摘　　要：采用催化臭氧氧化工艺深度处理维生素B12废水生化处理出水中残留难降解COD。实验原水为维生素B12经厌氧反应器处理的出水，对原水进行好氧生化批处理实验，模拟二级处理脱碳除氮，其出水进入催化臭氧氧化装置。催化臭氧装置中装填活性氧化铝载体催化剂，曝气量为0．15kg／m3，反应30min后污水即可脱色；反应1h后，COD浓度降至120mg／L以下，COD去除率达78％，可满足达标排放要求。催化臭氧氧化工艺深度处理维生素B12废水可行且经济。The anaerobic bio-treated Vitamin B12 wastewater was advanced treated by catalytic ozone oxidation following aerobic treatment. After aerobic batch bio-treatment, the influent was aerated in the catalytic ozone oxidation equipment with ozone dosage of 0.15kg/m3. Half an hour later, the chromaticity was well removed and an hour later, the COD concentration reduced to 120 mg/L with COD removal rate of 78%. Catalytic ozone oxidation is feasible and economic on advanced treatment of Vitamin B12 wastewater.
