预处理技术在膜饮用水处理中的研究进展

Developments of pretreatment of membrane progress for potable water treatment

研究膜技术的预处理工艺,对微滤、超滤和纳滤等低压膜预处理技术在饮用水和微污染原水处理的最新研究进展进行了综述,并评述了混凝、活性炭、臭氧以及预氧化等工艺处理在防止化学损伤、延缓膜污染、强化膜分离效果等方面的研究和结论。

The pretreatments of membrane technology are introduced. New progresses on pretreatments of microfihration, uhrafihration and nonfihration, the low pressure membranes, for potable water and micropolluted raw water treatment are summarized. In addition, the research and conclusions about coagulation, the activated carbon adsorption, pre-ozone and pre-acidification in inhibiting chemical damage, mitigating the membrane fouling, enhancing the treatment efficient are analyzed.
