摘　　要：制药废水成分复杂,色度大、COD浓度高、可生化性差,属于难生物降解有机废水。采用微电解-芬顿-EGSB-A/O-生物接触氧化-BAF-混凝工艺进行处理,运行结果表明,该工艺处理效率高,抗冲击负荷能力强,对COD、NH_3-N、TP的去除率分别可达到99.9%、88%和99.5%,最终出水COD、NH3-N、TP分别为85.8、15.0、0.4 mg/L,达到《污水综合排放标准》(GB8978—1996)的一级标准。Pharmaceutical wastewater is a refractory organic wastewater due to its complicated composition, high chromaticity, high COD concentration and poor biodegradability. The combined process including micro-electrolysis, Fenton, EGSB, A/O, biological contact oxidation, BAF and coagulation was applied to treat this type of wastewater. The results indicate that the combined process has high treatment performance and strong resistance to shock loading. The final effluent concentrations of COD, NH3 -N and TP were 85.8, 15.0, 0.4 mg/L with the remove efficiency of 99.9%, 88% and 99.5% respectively. The effluent quality could meet the first class of Integrated Wastewater Discharge Standard （ GB 8978 - 1996）.
