摘　　要：DMBA生产废水成分复杂,有机物浓度高,属于难处理的化工废水。在处理规模为80 m^3/d的工程中,设计采用预处理/UASB/延时曝气/混凝沉淀组合工艺,经调试及试运行验收,出水水质满足《污水综合排放标准》(GB 8978—1996)的三级标准,达到工业区污水管网接管要求。The dimethlolbutyric acid （DMBA） production wastewater characterized by complicated pollutants and high eontent of organics, is diffieult to be treated. The combined process of pretreatment/ UASB/extended aeration-coagulating sedimentation was adopted to treat the DMBA wastewater with ca- pacity of 80 m3/d. After the project commissioning and acceptance, the effluent quality meets the third grade standards speeified in Integrated Wastewater Discharge Standard（ GB 8978 - 1996）. So the effluent could be diseharged into the industrial sewage pipe network.
