摘　　要：以黄姜皂素废水为研究对象,采用Fenton试剂深度氧化技术进行降解处理。研究结果表明,原水COD的质量浓度为34676mg/L,色度为3500倍,浊度为475NTU,在Fe2+投加量为2.92g/L(绿矾14.48g/L),H2O2投加量为70g/L,pH值为1左右,反应时间0.5h的最佳条件下,COD、色度、浊度去除率分别达到91.15%、95.71%、94.74%。通过甲基紫-分光光度法测定羟基自由基浓度,为最佳反应条件的确定提供了理论依据。此方法具有反应时间短(0.5h),无需调节pH值,不受SO42-浓度影响,不产生二次污染等特点。The treatment of dioscorea zingoberenisi C.H. wright saponin wastewater by fenton reagent with advanced oxidation process was investigated. The results showed that, when the COD, colority, turbidity of the original wastewater were 34 676 mg/L, 3 500 times, 475 NTU respectively, under the optimal condition that the dosage of Fe^2＋ was 2.92 g/L（copperas was 14.48 g/L ）, the dosage of H2O2 was 70 g/L, the pH value was about 1, the reaction time was 0.5 h, the removal rate of COD, colority and turbidity reached 91.15%, 95.71% and 94.74% respectively. The concentration of hydroxyl radical had been determined by methyl violet spectrophotometry, which gave a theory basis for the determination of optimal operating conditions. The technique has characteristics of short reaction time, no need to adjust the pH, not affected by SO4^2- concentration, no secondary pollution and so on .
