摘　　要：针对工业区难降解制药废水的水质特点,通过臭氧/曝气生物滤池组合工艺进行一期工程生化池出水的深度处理。现场试验结果表明:先通过臭氧预处理提高废水的可生化性,然后再采用曝气生物滤池进行生化处理,可取得良好的处理效果。当臭氧投加量为24 mg/L、臭氧接触时间为1 h时,BOD5/COD的平均值由0.180提高到0.436。后续采用曝气生物滤池处理,当水力表面负荷为4.25 m3/(m2.h)、HRT为0.85 h时,出水COD<90 mg/L,稳定达到《污水综合排放标准》(GB 8978—1996)的一级标准。For the refractory pharmaceutical wastewater in industrial area, the combined process of ozone and BAF was used to treat the effluent of biochemical system. The results showed that good treat- ment effect could be achieved by preozonation to improve the biodegradability of wastewater and BAF for biological treatment. When the ozone dosage was 24 rag/L, and the contact time was 1 h during the preozonation, BODJCOD ratio was increased from 0. 180 to 0. 436. When the hydraulic surface loading was 4.25 m3/（m2 · h）, and HRT was 0.85 h in the subsequent treatment by BAF, the average effluent COD was less than 90 mg/L. The effluent of ozone/BAF process met the first class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）.
