摘　　要：采用非均相催化臭氧氧化工艺深度处理化工废水二级生化出水,探索负载不同活性组分的活性炭催化剂及该工艺处理化工废水的影响因素。结果表明：当进水COD为85~110 mg/L,臭氧投加量为60 mg/L,催化剂投加量为200 mg/L Cr时,臭氧氧化、ACCA-1、ACCA-2和ACCA-3催化臭氧氧化对出水COD的平均去除率分别为22.46%、32.7%、40.5%和35.7%,3种催化剂均可强化臭氧氧化效果。活性炭催化剂能提高臭氧利用率,叔丁醇对ACCA-2抑制效果最明显。In this paper, heterogeneous catalytic ozonation oxidation was applied in advanced treatment of the secondary effluent of chemical industrial wastewater. Different activated carbon catalytic supported metallic oxide and influencing factors were investigated. The results showed that when CODCr of the influent was 85~110 mg/L, ozone dose was 60 mg/L and catalyst dose was 200 mg/L, the average removal efficiency of COD in the effluent by such four advanced treatment technologies as catalytic ozonation, ACCA-1, ACCA-2 and ACCA-3 was 22.46%, 32.7%, 40.5% and 35.7% respectively, indicating that catalyst could strengthen the effects of ozone oxidation. Active carbon catalysts could improve the ozone utilization rate, and tert butyl alcohol inhibited the effects of ozone oxidation remarkably, especially for ACCA-2.
