摘　　要：臭氧催化氧化-曝气生物滤池(O3-BAF)组合工艺可深度处理炼化含盐污水。中海石油炼化有限责任公司惠州炼化分公司对含盐二级生化出水采用O3-BAF组合工艺进行了深度处理改造,并研究了将曝气生物滤池(BAF)前置的曝气生物滤池-臭氧催化氧化(BAF-O3)组合工艺。运行结果显示:BAF单元前置后,其化学需氧量(COD)去除率提高,COD去除量由2.71 mg/L提高至11.53 mg/L,且由于对悬浮物的过滤,有利于保护后续的臭氧催化氧化单元。Ozone Catalytic Oxidation- Biological Aerated Filter（ O3- BAF） combined process can be used for deep treatment of saline sewage from refining process. CNOOC Huizhou Refinery Branchadopted O3- BAF combined process for deep treatment of its saline secondary biological effluent,and studied the Biological Aerated Filter- Ozone Catalytic Oxidation（ BAF- O3） combined process which preposed the Biological Aerated Filter（ BAF）. The result showed that after preposing of BAF unit,the COD removal rate increased,and the removing volume increased from 2. 71 mg / L to 11. 53 mg / L. In addition,filtration of suspended solids was helpful for protection of the downstream ozone catalytic oxidation unit.
