阳离子聚丙烯酰胺应用于工业废水处理的现状

APPLICATION STATUS OF CATIONIC POLYACRYLAMIDE IN INDUSTRIAL WASTEWATER TREATMENT

阳离子聚丙烯酰胺属于线性分子链上带有可电离基团的共聚物,可作增稠剂、絮凝剂、减阻剂等。因为其在水中发生电离后和水体中的微粒吸附、架桥,对CPAM用于水处理行业的研究越来越多。分析了近年来国内外CPAM在生活污水、油田、焦化、造纸、印染、压裂、油脂等工业废水中的应用和研究现状,对CPAM在工业废水处理的发展方向做出了展望,以期为相关研究提供借鉴和参考。

Cationic polyacrylamide is a copolymer with ionizable groups on the linear molecular chain,which can be used as thickener,flocculant,drag reducer,etc.;CPAM is more and more used in water treatment industry because of its ionization in water and particle adsorption and bridging in water.This paper mainly summarizes the application and research status of CPAM in domestic sewage,oilfield,coking,paper making,printing and dyeing,fracturing,grease and other industrial wastewater at home and abroad in recent years.It forecasts the development direction of CPAM in industrial wastewater treatment so as to provide information and reference for related research.
