Fenton氧化和光助Fenton氧化处理黑索今回收过程废水

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FeS04浓度、H202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：FeS04浓度和废水的pH值都存在最佳值，分别为FeS04 700 mg/L和pH 2.5；COD去除率随着H202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H2 02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，FeS04的适宜浓度降低为50 mg/L.

Treatment of Wastewater of Recovery RDX by Fenton and Photo-Fenton Process

Fenton process and photo-Fenton process were employed to treat the wastewater formed during the recovery of RDX. The effects of Fe2S〇4 dosage, H2O2 dosage, pH, reaction time and tem?perature on removal efficiency of chemical oxygen demand (COD) the wastewater were investigated. The results show that the optimum FeS〇4 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 de-creases with the rise of temperature. Under the conditions with H2O2 dosage of 100 mg/L and the re?action temperature of 15℃，the best removal efficiency of COD is obtained at 82.07% . In the photo- Fenton process, FeS〇4 dosage could be reduced sharply to 50 mg/L.
