摘　　要：由于制药废水经过两级生化处理后,可生化性差,水质成分复杂,总氮和悬浮物浓度高,采用臭氧氧化+AO-MBR+催化氧化联用工艺进行了深度处理,工程运行效果表明:该工艺具有良好的处理效果,抗冲击能力强,在进水COD_(Cr)为319.0~361.0 mg/L,总氮为45.0~60.0 mg/L,悬浮物为400.0~500.0 mg/L;出水COD_(Cr)稳定在32.0~45.0 mg/L,总氮稳定在8.6~14.0 mg/L,SS≤10.0 mg/L。出水指标优于《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准,可为此类废水处理提供参考。After two stages of biological treatment,the pharmaceutical wastewater has the characteristics of poor biodegradability,complex water components,and high concentrations of total nitrogen(TN) and suspended solids(SS).The operation results show that,used in advanced treatment,the combined process of ozone oxidation + AO-MBR + catalytic oxidation has the advantages of great effluence and strong impact resistance.With the influence of COD_(cr) 319.0~361.0 mg/L,TN 45.0~60.0 mg/L,and SS 400.0~500.0 mg/L,the effluence is able to reach to COD_(cr) 32.0~45.0 mg/L,TN 8.6~14.0 mg/L,and SS≤10.0 mg/L after treatment.The effluence meets the requirements of Pollutant Discharge Standard of Urban Sewage Treatment Plant(GB18918-2002) level A standard,which provides reference for this type of wastewater.
