阳离子型有机絮凝剂研究进展

Advances in cationic organic flocculant

絮凝剂是絮凝法水处理技术的核心 ,目前阳离子高分子絮凝剂作为龙头产品受到人们广泛关注。就国内外阳离子有机絮凝剂的研究开发和应用进行评述 ,内容涉及阳离子型聚丙烯酰胺接枝共聚物、羟基醚化类、烷基烯丙基卤化铵类和环氧氯丙烷与胺反应物 。

A flocculant is the core of coagulation technology.At present,the cationic high polymer flocculants,as the key products,have received concern extensively.R&D and applications of the cationic organic flocculants at home and abroad are reviewed,including the graft copolymerization of cationic mould polypropylene,hydroxyl etherification,the variety of alkenes and alkyl halogenated ammonium,the reactant of 3 chloropropylene oxide and amine,etc.Especially,the synthetic nonpoisonous cationic high polymer flocculants and the modified cationic high polymer flocculants from natural high polymer such as the starch are summarized and discussed.
