摘　　要：采用Fenton氧化和光助Fenton氧化对黑索今回收过程废水处理进行研究,考察了FeSO4浓度、H2O2浓度、pH、反应时间和反应温度等因素对处理过程的影响规律。结果表明:FeSO4浓度和废水的pH值都存在最佳值,分别为FeSO4700 mg/L和pH 2.5;COD去除率随着H2O2浓度增大而增大,随温度的升高而降低;5 min反应基本完成;当H2O2浓度为100 mg/L、反应温度为15℃时,COD去除率可达82.07%.在光助Fenton下,FeSO4的适宜浓度降低为50 mg/L.Fenton process and photo-Fenton process were employed to treat the wastewater formed during the recovery of RDX. The effects of Fe2SO4 dosage, H2O2 dosage, pH, reaction time and temperature on removal efficiency of chemical oxygen demand （COD） the wastewater were investigated. The results show that the optimum FeSO4 dosage and pH value are 700 mg/L and 2.5, respectively, and that the COD removal efficiency of the wastewater increases with the rise of H2O2 dosage but decreases with the rise of temperature. Under the conditions with H2O2 dosage of 100 mg/L and the reaction temperature of 15 ℃, the best removal efficiency of COD is obtained at 82.07 %. In the photo- Fenton process, FeSO4 dosage could be reduced sharply to 50 mg/L.
