摘要：
在膜生物反应器(MBR)中驯化活性污泥对溴氨酸进行生物降解实验。结果表明,由于溴氨酸的选择压,驯化过程中活性污泥浓度下降;TTC-脱氢酶活性下降并保持在较低的水平。在驯化期结束后,活性污泥对溴氨酸的脱色率和COD去除率可以分别达到90%和>50%。核糖体基因间隔序列分析(RISA)显示活性污泥群落呈现动态变化,生物多样性下降。

Abstract:
The activated sludge is domesticated in the membrane bioreactor (MBR) to degrade bromamine acid biologically. The results show that during the acclimation phase, due to the selective pressure of bromamine acid, the concentration of activated sludge decreases, the TTC-dehydrogenase activity declines and keeps at a low level. After the domestication, the decoloration rate of bromamine acid and COD removal rate reach 90% and >50%,respectively. The ribosomal intergenic sequence analysis ( RISA) show that there are dynamic changes in the microbial community and the genetic diversity of the activated sludge communities is declined.
