About a cationic polyacrylamide, field of application (1), as flocculants for sewage and organic wastewater treatment, such as alcohol, water efficient anionic flocculant pam, wastewater, monosodium glutamate factory waste water, sugar water, feed water, textile printing and dyeing wastewater. For urban sewage and meat, poultry and food processing wastewater treatment process and sludge dewatering sludge sedimentation. (2) can be used as paper dry strength agents in the paper industry, retention aid, filter aid. Can also be used for white water treatment. Meanwhile anionic polymer pam, in de-inking process can play a significant flocculation. About an anionic polyacrylamide, field of application (1), industrial wastewater treatment. Especially for a pH neutral or alkaline water, suspended particles are relatively large anionic pam, high concentrations of positively charged water, such as steel plants, electroplating plants, metallurgical plants and coal washing plant of wastewater treatment, the effect is very significant. (2), drinking water treatment. Use of the product of sediment is high, muddy water, with less drug use, low cost, no secondary pollution. (3), paper additives. Can be used as dispersants long fiber paper, wet and dry enhancer, retention and drainage aids and flocculants, such as papermaking wastewater. Coagulant anionic pam, Zhuzhou anionic pam, Hubei Saatchi Saatchi provided by the Hubei Environmental Engineering Limited. Environmental Engineering Co., Ltd.
