摘要
为有效地处理含TNT炸药的废水,研究了Fenton氧化对其的处理效果。通过正交实验考察各因素对反应的影响,结合单因素实验确定了最佳反应条件。结果表明,Fe2+与H2O2的摩尔比对溶液中CODcr去除率影响最大,pH值对反应也有一定影响,H2O2与CODcr投加质量比的影响则较小;最适反应条件为H2O2与CODcr投加质量比为1,Fe2+与H2O2投加摩尔比为6,反应pH值为6,反应时间为60min;在最佳反应条件下,CODcr去除率可高达95.1%,出水CODcr质量浓度为13.4mg/L。
In order to treat wastewater containing TNT effectively, the effect of treating the wastewater with Fenton oxidation is studied. The results of orthogonal and single-factor experiments suggested that： the n（Fe^2＋）/n（H2O2） ratio influences the removalrate of CODer in the wasterwater mostly, pH value has some influence, while the m （H2O2）/m （CODcr） ratio has little influence. The optimum Fenton Oxidation conditions obtained from the experimental results were m （H2O2）/m （CODer） = 1, n （Fe^2＋ ）/n （H2O2） = 6, pH = 6, and reaction time 60min. Under the optimum reaction conditions, the highest removal rates of CODer was 95. 1%, and the efflunet concentration of CODer was 13.4mg/L.
