| 摘 要： | 膜生物反应器以其用膜取代常规活性污泥法中二沉池的突出优点迅速成为污水处理的新发展方向.研究了污泥膨胀时,膜生物反应器脱氮除磷的效果.分别对比了在正常情况下和污泥膨胀时,膜生物反应器对CODCr氨氮、TN、TP的去除率.试验结果表明:发生污泥膨胀后,对CODCr的去除率提高到96.51%,而对氨氮、TN、TP的去除率分别为75.9%、39.8%、19.7%,均有不同程度的下降.

| Abstract: | The membrane bioreactor has taken its obvious advantages by using its membrane for replacing the second sedimentation tank in conventional activated sludge process and become the new developing direction in wastewater treatment. The effect of membrane bioreaction on denitrification and dephosporization when the sludge swelling is studied. Under normal conditions and when sludge swelling, the removal rates of CODCr, ammonia-nitrogen, TB and TP affected by the membrane bioreactor are compared separately. The ... |
