摘　　要：利用NaClO作为化学氧化剂对二次处理过的皂素生产废水进行深度处理,研究了pH和NaClO的投加量、反应时间对皂素生产废水脱色率和COD去除率的影响。反应pH值是关键影响因素,分析了其作用机制。结果表明,实验最佳条件为:pH=6,反应时间30 min,NaClO投加量10 mL/100 mL。在最佳条件下,皂素生产废水COD去除率可达94.4%,脱色率为58.0%。The single factor experiments of saponin wastewater advanced treatment by cnemlcat oxzua- tion was conducted to investigate effect of pH, reaction time, NaCIO dosage on water decolorization and COD removal. The optimized treatment conditions were found out through orthogonal experiment. Results showed that pH was the key factor that affects the treatment efficiency; the optimize treatment conditions were pH 6, reaction time was 30 min, dosage of NaCIO was 10 mL/100 mL. Under these optimize conditions, decoloriza- tion rate and COD removal could reach to 94.4% and 58% respectively.
