摘　　要：湖北某牛磺酸生产企业废水处理工程,从企业生产工艺和废水水质特点出发,有针对性地采用“水解酸化+前缺氧+好氧生化+后缺氧+二沉”工艺处理该企业生产废水。进水平均COD、氨氮、总氮分别为956.8、50.6、99.1mg/L时,出水平均COD、氨氮、总氮分别为73.6、1.6、12.2 mg/L,COD、氨氮、总氮平均去除率可分别达到92.3%、96.9%、87.7%,出水水质稳定,达到《化学合成类制药工业水污染物排放标准》(GB 21904—2008)中新建企业水污染物排放浓度限值。采用渐减曝气和风机变频控制,能耗显著降低,单位水量运行费用为1.60元/m~3。With the wastewater treatment project of a taurine production enterprise in Hubei as a case study,this paper analyzed the production process and wastewater quality characteristics of the enterprise,the targeted treatment process of “hydrolysis acidification+pre anoxic+aerobic biochemistry+post anoxic+secondary sedimentation” was adopted.When the average influent COD,ammonia nitrogen,and total nitrogen were 956.8,50.6,99.1 mg/L,respectively,the average effluent COD,ammonia nitrogen,and TN were 73.6,1.6,12.2 mg/L,respectively,with the average removal rates could reach 92.3%,96.9%,and 87.7%,respectively.The effluent water quality was stable and meet the limits of water pollutants for newly built enterprises in the Chemical Synthesis Pharmaceutical Industry Water Pollutant Discharge Standard(GB 21904-2008).By adopting tapered aeration and fan frequency conversion control,energy consumption was significantly reduced,and the operating cost was 1.60 CNY/m~3.
