高分子絮凝劑是工業(yè)污水處理和城市生活污水處理常用的一種水處理藥劑。按照其化學成分總體可分為無機絮凝劑和有機絮凝劑兩類。

　　有機高分子絮凝劑如聚丙烯酰胺（PAM），它由丙烯酰胺（AM）單體經(jīng)自由基引發(fā)聚合而成的水溶性線性高分子聚合物，具有良好的絮凝性，可以降低液體之間的摩擦阻力，按離子特性分可分為非離子、陰離子、陽離子和兩性型四種類型。聚丙烯酰胺PAM也是污水處理較為常用的水處理藥劑。

　　使用經(jīng)濟，在很低的投加量下，就可以取得很好的使用效果；可以顯著提升生產(chǎn)效率或提升泥餅的固含量；在水中很容易溶解；在生產(chǎn)過程的固液分離中，可以提升固形物的捕捉率；在較寬的pH值范圍內(nèi)工作。

Polymer flocculant is a water treatment agent commonly used in industrial sewage treatment and urban domestic sewage treatment. According to its chemical composition, it can be divided into inorganic flocculants and organic flocculants. Organic macromolecular flocculants such as polyacrylamide (PAM), 

which is a water-soluble linear macromolecular polymer formed by free radical polymerization of acrylamide (AM) monomers, has good flocculation and can reduce the amount of liquid Frictional resistance can be divided into four types: non-ionic, anionic, cationic and amphoteric according to ionic characteristics. Polyacrylamide PAM is also a commonly used water treatment agent for sewage treatment. It is economical to use, and can achieve good results at a very low dosage; it can significantly improve production efficiency or increase the solid content of mud cake; it is easily dissolved in water; in the solid-liquid separation of the production process, it can be Improves solids capture; works over a wide pH range. volume_upcontent_copyshare
