水生植物组合对社区公园景观水体净化修复研究

Experiment on Water Purification by Different Combinations of Aquatic Plants

    摘要
  • 摘要: 为探究不同水生植物组合对社区公园景观水体的修复效益，以挺水植物美人蕉 Canna indica，菖蒲 Acorus calamus，梭鱼草 Pontederia cordata，千屈菜 Lythrum salicaria，野生风车草 Cyperus alternifolius，花叶芦竹 Arundo donax var. versicolor；浮叶植物荇菜 Nymphoides peltatum，野天胡荽 Hydrocotyle vulgaris，大薸 Pistia stratiotes 9种水生植物为材料，对其按特征构建出 9种植物组合，于 2019年 8－9月在浙江农林大学东湖校区进行水培实验，分析其净化能力。结果表明，水生植物组合实验早期净化效果快，且在第二、第三周基本达到较大的净化率，随后逐步提高或趋于稳定；菖蒲 +野生风车草+大薸、荇菜 +梭鱼草+花叶芦竹这 2组水生植物组合具有较高的景观观赏性和净化能力，在处理 36 d时，其对化学需氧量（COD）的去除率均达 84%以上，对氨氮（NH4+-N）的去除率达 80%以上、对总磷（TP）的去除率达 83%以上，其中，花叶芦竹+荇菜组合的净化能力较低。本实验结果可为社区公园水生植物应用提供科学依据。

     

    Abstract: From August to September 2019, experiments were conducted in Lin’an, Zhejiang province on 12 combinations of aquatic plants such as Canna indica, Acorus calamus, Pontederia cordata, Lythrum salicaria, Cyperus alternifolius, Arundo donax var. versicolor, Nymphoides peltatum, Hydrocotyle vulgaris, Pistia stratiotes for determination of their purification ability of water. The results showed that it had fast purification effect at early stage, and topped the highest at the second and the third week, and then stabilized. The combination of A. calamus + C. alternifolius + P. stratiotes and P. cordata + N. peltatum+ A. donax var. versicolor had higher purification ability by the end of the 36th date of treatment, with 84% of removal rate of chemical oxygen demand (COD), over 80% of removal rate of ammonia nitrogen (NH4+-N), 83% of removal rate of the total phosphorus (TP). While the combination of A. donax var. versicolor + N. peltatum had lower purification ability.
