摘要
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CODCr、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 CODCr,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).
