聚丙烯酰胺

聚丙烯酰胺可用于水处理。水处理包括原水处理、污水处理和工业水处理等。在原水处理中与活性炭等配合使用，可用于生活水中悬浮颗粒的凝聚、澄清。用有机絮凝剂丙烯酰胺代替无机絮凝剂， 即使不改造沉降池， 净水能力也可提高 20%以上； 在污水处理中， 采用聚丙烯酰胺可以增加水回用循环的使用率， 还可用作污泥脱水；工业水处理中用作一种重要的配方药剂。

Polyacrylamide can be used in water treatment. Water treatment includes raw water treatment,sewage treatment and industrial water treatment. In raw water treatment with activated carbon, etc.,can be used for coagulation and clarification of suspended particles in living water. If organicflocculant acrylamide is used instead of inorganic flocculant, the water purification capacity can beincreased by more than 20% even without reforming sedimentation tank. In sewage treatment, theuse of polyacrylamide can increase the utilization rate of water recycling cycle, but also can be usedfor sludge dewatering; It is used as an important ingredient in industrial water treatment.
