摘　　要：医药化工废水BOD5和COD浓度高,盐度高,难生物降解。采用微电解-Fenton-气浮-A/O工艺处理医药化工废水,处理量为300 m3/d,废水COD为8 000～11 000 mg/L,盐分为16 000～21 000 mg/L。运行实践表明,物化/生化协同处理医药化工废水效果显著,对COD的去除率达到94%,出水COD <500 mg/L,对盐分的去除率达到85. 6%,水质指标达到《污水综合排放标准》(GB 8978—1996)的三级纳管标准。Pharmaceutical and chemical wastewater is characterized by high concentration of BOD5 and COD, high salinity and difficult biodegradation. The combined process of micro-electrolysis, Fenton, air floatation, and A/O is adopted, with the treating capacity of 300 m^3/d. The concentration of influent COD is 8 000 - 11 000 mg/L, and the concentration of influent salinity is 16 000 - 21 000 mg/L. The operation results showed remarkable effect of physicochemical/biochemical synergistic treatment process for the pharmaceutical and chemical wastewater. The COD removal efficiency reached 94% with the effluent concentration of COD less than 500 mg/L, and the salinity removal efficiency reached 85.6% after bio-treatment. All the quality indexes of treated water reach the third level of Integrated Wastewater Discharge Standard（ GB 8978 -1996）.
