Textile industry
The textile industry is one of the industrial sectors with large water consumption and high discharge of wastewater. As the world's largest producer, consumer and exporter of textiles and garments, China is the country with the most complete and complete textile industry chain. The textile processing industry wastewater contains a wide variety of pollutants and the composition is extremely complicated. The textile processing industry wastewater generally contains suspended solids, oils, lint, surfactants and various dyes. If the wastewater is discharged directly to the rivers and lakes without treatment, it will cause serious pollution to the natural environment and pose a serious threat to human survival.
