Abstract

The invention discloses a polluted waste liquid treatment device comprising a spiral scraper, a first inlet, a planar scraper, a jacket, a vertical scraping barrel, a rotary shaft, a cavity, a first outlet, a second outlet, a second inlet, a third outlet, a flange and a shaft seal. The polluted waste liquid treatment device is high in operable flexibility, solves the problems that the inner contact wall surface of other film scrapers is easy to scale and high-concentration liquid is insufficiently evaporated, is high in evaporation performance due to the fact that a heating surface has high surface heat flux by the aid of characteristics of the film scrapers, is heat-sensitive in treatment due to short stop time and low evaporation temperature therein, capable of completely separating severely polluted liquid into distilled water, solid-state and semi-solid state residues discharged up to standard, and thoroughly effectively treating the high-concentration liquid. Besides, the polluted waste liquid treatment device is simple in structure and convenient to operate, over-concentrated liquid in sewage is efficiently treated, sewage treatment effect is improved, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a polluted waste liquid treatment device. Background technique [0002] There are many treatment methods for traditional polluted waste liquid, including biodegradation, membrane filtration technology, vacuum multi-effect distillation, chemical treatment and other methods. However, there is a common problem that the concentrated polluted liquid after treatment is difficult to handle. Contaminated liquids that are too thick may become viscous and contain a large amount of polluting components, which will lead to the death of degrading microorganisms, clogging of filter membranes, massive fouling of distillation surfaces, reduced chemical reaction speeds, and increased processing costs. This aspect aims at the above phenomenon, focuses on the treatment of concentrated polluted liquid, and separates it into distilled water and solid and semi-solid residues discharged up to the stand...
