摘　　要：以邯郸市滏阳河水为原水,进行臭氧/活性炭工艺深度处理微污染水源水的中试研究。中试采用混凝沉淀/Zeo-carbon生物滤池/臭氧/活性炭工艺,综合考察臭氧/活性炭对浊度、CODMn、UV254、NH 4+-N等指标的去除效果。结果表明,在该深度处理工艺中,臭氧的最佳投加量为2.0 mg/L,活性炭滤池的最佳滤速为6.0 m/h。在最佳运行工况下,出水浊度、CODMn、NH4+-N、UV254的平均值分别为0.85 NTU、2.43 mg/L、0.33 mg/L和0.031 cm-1,平均去除率分别为62.4%、53.5%、73.0%和59.4%,出水水质满足《生活饮用水卫生标准》(GB 5749—2006)的要求。Pilot study on treatment of micro-polluted source water from Fuyang River in Handan was conducted using the combined process of coagulation sedimentation, Zeo-carbon biofilter, ozone and GAC. The removal efficiencies of turbidity, CODMn, UV254 and NHf -N by O3/GAC as advanced treat- ment process were investigated. The results show that the optimal O3 dosage is 2.0 mg/L, and the optimal filtration velocity of activated carbon filter is 6.0 m/h. Under these conditions, the average turbidity, CODMn, NH4＋ - N and UV254 in the effluent from the advanced treatment process are 0.85 NTU, 2.43 mg/L, 0.33 mg/L and 0. 031 cm-1 respectively, and the average removal rates are 62.4%, 53.5%, 73.0% and 59.4% respectively, meeting the Standards for Drinking Water Quality （ GB 5749 - 2006）.
