摘　　要：以生物滤池为反应器,以NH_4^+-N、NO_2-^-N的浓度变化为指标,对厌氧氨氧化菌种的活性恢复进行试验。结果表明:厌氧氨氧化菌种的活性恢复具有一定的稳定适应期,本试验条件下适应期为14d,24d即可完成活性恢复,NH_4^+-N、NO_2-^-N去除量比值为(1∶1.27)^(1∶1.32),接近厌氧氨氧化过程1∶1.31的理论值。Biological filter as the reactor and the concentration change of ammonia and nitrite as the index,the recovery of the activity of the anaerobic ammonium oxidizing bacteria was tested.The results showed that there was a stabilized period which was 14 days for the recovery of the bacteria activity.The activity recovery was completed after 24 days.The removal rate of ammonia and nitrite ratio was between 1∶1.27 to 1∶1.32,which was closed to the theoretical value in anaerobic ammonium oxidation process.
