摘　　要：本文以实际猪场沼气废水为研究对象,以ASBR为反应器,接种厌氧消化污泥培养厌氧氨氧化细菌,厌氧氨氧化阶段成功启动后,研究了厌氧氨氧化脱氮最佳运行工艺。试验研究表明,厌氧氨氧化反应适宜的温度在35(±1)℃之间,适宜的pH在7.5～8.0之间,HRT选用24 h。当达到最佳运行参数时,NH4+-N的去除率达到87.6%,NO2--N的去除率达到99.96%。In this paper, the slurry from biogas digester on pig farm was studied using ASBR reactor, in which the anaerobic sludge was inoculated with nammox. Based on successful starting up of Anammox, the optimal operation parameters of anaerobic ammonia oxidation denitrification were studied. The experimental result showed that the optimal conditions were at temperature of 35℃, pH 7.5 - 8.0 and HRT of 24hours, at which the removal rates of NH4 ＋ -N and NO2 - -N reached 87.6 and 99.96% , respectively.
