摘　　要：研究了高铁酸盐原液单独使用及与聚合氯化铝(PAC)联用处理城市生活污水的效果。研究结果表明：高铁酸盐与PAC联用的效果更好,对生活污水的COD_(?)、氨氮、磷、SS和细菌等具有良好的去除能力。投加4mg／L的高铁酸盐和40mg／L PAC时,出水中COD_(?)、氨氮、磷、SS均已达到城镇污水处理厂污水排放二级标准(GBl8918-2002),且细菌的去除率可达到99．9％。为城市生活污水化学强化一级处理提供了有价值的参考依据。The effect of the situation of adding crude solution of fenate （Ⅵ） alone and the situation of adding crude solution of ferrate（Ⅵ） combined with PAC on the treatment of domestic sewage were studied. The results indicated that the puriticafion effect of adding crude solution of ferrate （Ⅵ） together with PAC was better for removal of CODCr ammonia nitrogen, phosphorus, SS and bacterium than that of adding crude solution of ferrate （Ⅵ） alone. When 4 mg/L ferrate（Ⅵ） and 40 mg/L PAC were added together, removal rate of CODCr ammonia nitrogen, phoshorus and SS met the requirements of the discharge standard of pollutants for municipal wastewater standard of pollutants for municipal wastewater treatment plant （GB 18918-2002） and the removal rate of bacterium was 99.9%. Meanwhile, the results were valuable reference to the application prospect in chemically enhanced primary treatment （CEPT） on domestic sewage treatment.
