摘要： 为回收赤泥中的铝铁成分,解决赤泥污染和占地问题,提出了利用赤泥制备聚合氯化铝铁(PAFC)的新方法.以废水中高岭土为处理对象,与聚合氯化铝(PAC)进行了混凝对比实验,考察了混凝剂投加量、废水pH值、废水浓度、废水温度、盐基度等因素对絮凝效果的影响.实验结果表明:混凝剂的投加量、废水pH值、盐基度、废水浓度等对混凝效果有明显影响,温度对混凝效果的影响较小,PAC最高去浊率为93%,PAFC最高去浊率达到96%.

Abstract: To recover aluminum and iron from red mud and, simultaneously, prevent the environment pollution and occupancy of large-area land from the recovery, the polyaluminium ferric chloride(PAFC) was prepared with red mud, to treat the kaolin-containing wastewater. A contrast test was carried out with PAFC and PAC(polyaluminium chloride) both used as flocculants to investigate the effects of the dose of flocculants, the pH value, concentration and temperature of wastewater, and basicity on flocculation. The results indicated that all the influencing factors as above except the wastewater temperature affect the flocculation greatly. The maximum depollution rate by PAC is 93%, while that by PAFC comes up to 96%.
