摘要
利用统计学方法对臭氧氧化制药废水深度处理的影响因素进行了探讨和分析，考察了进水初始pH为7～11，臭氧流量为0．641g／h，反应时间为60-120min条件下，COD与色度去除率变化。采用Design—Expert6．0软件建立相应二次响应曲面模型，并对模型进行分析得出，当进水pH为8．14，臭氧流量为1g／h，反应时间为120rain时，COD与色度去除率最佳，分别为71．91％和96．75％。
In this paper, the impact ractors on the ozonation advanced treatment of pharmaceutical wastrwater were studied by statistics. Under the condition of initial influent pH varying from 7 to 11, ozone flow rate 0. 6 to 1 g/h, and reaction time from 60 to 120 minutes, the variances of COD and color reduction rates were studied. Using Design - Expert6. 0 software, the corresponding quadratic response surface model was built. Through the analysis of the model, it was found that when the pH was 8. 14, ozone flow rate 1 g/h, and reaction time 120 minutes, the COD and color reduction rates were the best, which were 71.91%and 96. 75%,respectively.
