摘　　要：从运行的先好氧后厌氧去除氨氮和亚硝酸氮的两相厌氧氨氧化反应器中成功的筛选出3株革兰氏阴性菌株。进一步研究发现,3株微生物菌株为具有厌氧氨氧化特性的硝化细菌。培养2d后,ⅡB菌使氨氮的浓度从初始188mg/L降到了0mg/L,ⅢC菌使亚硝酸氮的浓度从初始167mg/L降到了0mg/L。From the first run aerobic and followed anaerobic of the two - phase Anaerobic Ammonia Oxidation reactor which remove of ammonia nitrogen and nitrite nitrogen, three bacterium strains of gram - negative were isolated. Further study found that three bacterium strains are nitrification bacteria with anaerobic ammonia oxidation character. Inoculated Ⅱ B in liquid medium, after two days cultivation, the concentration of ammonia nitrogen from the initial 188mg/L dropped to 0mg/L, inoculated ⅢC in liquid medium, after two days cultivation, the concentration of nitrite nitrogen from the initial 167mg/L dropped to 0mg/L
