Dyeing and printing sewage treatment device

Abstract

The invention discloses a dyeing and printing sewage treatment device which comprises a settler, wherein a first connecting tube is communicated with the top of the settler; a first water pump is communicated with one end far away from the settler, of the first connecting tube; a first water inlet tube is communicated with the other end of the first water pump; a filtering plate is fixedly mounted inside the settler; a support plate is fixedly connected with the top of the filtering plate. By adopting the dyeing and printing sewage treatment device, the situation of blocking caused by too much accumulated waste on the filtering plate is effectively avoided, wastes can be effectively collected, convenience is brought to later recycling treatment, sewage can be effectively further purified, dyes after adsorption can be collected, fine impurities in the sewage can be effectively filtered through an activated carbon adsorption plate, toxic substances in filtered water can be sterilized, and the problems of low biodegradability, high treatment difficulties and relatively poor treatment effects of an independent conventional biochemical treatment process are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a printing and dyeing sewage treatment device. Background technique [0002] Printing and dyeing wastewater is the wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. The amount of printing and dyeing wastewater is relatively large. Each ton of textile printing and dyeing consumes 100 to 200 tons of water, of which 80 to 90% become wastewater. 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. It is one of the most difficult industrial wastewater to treat. Impurities, sand substances and inorganic salts, etc. [0003] Printing and dyeing wastewater is one of the most difficult industrial wastewater recognized at home and abroad. It has the characteristics of comp...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a printing and dyeing sewage treatment device, which has the advantages of good treatment effect, low input cost, high efficiency, and convenient collection of waste after treatment, and solves the problem of poor biodegradability and difficult treatment, which alone Using the traditional biochemical treatment process, the treatment effect is poor, and it is difficult to meet the discharge requirements. The existing printing and dyeing sewage volume is too large, and it is directly treated in the pool, which will affect the sewage treatment effect, increase the input cost, and the treatment efficiency is not high.
