摘　　要：经过生化处理的驱油污水中仍含有大量的难降解有机物,本研究采用臭氧催化氧化对驱油污水进行深度处理,考察初始p H值、反应时间、臭氧浓度等对驱油污水处理效果的影响。结果表明:当进水COD为100 mg·L^(-1),p H值为9,反应时间为60 min,臭氧浓度为12 mg·L^(-1)时,采用掺杂型纳米Mn O_2/Al_2O_3作为催化剂(70 mg·L^(-1)),COD去除率大于55%,出水满足《污水综合排放标准》(GB 8978^(-1)996)中的一级A标准。催化剂使用前后,比表面积、孔结构等均未发生明显变化,未出现新的晶相,催化剂未发生失活现象。A large amounts of refractory organics were remained in oil flooding wastewater after the secondary biological treatment. The oil flooding wastewater was treated using catalytic ozonation technology in this study. The effects of initial pH, reaction time and ozone concentration on the treatment performance of driving oil wastewater were investigated. The results showed that when the influent COD concentration, the pH value, the reaction time and the ozone concentration were 100 mg ·L^-1, 9, 60 min and 12 mg ·L^-1, respectively, the COD removal efficiency was higher than 55% and the effluent could meet the ＂integrated Wastewater Discharge Standard＂ （GB 8978-1996） by using the doped nano MnO2/Al2O3 catalyst （the catalyst dosage of 70 mg ·L^-1）. The specific surface area and pore structure didn＇t change significantly after and before the catalyst was used. Meanwhile, new crystalline phase didn＇t appeare and the catalyst deactivation didn＇t happen.
