摘　　要：为提高单独聚合氯化铝（PAC）混凝处理效果,以赣南某水库水为原水,考察了高锰酸盐复合药剂（PPC）预氧化对原水的强化混凝效果.结果表明,在初始p H值为7～8、PPC投加量为1.8 mg/L、预氧化时间为4 min时,PPC预氧化对原水锰、氨氮的去除率分别为（70.21±0.31）%、（49.72±1.56）%,较单独PAC混凝分别提高了34.32%和9.62%,可提高饮用水水质安全性.In the experiment, pre-oxidation coagulation sedimentation process was proposed to treat micro-polluted water in a reservoir in Gannan areas. The results show that under the conditions of pre-oxidated time 4 min, pH 7～8, the dosage of PPC is 1.8 mg/L, the removal rate of ammonia and manganese are （49.72±1.56）%, （70.21±0.31）%, respectively . Compared with single coagulation performance of PAC, the removal rate of PPC pre-oxidation process has improved by 9.62 % and 34.32 % respectively. The pre-oxidation plays a more important role in enhancing coagulation and improving the security quality of drinking water.
