摘要: 为了提高人工湿地在寒冷季节的运行效率,对2种非夏季植物作为湿地植物处理生活污水的可行性进行了研究。结果表明,在本实验条件下2种植物对N、P元素都具有很好的去除效果,对COD的去除也达到45%~50%。通过单一植物系统和复合植物系统的处理效果比较,发现石龙芮酸模复合植物系统对污水中的P元素和COD的去除率更高。研究表明,石龙芮和酸模作为人工湿地植物具有可行性,与常规植物互补使用能在一定程度上延长人工湿地的运行时间。Abstract: In this paper, the feasibility of domestic sewage treatment by Poisonous buttercup and Dock in soilless culture was studied. Results shows that both the two plants can remove TN, TP efficiently, while the COD removal efficiency can reach to 45% and 50%. Compared with unitary plant system, Poisonous buttercup-Dock system showed high removal efficiencies of TP and COD. It is concluded that treatment of domestic sewage by Poisonous buttercup and Dock is effective and both plants can be used in cold area wetland.They can also extend the wetland’s work period.
