[0002] Textile printing and dyeing wastewater refers to the wastewater discharged from printing and dyeing, wool dyeing and finishing, and silk factories that mainly process cotton, linen, chemical fibers and their blended products, and silk. The amount of wastewater from printing and dyeing factories is relatively large. Each printing and dyeing process of 1 ton of textile consumes 100 to 200 tons of water, of which 80% to 90% is discharged as wastewater. 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 difficult-to-treat industrial wastewaters. Textile printing and dyeing wastewater treatment device is a device used to treat textile printing and dyeing wastewater. Its function is to reduce the pollutant content in the wastewater to meet the discharge standards or recycle it for reuse.

[0003] The existing textile printing and dyeing wastewater treatment equipment is mainly composed of sedimentation tanks, biochemical tanks, filtration tanks and pipeline systems. The working principle is: in the sedimentation tank, the particulate matter in the sewage is precipitated to the bottom of the tank due to gravity or chemical reactions, thereby removing some pollutants. The precipitated sewage enters the biochemical tank, where biodegradable organic pollutants are decomposed into inorganic matter and water under the action of microorganisms. Then, the sewage enters the filtration tank, and the filter material in the filtration tank further adsorbs and intercepts the fine particulate matter and residual soluble substances in the sewage, so that the sewage is purified.

[0004] At present, when the textile printing and dyeing wastewater treatment device in the prior art filters and treats the textile printing and dyeing wastewater, the textile printing and dyeing wastewater contains a large amount of impurities such as suspended matter, fiber, slurry, etc. These impurities can easily clog the filter holes of the filter, requiring frequent cleaning and replacement of the filter element, increasing the operating cost and maintenance workload; therefore, a textile printing and dyeing wastewater treatment device is proposed to address the above problems.
