潜流人工湿地除氮机理的研究进展

Progress on the nitrogen removal mechanism in surface flow constructed wetland

介绍了湿地的概念及人工湿地的发展现状,阐述了人工湿地除氮的机理,提出了国内外提高污水中氮去除率的研究方法。提高人工湿地硝化能力,就可以提高湿地中氮去除率。调整湿地内部的结构,改善湿地内部的微环境,是提高人工湿地硝化能力的主要途径。

The concept and the present development of the constructed wetland were introdured. The mechanism of nitrogen removal in the constructed wetland was explained and the research methods of increasing nitrogen removal rate in our country and abroad were discussed, The nitrogen removal rate would be increased through enhancing the nitrification ability in constructed wetland. The main ways to enhance nitrification ability in constructed wetland were the adjustment of internal structure and improvement of inner microenvironment.
