反渗透膜有机污染的研究现状综述

Review of Research Status of Organic Fouling for Reverse Osmosis Membrane

该文归纳了反渗透系统进水中有机物的种类和特征,综述了膜表面性质、溶液化学、操作条件和有机污染物性质对典型有机污染物(腐植酸、蛋白质、多糖和脂肪酸)污染过程的影响及可能的污染机理,最后提出了反渗透膜有机污染的控制方法。

In this paper, the species and characteristics of organic compounds in influent of reverse osmosis system were summarized. Effects of membrane surface properties, solution chemistry, operating conditions and organic fouling properties on pollution process of typical organic foulants such as humic acid, protein, polysaccharide and fatty acid, and the possible fouling mechanisms were reviewed. Finally, the control methods of organic fouling of reverse osmosis membrane are proposed.
