Dyeing and printing sewage treatment device

Abstract

The invention discloses a printing and dyeing sewage treatment device, which comprises a sedimentation tank, the top of the sedimentation tank is connected with a first connecting pipe, and the end of the first connecting pipe far away from the sedimentation tank is connected with a first water pump, and the first water pump The other end of the settling tank is connected with a first water inlet pipe, a filter plate is fixedly installed inside the settling tank, and a support plate is fixedly connected to the top of the filter plate. The printing and dyeing sewage treatment device effectively avoids the blockage caused by excessive accumulation of waste on the filter plate, effectively collects the waste, facilitates subsequent recycling, effectively further purifies the sewage, and can absorb After the dye is collected, the fine impurities in the sewage can be effectively filtered through the activated carbon adsorption plate, and the toxic substances in the filtered water can be sterilized, which solves the problem of poor biodegradability and difficult treatment. Biochemical treatment process, the problem of poor treatment effect.

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.
