聚合氯化铝与有机高分子絮凝剂复合应用进展

Progress on the Composite Application of Polyaluminium Chloride and Organic Polymeric Flocculant

聚合氯化铝(PAC)与有机高分子絮凝剂复合应用能提高出水水质,减少PAC用量。本文对PAC与壳聚糖(CTS)、羧甲基马铃薯淀粉(CMPS)、浒苔多糖(Ep)、海藻酸钠(SA)、非离子型聚丙烯酰胺(PAM)、阳离子聚丙烯酰胺(CPAM)、聚二甲基二烯丙基氯化铵(PDMDAAC)、聚环氧氯丙烷胺(EPI-DMA)八种有机高分子絮凝剂复合应用现状、絮凝机理做了综合评述,对无机-有机高分子絮凝剂复合应用进行了展望。

The combined application of polyaluminum chloride（PAC） and organic polymeric flocculant can improve the effluent quality and reduce the dosage of PAC. In this paper, the application status and the mechanism of flocculation about PAC and chitosan（CTS）, carboxymethyl potato starch（CMPS）, Enteromorpha polysaccharides（Ep）, sodium alginate（SA）, polyacrylamide（PAM）, cationic polyacrylamide（CPAM）,polydiallymethylammonium chloride（PDMDAAC） and epichlorohydrin-dimethylamine ploymer（EPI-DMA）, such eight organic polymer flocculants is reviewed. And the application of inorganic-organic polymer flocculants is prospected.
