摘　　要：利用煤矿开采后产生的固体废弃物煤矸石制备一种新复合型絮凝剂聚合氯化铝铁钙(PAFCC)。制备工艺中溶出反应最优化条件为煅烧温度750℃,保温2h;盐酸的酸溶反应时间为3h,酸溶反应中盐酸的用量为0.70g/g;碱化聚合反应的最佳工艺条件:反应温度为60℃,pH值为3.7,反应时间为30min;以高岭土废水水样为处理对象,煤矸石制备的聚合氯化铝铁钙絮凝剂废水浊度去除率高于工业聚合氯化铝PAC的浊度去除率。Using solid waste,coal gangue of coal mining,to prepare a new compound flocculant-Polymeric Aluminum Ferric Calcium Chloride （PAFCC）.The optimal conditions of dissolution reaction were 750 ℃ of calcination temperature,2 h of insulation;3 h of reaction time and 0.70 g/g of hydrochloric acid of dissolution reaction.Best process conditions of alkaline polymerization reaction were 60 ℃ of reaction temperature,3.7 of pH value,30min of reaction time.For Kaolin wastewater treatment,turbidity removal efficiency of PAFCC flocculant made by coal gangue was better than that of industrial PAC.
