Abstract:

As certain disadvantages existing in traditional water treatment techno logy, the advanced membrane separation has become more and more popular. An outl ine of the development history and general status of membrane separation technol ogy is given. It focuses on the application of reverse-osmosis, ultra-filtration membrane, microfiltration membrane, nanofiltration membrane and electrodialysis to seawater and salt water desalination, ultra-pure water preparation as well a s wastewater treatment. Involving many fields, membrane separation technology wi ll have a rapid growth and play much more important role in water treatment indu stry in 21 century.

Key words: water treatment, membrane, membrane separation

摘要:

由于传统的水处理技术都不同程度的存在着某些缺点,使得膜分离作为水处理技术中的先进技术得到了越来越广泛的应用。作者对膜分离技术的发展历史和基本情况作了概括性地介绍和总结;在此基础上着重分析了反渗透膜、超滤膜、微滤膜、纳滤膜、电渗析等各种膜分离技术在海水和苦咸水淡化、超纯水制备以及废水处理中的应用;由于涉及到众多领域,21世纪的膜分离技术将与众多学科交叉结合,发展更为迅速,在水处理领域发挥更加重要的作用。
