摘要
纳滤膜是介于反渗透膜和超滤膜之间的一种压力驱动膜,分离机理较反渗透膜和超滤膜复杂。由于具有分离选择性高、操作压力低、不需添加化学试剂、可回收有用物质等优点,纳滤膜在造纸废水、重金属废水、垃圾渗滤液、纺织废水等的处理及废水深度处理回用的研究、应用中受到高度重视,具有良好的应用前景。
Nanofiltration membrane is a kind of pressure-drived membrane between ultrafiltration membranes and reverse osmosis membranes. Its separating mechanism is more complex than ultrafiltration membranes and reverse osmosis membranes. Nanofiltration membrane has many advantages, such as higher selectivity, lower operating pres- sure,no chemical reagent,reclaimable, etc. Therefore, nano-filtration membrane attaches high importance to the treatment of paper-making wastewater, heavy metal wastewater, landfill-leachate, textile wastewater, etc. and to the study on advanced wastewater treatment and recycling. Its application prospect is very good.
