Textile wastewater is mainly wastewater containing natural impurities, fats, and organic matter such as starch, etc., produced during the process of raw material steaming, rinsing, bleaching, and sizing. Printing and dyeing wastewater is produced in multiple processes such as washing, dyeing, printing, sizing, etc. It contains a large number of dyes, starch, cellulose, lignin, detergents and other organic substances, as well as alkali, sulfide, various types of salts and other inorganic substances, which are highly polluting. Wastewater is characterised by high concentration of organic matter, complex composition, deep and variable chromaticity, large changes in pH, large changes in water quantity and quality, and is difficult to treat industrial wastewater.
