摘　　要：采用O_3/NaClO协同高级氧化技术对校园屋面雨水COD、氨氮去除效果及最佳反应条件进行了实验研究,并与O_3单独氧化进行了对比.试验结果表明:O_3单独氧化最佳pH值为10,最佳反应时间为20 min,原水中COD和氨氮的去除率分别达到77.95%,60.54%;O_3/NaClO协同氧化最佳反应时间为30 min,最佳pH为7,雨水中COD、氨氮的去除率分别为87.45%,82.83%.COD和氨氮含量分别符合《地表水环境质量标准》(GB3838-2002)Ⅰ类和Ⅱ类的水质指标要求.Advanced O3/NaClO collaborative oxidation is used to remove COD and ammonia-nitrogen treating school roof rainwater to research the removal effectiveness and the optimal reaction conditions. It is also compared with the individual O3 oxidation treating process. The experimental result shows that the optimal reaction conditions of individual 03 oxidation are： The optimum reaction time is 20 minnutes and pH=1 0, with the removal rate of COD and ammonia-nitrogen respectively reaching up to 77.95%, 60.54%; at the same time, the optimal reaction conditions of O3/NaClO oxidation process are： The optimum reaction time is 30mins and pH=7, with the removal rate of the rainwater COD and ammonianitrogen respectively reaching up to 87.45%, 82.83%. After the treating, the concentrations of ammonia-nitrogen and COD both have reached the requirement of Environmental Quality Standards of the water quality Ⅰ and Ⅱfor Surface Water （GB3838-2002）.
