| 摘 要： | 膜污染问题是影响膜生物反应器发展的一项关键技术。文章对膜污染中凝胶层的产生机理进行了研究与分析，认为凝胶层形成首先是由有机物在膜表面的吸附开始．在膜面浓差极化、生物污染及膜孔堵塞影响的共同作用下，使凝胶层迅速增厚，从而导致膜的严重污染；文章还对膜污染的控制进行了研究分析。 |
| 关 键 词： | 膜污染 凝胶层 膜生物反应器 |

| Abstract: | The problem of membrane fouling is a key technology in development of MBR. The paper studied mechanism of gel layer forming during membrane fouling, and considered that gel layer was formed first begin with organic material being adsorbed on the surface of membrane; then for the resistance of concentration polarization, microbe pollution and membrane pore blocking, gel layer became thicker quickly; and at last it led heavy fouling of membrane. In the end, the paper also studied methods of controlling the membrane fouling. |
| Keywords: | Membrane fouling Gel layer Membrane reactor (MBR) |
