膜分离技术是一类新技术,借助选择透过性膜在外界能量作用或者化学位差下,分离与提纯混合物的方法。膜分离技术效率高,应用在生产和生活各个领域,特别在工业含盐废水的回收、利用方面应用价值大。人口数量急剧攀升,经济社会快速发展,水资源短缺严重,为此,人们日渐重视到污水废水的处理及有用物质的再利用。当前深入研究开发的膜分离法主要有以下几种:微滤(MF)、渗析(D)、反渗透(RO)等。本文研究了反渗透、电渗析、膜电解等一些膜分离技术在工业含盐废水处理中的应用,为相关研究提供参考和借鉴。
Membrane separation technology is a new type of technique that separates and purifies a mixture by the choice of a transmembrane membrane for energy or chemical shift. Membrane separation technology with high efficiency, used in all areas of production and life, especially in industrial salt water recycling, the use of large value. With the rapid population growth, rapid economic and social development and serious shortage of water resources, people increasingly attach importance to the treatment of sewage and wastewater and the reuse of useful substances. The current research and development of membrane separation are mainly the following: microfiltration (MF), dialysis (D), reverse osmosis (RO) and so on. This paper studies the reverse osmosis, electrodialysis, membrane electrolysis and some other membrane separation technology in the industrial treatment of salt-containing wastewater for the relevant research to provide reference and reference.
