Paper industry wastewater is characterized by a large amount of water, many types, high content of organic pollutants, is one of the most difficult to treat industrial wastewater, mainly pulp wastewater and paper white water. Pulp and paper process discharge of wastewater is generally divided into pulp wastewater, kraft pulp wastewater and semi-chemical paper wastewater; its main pollutants are: ① suspended matter: mainly fibers and fiber fines; ② easy to biologically explain organic matter: mainly low molecular weight hemicellulose, methanol, acetic acid, sugar, etc.; ③ difficult to degrade organic matter: mainly lignin and macromolecular carbohydrates contained in fiber raw materials; ④ acid and alkali substances.

　　Polyacrylamide is mainly used in paper wastewater treatment for sedimentation tank, air floatation tank and depth treatment, generally using inorganic flocculants with polyacrylamide, mostly anionic for sedimentation tank, cationic for air floatation tank and both anionic and cationic for depth treatment. At the back end of the sludge dewatering process, cationic polyacrylamide is generally used. There are also some anionic sludge presses, which are relatively few.

　　The specific type of polyacrylamide to be used needs to be determined by the selection experiment according to the sludge on site. The effect of polyacrylamide treatment is mainly depends on the degree of fit, it lies in the model selection accuracy or not, which is closely related to the size of the selection range, the wider the range, the more models, it is more likely to choose the right model. Guangdong Shouxin Environmental Protection Materials Technology Co., Ltd. is a global polyacrylamide brand with stable quality, after more than ten years of development Shouxin brand polyacrylamide has two obvious advantages, in the paper industry to get a lot of customers' favor.

　　1. More models of polyacrylamide: there are 107 different models of polyacrylamide, which can provide customers with accurate selection experiments and select more cost-effective polyacrylamide models for customers.

　　2. Stability of polyacrylamide products: We can guarantee the stability of the products through professional technical engineers and advanced testing equipment, which can do strict double supervision and testing when entering the warehouse and shipping.
