Abstract

The invention relates to a comprehensive sewage purification treatment device, the comprehensive sewage purification treatment device comprises a standing section, an air floatation section, an innerelectrolysis section and a biochemical plant section which are sequentially arranged in the sewage flowing direction, the bottom sludge outlet of the standing section and the bottom sludge outlet of the inner electrolysis section are sequentially connected with a sludge pump, a sludge treatment unit and a sludge-water separator, the sludge treatment unit enables sludge to release organic acids, and the supernate outlet of the sludge-water separator is also connected with the inlet of the biochemical plant section. Compared with the prior art, air floatation, internal electrolysis and biochemical plants are adopted, and combined with electron donors such as the organic acids released by the sludge ultrasound treatment and the like, the sewage in urban black-odor river channels can be treated in a combined manner, and effective ecological removal and treatment and the like of various suspended matters, organic, inorganic and other difficult-to-degrade pollutants in the sewage can be realized.

Description

technical field [0001] The invention belongs to the technical field of urban sewage purification treatment and relates to a comprehensive sewage purification treatment device. Background technique [0002] Water resources are the key resources for human production and life. With the acceleration of industrialization and urbanization, water pollution is serious. The protection of water resources and the control of water pollution have become one of the most concerned issues in modern society. Sewage treatment can effectively save and utilize precious water resources, reduce sewage discharge, reduce water environment pollution, and has obvious social, environmental and economic benefits. Biological treatment technology in sewage treatment technology has a history of one hundred years, but the pursuit of higher treatment effect and lower operating cost has always been the goal pursued by people. In addition, since most of the sewage in urban rivers is caused by the discharge o...
