| 摘 要： | 为了提高含高嘧啶类制药废水的可生化性能并在一定程度上降低该废水的COD,采用臭氧氧化法对该废水进行预处理研究。采用正交试验考察了pH值、H2O2和反应时间及三种因素两两交互作用对臭氧氧化嘧啶类废水COD去除的影响。结果表明:H2O2的剂量对嘧啶废水COD去除率的影响高度显著;其次为停留时间,pH值和三种因素的两两交互作用影响不显著。在90min内O3将嘧啶废水的BOD5/COD由0.11提高至0.36。氧化时间过长,会使易降解有机物进一步氧化,可生化性降低。

| Abstract: | In order to improve biodegradability and decrease COD of the pharmaceutical wastewater, Ozonization process was adopted. The effect of catalyst H2O2 ,pH, the hydraulic retention time(T) and the interactions of the three factors were studied with orthogonal experimental study. The conclusion was that H2O2 was highly markedly to removal COD, the reaction time(t) was remarkable, and pH and the effect of the interactions of the three factors were not remarkable. O3 oxidation increased the pharmaceutical wastewater bio-degradable ability, and increased the rate of BOD5 to COD from 0.11 to 0.36. However, the bio-degradable ability decreased with prolonging the retention time of O3. |
