Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a printing and dyeing wastewater treatment device. Background technique [0002] In my country, the textile industry is a traditional pillar industry. Its total industrial production value accounts for about 10% of the national total output value, and its product market share ranks second in the world. Huge pressure, especially printing and dyeing, as an important link in the textile industry chain, discharges 80% of the pollutants in the entire industrial chain. According to statistics, 2.45 billion tons of printing and dyeing wastewater are produced nationwide every year, accounting for about 2.45 billion tons of industrial wastewater discharge in my country. 12%, ranking third among the 41 counted industries. The composition of printing and dyeing wastewater is complex, the main pollutants come from a large number of dyes and chemicals used in the processing proces...
