摘要
结合国内外研究实例,综合阐述了人工湿地对污水中氮、磷和有机物等污染物质的去除机理以及在此方面国内的研究现状,分析了提高人工湿地处理能力的方法和途径,说明了利用自然过程进行污染物降解的人工湿地可以成为许多地区的污水处理方式,并且对这一技术的研究方向进行了探讨。
The mechanism of nitrogen, phosphomns removal by wetland and the current study in China with combination of the characteristics of agricultural non-point source pollution and the examples in China and abroad are described in the paper. The way to improve the pollutant re- moval ability of constructed wetland is analyzed. Wetland system for wastewater treatment that degrades pollutant via natural process can be the disposal mode of agricultural non-point source pollution in many regions in China. The future research directions of this technique are also discussed.
