摘要
采用H2O2催化臭氧氧化深度处理垃圾渗滤液,考察了臭氧通量、H2O2投加量以及反应时间对COD去除率的影响。响应面实验结果表明,各因素对COD去除率有显著影响,影响顺序:臭氧通量>反应时间>H2O2投加量;所得模型可较好地反映真实的处理过程;通过模型最优化分析得到最佳反应条件:臭氧通量3.86 g/h,H2O2投加量51.54 mmol/L,反应时间41.12 min,此条件下COD去除率的预测值为84.81%。
The H_2O_2 catalytic ozonation process has been used for the advanced treatment of landfill leachate,and the influences of ozone flux,H_2O_2 dosage and reaction time on the removing rate of COD are investigated. The experimental results of response surface methodology show that every factor alone has significantly influence on the COD removing rate. The sequence of influences is ozone flux〉reaction time〉H2O2 dosage. The model obtained could greatly respond the real treatment process. The optimal reaction conditions obtained from the optimization analysis of the model are as follows:the ozone flux is 3.86 g/h,H2O2 dosage 51.54 mmol/L,and reaction time 41.12 min. Under these conditions,the highest predicted value of the COD removing rate is 84.81%.
