摘　　要：分别采用强化混凝和强化混凝—UV/H2O2/微曝气联合工艺处理污染水.混凝剂采用聚合氯化铝(PAC)、聚合硫酸铁(PFS)、聚合氯化铝铁(PAFC)进行强化混凝处理,PAC混凝剂对色度和浊度有较好的去除效果,在投加量为40 mg/L时,色度和浊度的去除率可达92.2%、97.5%,出水达到饮用水标准GB 5749-2006;CODMn可去除65.57%,但氨氮的去除率较低.强化混凝—UV/H2O2/微曝气工艺,对CODMn去除效果明显,氧化40 min去除率达86.9%,且出水达到饮用水标准,但对氨氮的去除效果不明显.The enhanced coagulation process and enhanced coagulation-UV/H2O2/mico-aeration process are respectively adopted to treat the water from polluted source. The coagulant includes Poly Aluminum Chloride （ PAC）, Polymeric Ferric Sulfate （PFS） and Polymeric Aluminum Ferric Chloride （ PAFC）. PAC coagulant has a better effect in removing the color chroma and turbidity than the others. With a dosage of 40 mg / L, the chroma removal can be as high as 92.2 %, and turbidity removal 97.5 %. The treated water came up to the drinking water standard GB 5749-2006 ; CODMn can be removed 65.57 %, but the ammonia nitrogen removal rate is lower. Enhanced coagulation-UV/H2O2/ micro-aeration process has a better removal effect on CODMn, with the removal rate being 86.9 % after a 40-minute treatment, and the treated water came up to the drinking water standards. The effect of ammonia removal was not obvious.
