| 摘 要： | 以聚合氯化铝铁(PAFC)为混凝剂,以阴离子型、阳离子型和非离子型聚丙烯酰胺(PAM)分别为助凝剂,研究了三种PAM对焦化废水的絮凝性能。从对废水初始浊度变化的适应性、絮凝剂用量、处理效果和处理费用等几个方面比较了三种PAM絮凝性能的差异,并对絮凝机理进行了分析。对于焦化废水的絮凝处理,发现三种PAM中非离子PAM具有最好的应用性。最后对非离子PAM的最佳用量及影响因素进行了考察。最佳条件下,浊度去除率可达85%以上,但是COD去除率较低为6%左右,这与悬浮颗粒对COD的贡献较小有关。 |

| Abstract: | The flocculation of coking wastewater was studied by using poly aluminum ferric chloride(PAFC) as coagulant and anionic polyacrylamide(A-PAM),cationic polyacrylamide(C-PAM) and nonionic polyacrylamide(N-PAM) as coagulant aids.The differences in flocculation performances of the three PAMs were compared from the adaptability to the initial turbidity change of wastewater,PAM dosage,flocculation efficiency and cost.In addition,the flocculation mechanisms were analyzed.Among the three PAMs,N-PAM was found having... |
