| 摘 要： | 为了比较人工湿地废水处理中的湿地植物的去污能力,从中筛选出适宜人工湿地的湿地植物,并从邛海人工湿地采集5种植物,在相同浓度的生活废水中进行水培观察,对总氮(TN)、总磷(TP)、氨氮(NH3-N)、化学需氧量(COD)的去除效果进行了比较,并从去污力、根系、管理难易、景观美化作用等方面指标进行综合评定。比较结果表明,大薸和菱角对总氮和总磷有较高的去除率,菖蒲对NH3-N、TN、TP的去除率表现最差,鸢尾、风车草、菖蒲对COD有明显的去除作用。

| Abstract: | To screen suitable plants for artificial wetlands of Qionghai Lake, we collected five varieties of emergent
plants there and compared their decontaminating effects on polluted water. The contamination elements to be
removed included total nitrogen (TN), total phosphorus (TP), ammonia nitrogen (NH3-N) and chemical oxygen
demand (COD). Comprehensive evaluation was carried out from the aspects of decontaminating capacity, root system,
management and landscape beautification. The results showed that the TN and TP removal rates were higher in test
groups of Pistiastratiopica and Trapaincise, the Acoruscalamus showed the lowest rate for NH3-N, TN and TP
removals, and three varieties, i.e., Iris tectorum Maxim, Cyperusalternifolius and Acoruscalamus have obvious
effect on COD removal. |
