摘要:本研究为提高臭氧（O3）氧化处理制浆中段废水的COD去除率，以广西某造纸厂制浆中段废水为研究对象，采用O3/H2O2组合工艺对其进行高级氧化处理。分别探究了废水初始pH值、O3用量、H2O2用量、反应时间和搅拌速度等影响因素对废水色度和COD去除效果的影响。为提高最优工艺参数的精确度，对O3/H2O2组合工艺参数进行响应面优化法分析。结果表明，在废水初始pH值=8、H2O2用量为1.0 mL/L、O3用量为480 mg/L的工艺条件下，废水色度为85.7倍，色度去除率为99.3%；CODCr达208.2 mg/L，CODCr去除率为84.5%。
Abstract:In this study， in order to improve the COD removal rate of ozone （O3） oxidation treatment of middle-stage pulping wastewater， a combined O3/H2O2 process was used for advanced oxidation treatment of middle-stage pulping wastewater from a paper mill in Guangxi. The effects of the initial pH value， O3 dosage， H2O2 dosage， reaction time， and stirring speed on the removal of colority and COD were investigated. To improve the accuracy of the optimal process parameters， the combined O3/H2O2 process parameters were analyzed by response surface optimization method. The results showed that under the process conditions of inital pH value=8， H2O2 dosage 1.0 mL/L， and O3 dosage 480 mg/L， the wastewater colority was 85.7 with removal rate of 99.3% and CODCr reached 208.2 mg/L with removal rate of 84.5%.
