摘　　要：S-诱抗素生产过程中产生的废水COD Cr浓度高、含难降解大分子物质、冲击负荷高、可生化性差,采用预处理-两级UASB-接触氧化法组合工艺处理取得了良好的效果。工程实践表明,废水中COD Cr、NH3-N的去除率分别达99.9%、99.6%,出水可稳定达到《污水综合排放标准》(GB8978-1996)一级排放标准,处理效果良好。The wastewater discharged from the S-Abscisic acid production contains high concentrations of COD Cr and harddegradation macromolecules. The shock load of the wastewater was high,so it had low biodegradability. Using pretreatment- two stage UASB-contact oxidation combined process achieved good results. Engineering practice showed that the removal rate of COD Cr and NH 3-N were 99. 9% and 99. 6% respectively. The effluent water quality can meet the Class A of Integrated Wastewater Discharge Standard( GB8978-1996). The process has good treatment effect.
