Abstract: In this paper, the mechanism of nitrogen removal in the constructed wetland, together with the effects anic
carbon availability, dissolved oxygen, temperature, pH on the nitrogen removal was surmarized. In addition, the research
prospects of the constructed wetland to treat wastewater with high nitrogen and low carbon contents were also proposed.
Keywords: constructed wetland; high nitrogen and low carbon; nitrogen removal; research advances
随着我国经济、社会的快速发展以及城市化进程的加快,大量污水未经适当处理直接排入水体,导致河
流、湖泊等水体富营养化严重,生态系统退化,生态服务功能下降,甚至完全丧失,并呈进一步恶化趋势。
氮作为表征地表水水质状况的主要污染物指标之一,是影响水生态系统健康和稳定的重要因素。处理系统对
污染水体中氮的净化去除效率是评价处理系统效率的一个重要指标。
近几十年来,人工湿地作为一项具有效率高、投资低、运行维持费用低等优点[1]的污水生物处理技术而被
广泛用于处理各种污水,如生活污水[2]、工业废水[3]、暴雨径流[4]、
