采用两级臭氧-活性炭组合工艺在以太湖水为水源的某水厂进行深度处理中试研究.结果表明:该组合处理工艺对有机污染物有稳定的去除效果,在预臭氧投加重为0.5 mg/L、主臭氧投加量为0.7 mg/L下,相对于原水对CODMn,UV254(紫外吸光度),DOC,THMEP,氨氮,亚硝酸盐氮和硝酸盐氨的平均去除率分别为47.06％,80％,31.92％,58.9％,65.5％,81.25％和9.1％,出永满足GB 5749-2006《生活饮用水卫生标准》的要求,炭滤池出水中臭氧消毒副产物均低于标准限值,组合工艺对有害物质冲击负荷有一定的抵抗能力.%The pilot experiments were carried out to investigate the advanced treatment by the combined process of two-stage ozonization and activated carbon in a plant using Taihu Lake water as raw water. The results showed that the removal of organic pollutants by the combined process was stable. Relative to the raw water, the average removal rates of CODmns UV254, DOC, THMEP, ammonia nitrogen, nitrite nitrogen and nitrate nitrogen were 47.06%, 80%, 31.92%, 58.9%, 65.3%, 81.25% and 9.1% respectively, when the pre-ozonizaiton dosage was 0.5mg/L and the main ozonization dosage was 0.7mg/L. The effluent could meet "Standards of Drinking Water Quality "(GB 5749-2006). The disinfection by-products of ozone were lower than the standard limit in the effluent from carbon filter. The combined process has some resistibility to the impact load of hazardous substances.
