摘要
着重介绍了电荷模型、细孔模型以及静电排斥和立体位阻模型等纳滤分离模型,对它们的应用范围及局限性作出一些评价。在此基础上,介绍纳滤膜在高含盐溶液脱盐处理中的应用,并讨论了纳滤高含盐溶液脱盐过程中的影响因素。
Such as the charge model the pore model as well as the electrostatic and steric hindrance model which can be applied to nanofiltration membranes were chiefly introduced. Some estimate about application ranges and limitations of the models were put forward. Moreover, the application of nanofiltration membrane disposing desalination of the solution containing high-sah concentration was introduced and the influenee factor on the desalination process of the nanofiltration was discussed on the basis.
