摘    要:采用复合式膜生物反应器处理青藏铁路沿线某车站低温生活污水,一年的运行实践表明,低温(水温6—10℃)时,反应器处理COD效果较常温降低,但运转过程中未发生质的变化,经过长时间保持较稳定的低温运转,污水温度与微生物建立稳定的平衡关系后,反应器表现出较好的COD去除效果和较强的抗冲击负荷能力,处理效果达到设计要求,出水达标排放。

关 键 词:复合式膜生物反应器  低温  生活污水

Abstract:Low temperature sewage was treated by membrane bioreactor of complex type (CMBR) on Qinghai- Tibet railway line. The results show that low sewage temperature(6- 10℃) leads to the removal rate of COD declining. After long-playing low temperature running, CMBR obtains the average COD removal rate of above 80%. Inflow COD volume loading has little influence on CMBR effluent.
Keywords:membrane bioreactor  low temperature  sewage
