| 摘 要： | 本文研究的是采用一体式膜生物反应器处理生活污水过程中膜污染问题.试验结果表明:运行初期,由于膜孔堵塞膜通量下降速率较快,但随着运行时间的延长,膜通量下降缓慢且趋于一定值,膜污染也基本保持稳定;膜生物反应器处理高效优质,出水水质不受冲击负荷的影响,膜对部分有机物的截留作用使系统对COD的去除率保持在较高水平上,但膜对总磷的去除不明显;污泥沉降性能与膜污染具有相关性,污泥沉降性能的恶化直接加剧了膜污染.

| Abstract: | In this paper,a submerged membrane bioreactor was used to treat domestic wastewater,the result indicated that at the beginning the permeate flux declined rapidly,but with time the flux reduced slowly and membrane fouling reached a stable state during the experiment.MBR possesses the merits of high efficiency,immune to the shock loading but the removal rate of TP is low.In the same time,the sludge settleability was reduced and membrane fouling was increased becaused of this. |

| Keywords: | membrane bioreactor domestic wastewater removal rate sludge settleability |
