摘　　要：采用混凝气浮—臭氧氧化/活性炭吸附组合工艺深度处理兰州石化分公司化工外排污水,考察了主要操作参数并确定了最佳工艺条件。试验表明,该处理技术能将COD在60～100 mg/L的化工外排污水COD去除50%～80%,出水COD≤35 mg/L,稳定达到《污水综合排放标准》(GB/T 8978—1996)的一级排放标准。The combined process, coagulation air flotation-ozone oxidation/activated carbon adsorption, has been applied to the advanced treatment of chemical outward-discharged wastewater from Lanzhou Petrochemical Co. The main operation parameters are investigated and its optimal processing conditions are ascertained. The experimental results show that 50%-80% of the COD can be removed from the chemical outward-discharged wastewater whose COD was 60-100 mg/L. Its effluent COD is ≤ 35 mg/L, steadily reaching the first class of Integrated Wastewater Discharge Standard （GB/T 8978-- 1996 ）.
