膜分离技术是20世纪中后期发展起来的一项新兴分离技术,因其兼有分离、纯化、浓缩和精制的功能,又具有高效节能、操作方便、设备简单等传统分离技术所无可比拟的优越性,而成为当今分离科学中最重要的手段之一。文章对膜分离技术作了系统的阐述,并介绍了其在酶液浓缩中的应用现状,分析了制约我国膜分离技术在酶制剂工业化生产应用中的关键问题并对其应用前景进行了展望。

Membrane separation technology is an emerging separation technology developed in the late 20th century,besides the function of separation,purification,concentration and refinement,membrane separation has superiority in high efficiency,energy saving,easy operation and simple equipment in contrast with the traditional separation technologies.Nowadays membrane separation has become one of the most important means of modern separation science.In this paper,membrane separation technology is systematically reviewed and the present situation of its application in enzyme solution concentration is also introduced.The key problems limiting the application of membrane separation technology in industrial production of enzyme preparation are discussed,as well as its application in future.
