| 摘 要： | 构建一种改进型微曝气强化生态浮床污水静态模拟实验平台,利用该平台研究了3种水生植物黄菖蒲、西伯利亚鸢尾和水竹对水中Cu~(2+)的去除能力及富集特征;同时探究了不同曝气量下,黄菖蒲微曝气生态浮床对水中Cu~(2+)的去除效果。结果表明:在实验条件下,3种水生植物对水中Cu~(2+)的去除能力依次为黄菖蒲>西伯利亚鸢尾>水竹;当曝气量为7.5 L/min时,黄菖蒲微曝气生态浮床对水中Cu~(2+)的去除效果最好;3种植物的不同部位对重金属Cu~(2+)的吸收富集能力均表现为根部最强。

| Abstract: | Through constructing an enhanced ecological floating bed,Cu2+ removal rate and enrichment efficiency in Pseudacorus,Siberia iris and Phyllostachys heteroclada were investigated.The results showed that when the optimum aeration rate of Pseudacorus floating bed was 7.5 L/min,the floating bed had the maximum removal capacity to Cu2 +,followed by Siberia iris and Phyllostachys heteroclada.Three plant roots had the strongest enrichment ability to Cu2+ than the other parts. |
