膜分离技术在造纸工业废水回用中的应用

造纸工业是我国水资源消耗大户，造纸废水水量大、有机物含量高、造成的环境污染影响大，对造纸废水治理在全世界范围内都在关注废水回用，提高水循环利用率，减少水资源消耗和废水排放污染。膜分离技术是在一定压力下进行混合液分离的技术，近年来膜分离技术快速发展，在海水淡化、化工、食晶、医药、电子等工业废水处理中应用较多，本文对膜分离技术在国内外造纸工业废水回用中的应用研究进行了介绍，并对膜分离技术在造纸工业废水回用的研究方向进行了论述。

Application of Membrane Separation Technology in Papermaking industry Wastewater reuse

Papermaking industry discharges large amount of high concentration organic wastewater, which causes serious environment pollution. Many countries pay close attention to papermaking industry wastewater treatment and reuse, in order to enhance the efficiency of water and reduce water resources consumption and water contamination. Membrane separation technology can separate mixture under certain pressure. This technology grows up rapidly and has widely been applied in sea water desalination, treatment of waste water from chemical, food, medicine, electronic industries. Application and study status of the membrane separation technology in treatment and reuse of papermaking industry wastewater were introduced, development trend of the membrane separation technology in the future was also discussed.
