Abstract: Membrane filtration technology is a high and new technology developed in recent years, which has wide application foreground in papermaking wastewater treatment. The principles and the characteristics of membrane filtration technology, as well as the application in the treatment of papermaking wastewater, have been introduced in the paper. Besides, the application status and the research development of some kinds of important membrane technology, including the reverse osmosis, micro-filtration, ultra-filtration, pervaporation, liquid membrane and so on , have been summarized in the paper, among which the principle, the flow , the existing problems, the application and the exploitation of the reverse osmosis are the emphasis. In the addition, some developed new membrane technology such as the bipolar membrane are also referred in the paper. Finally, some key issues appeared in the applications of the membrane filtration technology are conclude and some possible solutions are mentioned.
