| 摘 要： | 膜技术是２１世纪最有前途的水处理技术之一，ＵＦ膜和ＭＦ膜技术是其中很重要的一个组成部分。ＵＦ膜和ＭＦ膜可截留水中绝大部分悬浮物、胶体和细菌，是可靠的除浊和消毒工艺，但对水中有机物去除率不高，需要适当的预处理。膜污染是ＵＦ膜和ＭＦ膜技术用于净水处理的最大障碍，应尽可能减轻膜的浓差极化，延缓膜污染，从而延长膜的使用周期和使用寿命，取得更佳的经济效益。

| Abstract: | Technology of membrane is one of the primary important technologies of water treatment. UF and MF technology is a reliable technology for turbidity removing and disinfection, it can discharge the most suspensions,colloids and bacteria, but it is unefficient in removing organics from water, so some pretreatment is necessary. Membrane fouling is the main problem of this technology, so it is important to decrease concentration polarization to postpone membrane fouling, then we can lengthen the life of membrane, and so we can get a higher economical efficiency. |
