摘要
新污染物是近几年在水体中普遍存在的痕量有机污染物,具有高毒性、生物积累性等危害,对人类健康和生态系统造成了潜在威胁,如何高效去除水中的新污染物已成为研究人员日益关心的问题.纳滤作为一种高效率、低能耗、无污染的膜分离技术,在去除新污染物方面有很好的应用前景.结合国内外研究现状,文章详细分析了纳滤技术去除水中新污染物的机理及影响因素,重点讨论了纳滤膜改性与膜组合工艺对新污染物的去除效果研究,并对未来的相关研究和实际应用提出几点建议.
Abstract
Emerging pollutants are trace organic contaminant commonly found in water body in recent years,which exhibit characteristics of high toxicity,bio-accumulation and pose potential threats to human health and ecosystem.How to effectively remove emerging pollutants in water body has become an increasingly concerned problem for researchers.As a membrane separation technology with high efficiency,low energy consumption and non-pollution,nanofiltration has a promising application prospect in removing emerging pollutants.Based on the latest research progress at home and abroad,the paper analyzes the mechanism and influencing factors of emerging pollutants removal by nanofiltration technology in detail,emphatically discusses the review of the removal performance by nanofiltration membrane modification and combined processes,and puts forward some suggestions for future research and practical application.
