged between the periphery of each coagulation reaction zone and the pool wall, the coagulation reaction zones and the precipitation zones all are connected in an integrated concrete pouring manner, a multi-phase mixer is arranged at the lower part of each coagulation reaction zone via a pipeline, a water inlet pipeline paved at the bottom of the pool is communicated with the multi-phase mixer, two trussed mud-sucking devices are symmetrically arranged in the clarifying pool and can travel on a track fixedly arranged on a cover plate of the clarifying pool, and mud-sucking pipes at the lower ends of the mud-sucking devices are arranged at the bottom of the pool. By virtue of the trussed mud-sucking devices, sludge circulation is realized, a reaction zone which integrates the functions of mixing, flocculation and precipitation is built in the clarifying pool, and the trussed mud-sucking devices can be directly applied to the sludge circulation clarifying pool and has the characteristics of high clarifying efficiency and excellent treated water quality.

Description

technical field [0001] The invention belongs to the field of sewage treatment process integration devices, in particular to a truss-car type sludge circulation clarifier. Background technique [0002] At present, the clarifiers used for water clarification and advanced sewage treatment in sewage treatment mainly include two forms, namely sludge suspension clarifiers and sludge circulation clarifiers. Among them, the sludge circulation clarifier mainly refers to the mechanical stirring clarification tank, which requires mechanical stirring equipment, the structure of the tank body is complicated, and the maintenance is troublesome; the sludge circulation clarification tank mainly refers to the hydraulic circulation clarification tank, without mechanical stirring equipment, and the structure is relatively It is simple, but consumes a large head of water, and the pressure of the water source is high. The sludge suspension type clarifier also needs a set of vacuum equipment, th...
