摘　　要：采用O3/H2O2氧化工艺深度处理制药废水二级生化出水,探讨了废水初始pH、H2O2投加量、O3投加量等因素对O3/H2O2氧化工艺的影响,确定了O3/H2O2氧化技术处理制药废水的最佳操作条件。结果表明,制药废水二级出水COD在480 mg/L左右时,pH为9,进臭氧质量浓度为1 247 mg/(L.h),处理时间为4.5h,COD去除率可达83%,B/C(BOD5/COD)从初始的0.007提升到0.32,较原水增高了46倍,大大提高了制药废水的生化性能,便于后续的生物处理。The secondary effluent of pharmaceutical wastewater was treated by O3/H2O2 process in this study. TheeffectsofinitialwastewaterpHandO3 dosage as well as addition of hydrogen peroxide on ozonation process were investigated to determine the optimal operation parameters. It showed that COD removal effieiencies could reach 83% under the condition of initial pH=9, 03 dosage 1 247 mg/（L-h）at the end of 4.5 h. The BODJCOD ratio （B/C ratio） increased from 0.007 to 0.32 with a B/C ratio increasing by 46 times. O3/H2O2 process could enhance biodegradability of pharmaceutical wastewater due to improving biochemical properties.
