The pollutants of printing and dyeing wastewater are mainly the pollutants on textile fibers such as cotton wool, salts, oils and lipids, as well as the processing process, which is one of the currently hugely difficult to treat sewage.

At present, most of the treatment of printing and dyeing wastewater is polyacrylamide flocculant, which is PAM. Compared with traditional coagulants PAC (polyaluminum chloride) and PFS (polyferric sulfate), polyacrylamide flocculant has coagulation sedimentation speed. Fast, sludge volume is small, the residual amount in the water after the treatment of wastewater is low, and the treatment costs are low.
