Abstract

An efficient depositing pool for cleaning sewage and reclaimed water has an upper water outlet bath, a middle clarifying area, a lower sludge area connected to mud draining pipe, and a cental vertical sleeve pipe type combined reactor with the speed-variable cyclone. Said combined reactor consists of external cylindrical pipe, internal conic pipe with stirrer and cyclone guide pipe. It has also water inlet pipe and chemical applying pipe.

Description

technical field [0001] The invention relates to a fluid mixing reaction device and a water treatment device. Background technique [0002] At present, urban reclaimed water is being gradually popularized and applied, but the efficiency of the secondary water treatment tanks of traditional urban sewage treatment plants is low, and the effluent cannot meet the requirements of reclaimed water reuse. The main reason is that the content of suspended solids and total phosphorus exceeds the standard. The existing fluid mixing reaction device includes a sedimentation tank, which has a large volume, requires a large space for fluid mixing, reaction, flocculation, and sludge discharge, and consumes a large amount of electricity for water intake, stirring, and sludge discharge, and the mixing uniformity is poor. slow. Contents of the invention [0003] The present invention provides a sleeve-type variable flow rate swirl combined reactor and high-efficiency composite sedimentation t...
