| 摘 要： | 对活性污泥—膜生物反应器、生物膜—膜生物反应器、复合式膜生物反应器的除污效果和膜污染趋势进行了研究。结果表明:活性污泥—膜生物反应器的膜污染程度最轻,膜通量下降速度最慢,膜污染也最容易消除;生物膜—膜生物反应器的膜污染程度最重,膜通量的下降速度最快;较大的曝气量可减轻膜的污染程度并减缓膜通量的下降速度。

| Abstract: | Pollutants removal efficiency and membrane fouling in activated sludge-membrane bioreactor (MBR), biofilm-MBR, and composite MBR were studied. The result shows that in activated sludge-MBR, the least membrane fouling is observed and is easy to be removed, and membrane flux is reduced at the lowest rate. The biofilm-MBR has the heaviest membrane fouling and membrane flux is reduced at the most rapid rate. More air intensive aeration can alleviate the membrane fouling and slow down the reduction rate of membrane flux. |
