About a cationic polyacrylamide, field of application (1), as flocculants for sewage and organic wastewater treatment, such as alcohol, polyacrylamide wastewater, wastewater, monosodium glutamate factory waste water, sugar water, feed water, textile 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, in the 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, high concentrations of sewage waste water treatment polyacrylamide steel positively charged, such as steel plants, electroplating plants, metallurgical plants and coal washing wastewater treatment effect very significant. (2), drinking water treatment. Use of the product of sediment is high, muddy water sludge dewatering polyacrylamide, 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.
