膜分离技术在家用净水机中的应用

本文介绍了膜分离技术,包括微滤、超滤、纳滤和反渗透技术的原理、应用范围、操作条件。重点介绍了膜分离技术在家用净水机中的应用现状,分析了几种分离技术在净水应用中的优缺点,并对膜分离技术处理饮用水的发展前景提出了建议。结果表明反渗透方法是目前最有效的和最成熟的家用净水技术,未来家用净水技术发展的重点是纳滤技术。

Membrane separation technology was introduced briefly in this paper,including the separation principle,scope of application and operating conditions of microfiltration,nanofiltration,ultrafiltration and reverse osmosis(RO)membrane technology.This paper focused on the application,merit and demerit of difference membrane technologies for the household water purification.The suggestion about the development of membrane technology in drinking water purification was made.The RO membrane technology is efficient and mature technology for household water purification,and nanofiltration technology is the key point in the future development of household water purification.
