| 摘 要： | 以一体式膜生物反应器处理污水，对比研究污泥膨胀对一体式膜生物反应器的影响。结果表明：在污泥膨胀期，由于丝状菌的作用，一体式膜生物反应器中COD的去除率略有增加，但同时出现净水头压差增大、膜孔阻塞严重、膜外大量附着丝状菌等负面结果。由此认为，一体式膜生物反应器一旦发生污泥膨胀应采取必要的控制措施。

Study on Effect of Sludge Bulking in Submerged Membrane Bio-Reactor |
| |
| Abstract: | The sewage was treated by Submerged Membrane Bio reactor. The effect of sludge bulking to Submerged Membrane Bio reactor was investigated in this study through contrast research. When the sludge bulking appeared, the removal efficiency of COD in the submerged MBR increased slightly under the function of filamentous bacteria. However, the negative effects of the higher net water head differential pressures, the higher block rate of membrane pore and the great quantity of filamentous bacteria at the external surface presented at the same time. Thus, plenty of methods should be performed to control sludge bulking once it happened in MBR. |
