中空纤维膜是一种具有特殊选择性分离功能的高分子材料,它能把流体物质分隔成不相同的两个部分,使其中的一种或几种物质能透过,而将其它物质分离出来。与常规分离方法相比,膜分离过程具有能耗低、单级分离效率高、过程简单、不污染环境等优点,已广泛应用于水处理、化工、电子、医药、食品加工等领域,成为本世纪分离科学中最重要的技术之一,是环境保护和环境治理的优选产业技术。
Hollow fiber membrane is a kind of special selective separation of the polymer material, which can separate the fluid material into two different parts, so that one or more of the material can be through, and other materials separated . Compared with the conventional separation method, the membrane separation process has the advantages of low energy consumption, high single-stage separation efficiency, simple process and no pollution to the environment, and has been widely used in the field of water treatment, chemical industry, electronics, medicine, food processing and the like One of the most important technologies in the science of century separation is the preferred industrial technology for environmental protection and environmental governance.
