以某精细化工企业废水处理工程为例，介绍了"物化-混凝-厌氧氧化-水解酸化-两级接触氧化—MBR生化处理工艺"处理精细化工废水的工程应用案例，对工程设计及运行经验方面进行分析总结；设计处理水量为600 m³/d，运行结果表明，综合污水COD_Cr、NH₃-N、SS的去除率分别达到97.8%、79.2%、90.6%。出水口各项指标均可满足GB 8978—1996《污水综合排放标准》中的一级排放标准。

Taking the wastewater treatment plant of a fine chemical enterprise as an example,this paper introduces an engineering application case using "physicochemical-coagulation-anaerobic oxidation-hydrolysis acidification-two-stage contact oxidation-MBR biochemical treatment process" to treat fine chemical wastewater.The engineering design and operation experiences are analyzed and summarized.The designed treatment water volume of the plant is 600 m³ per day.The running results show that the removal rates of COD_Cr,NH³-N and SS are 97.8%,79.2% and 90.6%,respectively.The effluent water quality meets the first class of the Integrated Wastewater Discharge Standard (GB 8978-1996).
