采用A^2／O-臭氧氧化．活性炭过滤的组合工艺对焦化废水进行处理，以解决其达标排放。进水COD1267mg／L，NH3-N113mg／L，SS150mg/L左右时．工艺对COD、氨氮、SS的去除率分剐达到93％、95％、95％，出水满足《污水综合排放标准》（GB8978-1996）一级标准。试验结果零明该工艺对焦化摩水有很好的咎理罄果。%A^2/O-ozone oxidation-activated carbon filter treatment for coking wastewater was studied to solve substandard discharge. When influent COD was 1267 mg/L, influent NH3＋N was 113 mg/L, influent SS was 150 mg/L, the removal efficiency of the three were 93 %, 95 %, 95 % respectively. Effluent was up to the ＂Comprehensive sewage discharge standard＂（GB8978-1996）. Results showed that coking wastewater could be well treated using this process.
