| 摘 要： | 采用溴百里酚蓝（BTB）选择性培养基对采集样品进行初筛分离。初筛菌株在30℃，DM培养基培养3天后的溶液测定其TN、NO3-N、NO2-N浓度变化。最终成功分离得到一株编号为8#菌株对NO3-N的降解率91．70％，亚硝态氮累积量仅为0．61mg·L-1。该菌株反硝化能力较强，在实际的废水处理中具有一定的应用价值。

| Abstract: | By using BTB medium to isolate aerobic denitrifier.Among which the better strains experienced secondary screening:measuring the concentration of the TN、NO3-N、NO2-N in the DM media after 3 days’ cultivation.In case of the denitrification process,the concentration of the NO3-N、NO2-N were measured.The 8# NO3-N removal rate reached 91.70% and nitrite accumulation was in a low concentration of 0.61mg·L-1.The 8# was a high-eficiency aerobic denitrifier and it is useful in practical application. |
