摘　　要：制备了含锌絮凝剂聚合氯化铝锌(PAZC),并通过铝试剂分光光度法研究了聚合氯化铝锌(PAZC)和聚合氯化铝(PAC)处理废水后的残留铝含量。探讨废水pH值、絮凝剂投加量、沉降时间及絮凝温度对废水残留铝含量的影响。结果表明,经聚合氯化铝锌处理后废水余铝率最低达到7.2%,远小于PAC10.2%的余铝率。A novel polymeric aluminum zinc chloride（PAZC） was prepared to treat the wastewater. The remains of aluminum were assayed by aluminon spectrophotography. The main factors, such as pH value ,flocculant use level, precipitation time and flocculate temperature were studied. The result showed that the remains ration of aluminum of PAZC is 7.2%, lower than that of PAC.
