膜蒸馏——一种新型膜分离技术
摘要:
膜蒸馏是最近几年发展起来的一种新型膜分离技术。它是利用高分子膜的某些结构上的功能来达到蒸馏目的的一种过程。膜蒸馏几乎是在常压下进行,也无需把溶液加热到沸点,只要膜两侧存在适当的温度差就可以进行,这就有可能利用太阳能等廉价的能源。本文叙述了膜分离的机理,着重介绍了水溶液膜蒸馏及其它一些应用情况。

MEMBRANE DISTLLATION-A NOVEL MEMBRANE SEPARATION TECHNOLOGY
Abstract:
When a microporous hydrophobic membrane separates two aqueous solutions at different temperature, a selective mass transfer across the membrane can be obtained. Membrane distillation may be used to solve some waste water problems, chemical separation and recovery, and concentration of aqeuous solution of substance which is sensitive to high temperature, with simple equipment. It is particularly attractive and promising. In this paper, the mechanism of the membrane distillation is described, and some information about membrane distillation of aqueous solution and other applications are introduced.
