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pH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.
為提高單獨聚閤氯化鋁(PAC )混凝處理效果,以贛南某水庫水為原水,攷察瞭高錳痠鹽複閤藥劑(PPC)預氧化對原水的彊化混凝效果. 結果錶明,在初始pH值為7~8、PPC 投加量為1.8 mg/L、 預氧化時間為4 min時,PPC預氧化對原水錳、 氨氮的去除率分彆為 (70.21±0.31)%、(49.72±1.56)%,較單獨PAC混凝分彆提高瞭34.32%和9.62%,可提高飲用水水質安全性.

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.
