摘　　要：针对某制药工业园区综合废水污染物成分复杂、难降解、毒性大、色度深等特点,提出了水解酸化/好氧-臭氧-曝气生物滤池(H/O-O3-BAF)的工艺流程。通过现场实验研究对处理流程以及各个处理单元的运行参数进行了优化。系统稳定运行期间,处理出水化学需氧量(COD)小于50 mg/L,色度小于4倍,出水水质达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级A标准。发光菌毒性的测试表明,该工艺流程可有效削减废水中的生物毒性。The wastewater of pharmaceutical industrial park characterized by complicated components, hard degradation and high toxicity and colority, was treated using a combined process of hydrolysis acidification/aero- bic-ozone oxidation-biological aerated filter（H/O-O3-BAF）. The treatment process and operation parameters of all units were optimized through field test. During stable operation of this system,the effluent chemical oxygen demand（COD） and colority could be below 50 mg/L and 4 times, respectively. The water quality of the effluent can meet the first-rate quality regulated by the Discharge Standard for Municipal Sewage Treatment Plant （GB18918-2002）. The results of luminescent bacteria toxicity test revealed that the biotoxicity of wastewater could be reduced efficiently by the combined process.
