Textile printing and dyeing sewage system

Abstract

The invention discloses a textile printing and dyeing sewage system. The textile printing and dyeing sewage system has a sewage raw water pool, an aeration and stirring adjustment pool, a biochemical treatment pool, a sedimentation pool, an ultrasonic treatment pool, an adjustment sedimentation pool, a micro-electrolysis pool, and sludge collection. pool, disinfection and regulating pool, clear water pool and control box; after the improvement of the present invention, the textile printing and dyeing sewage can be effectively treated and then recycled, which not only solves the pollution problem of textile printing and dyeing sewage to the environment, but also relieves the tension of urban water supply state. Therefore, compared with other sewage treatment facilities of the same type, the present invention has a compact overall structure, a small footprint, convenient construction, high efficiency, and low energy consumption.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing sewage treatment, in particular to a textile printing and dyeing sewage system. Background technique [0002] At present, textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. , fiber impurities, sand substances, inorganic salts, etc. Textile printing and dyeing wastewater includes desizing wastewater, cooking wastewater, bleaching wastewater, mercerizing wastewater, dyeing wastewater, printing wastewater, finishing process wastewater, and alkali reduction wastewater. At present, textile wastewater is mostly treated by physical and chemical methods, such as adsorption method, coagulation sedimentation method, etc. Among them, a single adsorbent in the adsorption method is difficult to treat textile printing and dyeing wastewater. [0003] With the continuous progress ...
