摘　　要：针对规模化养殖场养殖废水传统脱氮处理工艺脱氮效率低、运行费用高等技术问题,文章提出养殖废水的亚硝化-厌氧氨氧化脱氮处理工艺,并开展示范工程研究。研究结果表明:亚硝化-厌氧氨氧化工艺在养殖废水处理过程中运行稳定,工艺出水中氨氮(NH_(4)^(+)-N)、化学需氧量(chemical oxygen demand,COD)、悬浮固体(suspended solids,SS)、总氮(total nitrogen,TN)的平均质量浓度分别为34、58、190、127 mg/L,平均去除率分别为82.5%、81.7%、91.6%、58.3%,出水水质满足《畜禽养殖业污染物排放标准》GB 18596—2001的要求。该工艺的废水处理总成本为2.83元/m^(3),与其他的生物处理工艺相比节约了30.0%~91.8%,表明亚硝化-厌氧氨氧化工艺处理奶牛场养殖废水具有良好的可行性及应用价值。Aiming at the technical problems of low nitrogen removal efficiency and high operating costs of traditional nitrogen removal treatment processes for the livestock wastewater from large-scale livestock and poultry farms,this paper proposes partial nitrification-Anammox denitrification process for the livestock wastewater,and a demonstration project study was conducted.The research results of the demonstration project indicate that partial nitrification-Anammox process can operate stably in the treatment of the livestock wastewater,the average mass concentrations of ammonia nitrogen(NH_(4)^(+)-N),chemical oxygen demand(COD),suspended solids(SS),and total nitrogen(TN)in the process effluent are 34,58,190,and 127 mg/L,respectively,and the average removal rates are 82.5%,81.7%,91.6%,and 58.3%,respectively,the effluent quality meets the requirements of the Discharge Standard of Pollutants for Livestock and Poultry Breeding(GB 18596—2001).The total cost of wastewater treatment in this process is 2.83 yuan/m^(3),which saves 30.0%-91.8%compared to other biological treatment processes.This indicates that partial nitrification-Anammox process for treating the livestock wastewater from dairy farms has good feasibility and application value.
