摘　　要：痕量有机物在水环境中普遍存在,具有长期残留性、生物积累性和强毒性等特点,对水生生态环境和人类健康产生了严重威胁。控制水环境中痕量有机物污染是当前环境领域的热点。纳滤膜技术在去除痕量有机物方面具有广泛的应用前景,但其去除效果受诸多因素的影响。结合国内外研究,文章总结了水质特性、操作条件以及膜表面性质对纳滤膜截留痕量有机物的影响,分析了以往研究中纳滤膜在不同影响因素的条件下得出的不同结论,并对未来纳滤膜技术的研究进行了展望。Trace organic compounds are ubiquitous in the aquatic environment, which have the characteristics of long-term residue, bioaccumulation and strong toxicity, and pose a serious threat to the aquatic ecological environment and human health. The control of trace organic pollutants in water environment has attracted increasing attention in the field of environment. Nanofiltration membrane technology has a wide application prospect in the removal of trace organic compounds, but its removal effect is affected by many factors. Combined with the research at home and abroad, the effects of water quality characteristics, operating conditions and membrane surface properties on the retention of trace organic compounds by nanofiltration membrane were first briefly summarized. Then the different conclusions of nanofiltration membrane under different influencing factors in previous studies were analyzed. Finally, the application prospects of the nanofiltration membrane technology were prospected as well.
