摘　　要：焦化厂污水中含有大量油类、酚氰和氨氮等污染物。介绍采用气浮、A/O(厌氧/好氧)生物脱氮工艺处理焦化厂酚氰污水的流程,各阶段的设计、运行参数。设计处理能力为65 m3/h。目前系统运行稳定,出水各项指标达到国家GB 8978—1996《污水综合排放标准》中二级排放标准。There are plenty of pollutants, such as oils, phenol-cyanogen, ammonia nitrogen, etc, in coking waste water. It is introduced flow sheet, design ＆ running parameter ol air floatation and A/O （anaerobic / aerobic） bio-denitrification process for treatment of sewage from a coking plant. The design treatment capacity of the process was 65 m3/h. At present, the system runs steady, the treated water quality reachs scondary discharge standard of ＂Integrated Wastewater Discharge Standard＂ （GB 8978--1996）.
