摘　　要：采用O3-H2O2氧化法对印染废水进行氧化处理,比较了O3氧化法和O3-H2O2氧化法对印染废水的处理效果,考察了初始废水pH、H2O2加入量、O3流量和反应时间对废水的色度去除率和COD去除率的影响。实验结果表明:O3-H2O2氧化法对废水的COD和色度的去除效果比O3氧化法更好;在初始废水pH为11、H2O2加入量为13mmol/L、O3流量为6 g/h、反应时间为60 min的最佳工艺条件下,处理后废水COD为61.50 mg/L,COD去除率为95.73%,废水色度为5倍,色度去除率为99.75%,TOC为37.84 mg/L,TOC去除率为85.10%,BOD5为22.76 mg/L,BOD5去除率为90.20%,BOD5/COD为0.37。Dyeing wastewater was treated by O3-H2O2 oxidation process.The treatment effects of O3 oxidation process and O3-H2O2 oxidation process were compared with each other,and the factors affecting the removal rates of chroma and COD were studied.The experimental results show that：The effect of O3H2O2 oxidation process on removal of chroma and COD is better than that of O3 oxidation process;Under the optimum process conditions of initial wastewater pH 11,H2O2 dosage 13 mmol/L,O3 flow 6 g/h and reaction time 60 min,the COD is 61.50 mg/L with 95.73% of removal rate,the chroma is 5 times with 99.75% of removal rate,the TOC is 37.84 mg/L with 85.10% of removal rate,the BOD5 is 22.76 mg/L with 90.20% of removal rate,and the BOD5/COD is 0.37.
