摘　　要：以配制的活性艳蓝P-3R染料废水为研究对象,研究了复合氧化法O3/H2O2降解染料活性艳蓝P-3R的效果,并分析了反应时间、H2O2投加量、H2O2投加方式、pH值等各种因素对处理效果的影响。结果表明:O3/H2O2比单独O3反应的效果要好;反应时间越长,脱色率和TOC去除率也越大;H2O2投加量对氧化反应的影响很大,存在一个最佳投加量;总量相同的H2O2一次投加优于多次投加;pH值越大,去除率也越大;Na2CO3作为自由基清除剂在一定程度上抑制了O3/H2O2氧化。The Reactive Blue P-3R wastewater is degraded in this reserach by compound oxidation of O3/H2O2. The research indicates., the effect of O3/H2O2 is better than that of the separate O3 reaction; the reaction time is longer,the decolorization rate and TOC removal rate are greater; the H2O2 dosage have a great influence on the oxidation reaction and there is an optimal dosage; the same total amount of H2O2 once dosing is better than multiple dosing;the pH value is larger, the removal rate is greater; as free radical scavenger, Na2CO3 inhibits the oxidation of O3/ H2O2 to some extent.
