Yarn dyeing and finishing wastewater treatment equipment and treatment process thereof

Abstract

The invention discloses an yarn dyeing and finishing wastewater treatment equipment and a treatment process thereof, and the wastewater treatment process comprises the following steps: step 1, extracting textile wastewater, to be more specific, a first sewage pump is used for pumping the textile wastewater to the inner cavity of a filter box, and the flow rate is controlled to be 1500-2000 m<3> / hduring extraction; and step 2, filtering the wastewater, to be more specific, when the wastewater passes through a first filter screen and a second filter screen, the first filter screen is used for primarily filtering residual large solid particle impurities or fibers in the wastewater, and the second filter screen is used for carrying out secondary filtration on residual small solid particle impurities or fibers in the wastewater. The process solves the problems that an existing yarn dyeing and finishing wastewater treatment process is poor in treatment effect, and an emission standard is difficult to achieve in practical application, the yarn dyeing and finishing wastewater treatment process is simple, the wastewater treatment effect is good, the wastewater can rapidly reach the emission standard in practical application, the treatment stability is high, the treatment effect is good, and the wastewater treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a yarn dyeing and finishing wastewater treatment equipment and a treatment process thereof. Background technique [0002] The sewage discharged from textile dyeing and finishing mainly contains fiber dirt on yarn fibers, oils and salts coated in the dyeing and finishing process, and various sizing, dyes, surfactants, auxiliaries, Textile dyeing and finishing wastewater such as acid and alkali has the characteristics of large water volume, high content of organic pollutants, deep chroma, and large changes in water quality. It is a difficult-to-treat industrial wastewater. The increase in requirements has caused a large amount of refractory organic substances such as PVA size, rayon alkali hydrolyzate, new dyes, and auxiliaries to enter the textile dyeing and finishing wastewater, which poses a serious challenge to the traditional wastewater treatment process. The comp...
