纳滤膜去除饮用水中微量有机物的研究进展

Advances on trace organics removal from drinking-water by nanofiltration

对近年来国内外采用纳滤膜脱除饮用水中微量有害有机物的应用研究做了初步的归纳与综述,将饮用水中的有害有机物按其在水体中的常见性和重要性划分为消毒复产物(DBPs)和前驱物(FP)、环境内分泌干扰物(EDCs)、持久性有机物(POPs)、医药与个人护理品(PCPPs)、生物可同化有机物(AOC)、微囊藻毒素(MC)等6类,并对这几类有机物的纳滤膜脱除效果与机理进行较为深入的分析与讨论,认为纳滤膜能脱除饮用水中大部分微量有害有机物,对于提高饮用水水质和安全饮水起到保证作用。

In this paper, the removal of almost all important trace organics in drinking-water by nanofiltration all over the world in recent years has been reviewed. According to their importance and spread in water body, the trace organics were divided into ： DBPs （ disinfection by-products, FP （ formation precursors ）, EDCs （ environmental endocrine disrupting chemicals ）, POPs （persistent organic pollutants ）, PCPPs （pharmaceuticals and personal care products）, AOC （Assimilable organic carbon）, MC （microcystin）, and so on. The discussions on rejection efficiency and mechanism of those trace organics by nanofihration have been fully carried out. Based on the aforementioned analysis, the nanofiltration can be used to remove most of the harmful trace organics, and hence to improve the quality of drinking-water and ensure safe drinking water.
