人工湿地对微污染物去除效果的研究进展

Research Progress on Removal Efficiency of Micropollutants by Constructed Wetlands

微污染物是近年来才逐渐兴起的一个词汇,微污染物是一种新型环境污染物,世界各国也开始重视这一大类环境污染物,如何有效控制污水中各种微污染物成为了水处理中所面临的难题之一。人工湿地作为近年来逐渐发展起来的一种生态污水处理技术,在微污染物的去除研究中逐渐受到关注。本文介绍了环境中不同种类的微污染物的来源、危害以及现有的去除方法,分析了人工湿地对各类微污染物的去除效果,分析了影响人工湿地去除微污染物的主要因素以及国内外对人工湿地去除微污染物的相关研究。最后,对人工湿地去除微污染物的生态处理技术进行总结和进一步研究的展望。

Micropollutant is a new kind of environmental pollutant, which is gradually rising in recent years. Countries all over the world have begun to pay attention to this kind of environmental pollutant. How to effectively control various micropollutants in sewage has become one of the difficult prob-lems in water treatment. As an ecological wastewater treatment technology gradually developed in recent years, constructed wetland has attracted more and more attention in the removal of micropollutants. This paper introduces the sources, hazards and existing removal methods of dif-ferent kinds of micropollutants in the environment, analyzes the removal effect of various micropollutants by constructed wetland, analyzes the main factors affecting the removal of micropollutants by constructed wetland, and analyzes the domestic and foreign research on the re-moval of micropollutants by constructed wetland. Finally, the ecological treatment technology of constructed wetland to remove micropollutants is summarized and the prospect of further research is put forward.
