Polyacrylamide is used to treat tannery wastewater
Polyacrylamide treats leather wastewater. The tannery will produce a large amount of sewage during the leather production process. This sewage has high concentration, strong alkalinity, high oxygen consumption, and a lot of suspended particles in the water quality. A large number of various chemicals are added during the leather processing process, so the sewage is more complex and contains acids, alkali, dyes, sulfides, sugar, grease, protein, wool fiber, dander, suspended A variety of mixed organic and inorganic substances, such as Cr3+, S2-, and suspended particulate matter in the water, make water pollution more serious. Therefore, tannery factory wastewater treatment is more difficult, and it is also a relatively complex type of wastewater in the water purification industry.
