摘要：

报道了自制和市售的几种阳离子聚丙烯酰胺对废纸再生造纸废水处理的研究过程。比较了无机混凝剂聚合氯化铝或有机絮凝剂阳离子聚丙烯酰胺单独使用时和无机混凝剂与有机絮凝剂配合使用时处理废水的效果。结果表明:无机混凝剂与有机絮凝剂配合使用时有很好的处理效果。用自制阳离子聚丙烯酰胺 (PDA)与PAC配合处理废纸再生造纸废水, 出水COD去除率达75%以上, 透过率达92%-99%。

Abstract:

The treating processes of papermaking waste water by PDA prepared by our laboratory and some kinds of cationic poly acry lamide in the market are reported.The performances of inorganic coagulant(PAC), organic flocculant(cationic polyacrylamide)and the composite of inorganic and organic flocculants in treating papermaking waste water have been compared.The results show that the performance of the composite of inorganic andorganic flocculants is excellent.COD elimination efficiency of the treated water can reach75% or more, and the transmit tancy can reach 92%-99%

Key words: papermaking waste water, treatment of waste water, coagulate, cationic flocculant
