摘　　要：采用臭氧氧化-生物接触氧化工艺处理黑臭水。考察了臭氧投加量、p H在臭氧氧化阶段对COD的影响,p H在生物接触氧化阶段对COD和NH3-N的去除效果,得到了各单元的最佳反应条件。在臭氧投加量为90~150mg/L,黑臭水p H为7~8情况下,黑臭水经过臭氧氧化-生物接触氧化工艺处理后,出水的平均COD为42.8 mg/L,氨氮的平均质量浓度为3.9 mg/L,达到污水综合排放标准(GB 8978-1996)一级标准。Ozonation and biological contact oxidation process was used to treat black and odorous water. The effects of ozone dosage and pH in ozonation stage on COD removal and the effect of pH in biological contact oxidation stage on COD and ammonia nitrogen （NH3-N） removal efficiency were investigated. The optimum reaction conditions of each unit were obtained. When the ozone dosage was 90- 150 mg/L, black odorous water pH was 7-8, the average mass concentration Of effluent COD and NH3-N were 42.8 mg/L and 3.9 mg/L, respectively, after black odorous water treated by ozone oxidation biological contact oxidation process, the effluent reached the first level standard of sewage comprehensive discharge standard （GB 8978-1996）.
