摘　　要：采用铁碳微电解/上流式厌氧污泥床/水解酸化/接触氧化/曝气生物滤池/絮凝沉淀工艺处理某化学研究所特种化工废水,处理规模为500 m^3/d。工程运行结果表明,该工艺处理效率高,最终出水COD、总氮、氨氮和SS分别低于15、9、0. 8和2 mg/L,达到允许排放标准。The combined process of Fe/C microelectrolysis, upflow anaerobic sludge blanket, hy- drolysis, contact oxidation, biological aerated filter and flocculation sedimentation was used to treat spe- cial chemical industry wastewater with a treatment capacity of 500 m3/d. The results showed that the process had high treatment efficiency, and the final effluent chemical oxygen demand, total nitrogen, am- monia nitrogen, and SS were less than 15 mg/L, 9 mg/L, 0.8 mg/L, and 2 mg/L, respectively, which met the allowable discharge standard.
