Abstract:

Industrial desalination technique has mainly been conducted by using polymeric separating membranes.However,organic membranes have disadvantages,such as short performance life,easy to be polluted,low biochemical stability,and hard to be regenerated,which seriously hinder the development of desalination techniques.Instead,the zeolite membranes whose chemical stability is high,and desalination separating performance excellent,can be used as an alternative to polymeric membranes for the desalination of seawater and complicated brine wastewater treatment. Researches relating to the application of the new type of zeolite membranes to seawater desalination and brine wastewater treatment are summarized. This kind of technique can make up for the insufficiency existing in organic membrane desalination technique.

Key words: zeolite membrane, seawater desalination, reverse osmosis, brine wastewater

摘要:

目前工业淡化技术主要采用有机高分子分离膜材料,但有机膜材料存在使用寿命短、易污染、生化稳定性低且再生困难等缺点,严重阻碍了淡化技术的发展。而化学稳定性好且脱盐分离性能优异的沸石膜可能成为海水淡化和复杂含盐废水处理中有机膜的替代材料。对利用新型沸石膜材料进行海水淡化和含盐废水处理的相关研究进行了综述,该类技术可以有效弥补有机膜脱盐技术中存在的不足。
