摘　　要：研究了化学氧化法处理黄姜皂素废水生化处理出水的脱色效果,考察氧化剂种类、投加量、pH值及接触氧化时间对脱色效果的影响。结果表明:常温时处理后出水色度指标均可达到国家行业标准,且最佳条件下次氯酸钠较双氧水具有更好的脱色效果,次氯酸钠处理成本也相对较低。The decolorization effect of biochemical treatment effluent of the sapogenin wastewater by chemical oxidation. The impact of the type of oxidant, the oxidant＇s dosage, pH and the contact oxidation time on the decolorization effect has also been investigated. The experimental rcsuhs showed that the color index of the treated wastewater all met the national industrial standard at normal temperature. And at the optimum conditions, sodium hypochlorite gave better color removal effect than hydrogen peroxide with lower processing cost.
