| 摘 要： | 针对我国的农业面源污染的现状,探讨了不同湿地植物和不同水流方式的人工湿地对农业面源污染中氮素的去除效果。文章从氮素的去除机理出发,通过植物和水流方式两个方面对氮素的去除效果进行分析,得出结论如下:不同湿地植物对氮素净化效果有差异,但总体来说湿地植物的生物量越大、根系越发达净化效果越好;湿地系统脱氮过程中,大部分氮是由微生物作用去除的,而复合式湿地及根系发达的湿地植物对微生物作用有良好的促进作用。

| Abstract: | Combined with the status of agricultural non-point source pollution in China,the nitrogen removal efficiency for agricultural non-point pollution by artificial wetland with different wetland plants and flow modes has been analyzed.This paper,based on the discussion of nitrogen removal mechanism,explained nitrogen removal efficiency by plants and water flow modes and got conclusions as follows:Different wetland plants have different nitrogen purification effect,but generally the biomass is bigger and root mo... |
