【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%。更多还原

【Abstract】 The treating processes of papermaking wastewater by PDA prepared by our laboratory and some kinds of cationic polyacrylamide 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 wastewater have been compared. The results show that the performance of the composite of inorganic and organic flocculants is excellent.COD elimination efficiency of the treated water can reach 75% or more, and the transmittancy can reach 92%～99%.更多还原
