摘要
介绍了人工湿地的特点、应用现状及其氮的去除机理,从植物、基质和供氧方式3个角度阐述了人工湿地在提高脱氮效果方面所做的研究,并指出人工湿地仍有着广阔的发展前景。
Constructed wetlands,the low cost efficient technology, which is suitable for China＇s sewage treatment, have widely used in waste water treatment. This paper describes the characters of constructed wetlands, their applications and the mechanism of nitrogen removal. From the aspects of the plants, the substrate and the way of providing the oxygen, the research on how to improve nitrogen removal by constructed wetlands is illustrated. And conclusion is made that there is still a vast development prospect on constructed wetlands.
