Abstract

The invention discloses a waste water processing device for high-density flocculating clarification, comprising a flocculation reaction device, a clarification concentration device and a sludge returning device; the clarification concentration device are connected in series after the flocculation reaction device; the sludge returning device is connected with the flocculation reaction device and the clarification concentration device. The device has the advantages of simple and compact structure, small floor space, low energy consumption, low operating cost and high sludge concentration, standard discharge of waste water, insensitivity of water inlet fluctuation and capability for bearing flow variation within a larger range.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to equipment for drinking water, sewage, and reclaimed water reuse and purification treatment, and in particular to low-energy flocculation clarification tank sewage treatment for removing impurities in water such as suspended solids, colloids, sludge, etc. device. Background technique [0002] The high-density clarifier (DENSADEG) was first developed by the French company Deliman as a fast-closing, high-speed clarifier that adopts inclined tube sedimentation and sludge circulation. Its working principle is based on the following five aspects: the original concept of the integrated flocculation reaction tank; the slow transmission between the plug-flow reaction tank and the sedimentation tank; the external recirculation system of sludge; the mechanism of inclined tube sedimentation; the use of synthetic flocculation agent + polymer coagulant. [0003] At present, there ar...
