摘　　要：以聚合氯化铝铁(PAFC)和阳离子聚丙烯酰胺((CPAM)为原料,采用微波法制备了新型复合絮凝剂,并将其用于处理高岭土模拟废水.当CPMA与PAFC的质量比为1:4时,絮凝效果最优.红外光谱分析表明,通过微波作用,无机高分子絮凝剂已接枝到有机高分子絮凝剂上,形成了新型复合絮凝剂.该复合絮凝剂pH适应性宽,投加量少,成本低.当模拟废水pH值为6～9、投加量为1.8mg/L时,去浊率可达到98.5%以上.A new inorganic-organice Composite flocculant made by microwave from Polycrylamide(CPAM) and polyaluminum ferric chloride(PAFC).It was used to treat simulated wastwater of kaolin.The best proportion of CPAM and PAFC is 1∶4.NIR of the composite flocculant prove that the inorganic polymes flooculant had been grafter on the organic polymes by microwave.The composite flocculant has adverntage of lower adding amount,outstanding flocculation and lower cost.The removal rate of turbidity from simulant wasterwater is above 98.5% when pH is 6~9 and adding amount of the composite flocculant is 1.8 mg/L
