摘　　要：蚊虫驱避剂(DEET)生产废水属高浓度有机废水。论文用三种方法(Fenton试剂氧化法、活性炭吸附法和二者组合法)对该种废水进行处理,寻找合适的处理方法,以达国家排放标准。处理效果显示,组合法效果最佳:用活性炭吸附,用量10g/L,在25℃条件下振荡60min;再用Fenton试剂氧化,FeSO4·7H2O的投加量为30g/L,H2O2溶液的投加量为40mL/L,在25℃条件下振荡80min,COD去除率为91.3%,可达国家三级排放标准。The bench-scale experimental study deals with the wastewater from production of DEET,a kind of mosquito repellent product（chemical name：N,N-diethyl-meta-toluamide）,and characterized with high organic strength and being refractory to treat.Two different methods such as Fenton process and adsorption by activated charcoal were used to treat the wastewater respectively,and then the combined treatment including activated charcoal adsorption followed by Fenton process.The combined treatment is proved to be the best choice and can meet the relevant permitted Grade Ⅲ in the national wastewater discharge standard（GB 8978-1996）under the optimum condition.
