| 摘 要： | 研究了以三氯化铝,三氯化铁和阳离子聚丙烯酰胺为原料,在微波辐照下制备PAFC-PAM复合絮凝剂的工艺条件,探讨了pH值、复合絮凝剂投加量对活性染料模拟废水脱色率的影响,并考察了其对实际印染废水的处理效果。结果表明:在PAM/PAFC质量比为0.25、微波合成功率150W、微波时间3min制得的复合絮凝剂,浊度去除率为98.8%。在pH=8,投加量为42mg/L的最佳絮凝条件下,复合絮凝剂对模拟染料废水脱色率高达97%。与PAFC和PAM相比,PAFC-PAM具有较宽的pH适宜范围和较低的投加量且对实际印染废水的处理效果优于PAFC和PAM。

| Abstract: | A new type of inorganic-organic composite flocculants by microwave radiation,PAFC-PAM,was synthesized using aluminum chloride,ferric chloride and polyacrylamide as raw materials.The technique of preparation for PAFC-PAM was studied.Effects on decolorization including pH value and dosage of PAFC-PAM were discussed and treatment effects on actual dyeing wastewater were investigated.Results showed that the composite flocculants prepared under the optimal conditions of quality ratio of PAM and PAFC 0.25,microwa... |
