摘要:
以溪荪鸢尾（Iris sanguinea）、黄菖蒲（Iris pseudacorus）、东方蓼（Polygonum orientale）、灯心草（Juncus effusus）和芦苇（Phragmites australis）5种典型水生植物为试材，采用水培的方法，研究了5种植物对富营养水体中总氮（TN)的去除效果的影响。结果表明：湿地植物对TN的去除起到了良好效果，高浓度处理中溪荪鸢尾、黄菖蒲、东方蓼、灯心草和芦苇对TN的去除率分别为67.2%、41.0%、45.1%、49.7%和38.7%；低浓度处理中分别为69.4%、58.7%、67.5%、68.4%和68.4%；在第14天溪荪鸢尾与东方蓼组水体中TN浓度已由15 mg/L分别降到0.11 mg/L和1.10 mg/L。高浓度处理下，不同种类水生植物对TN的去除能力不同；同种植物对低浓度处理中的TN去除效果显著高于高浓度处理。
Abstract:
Taking Iris sanguinea, Iris pseudacorus,Polygonum orientale,Juncus effuses and Phragmites australis as test materials,by the method of water culture,the effect of removal of total nitrogen (TN) in the eutrophicated water by 5 plants were studied.The results showed that the removal rates of all treatments with wetland plants were significantly higher than the control without plants,the removal rates of TN by Iris sanguinea, Iris pseudacorus,Polygonum orientale,Juncus effuses and Phragmites australis were 67.2%,41.0%,45.1%,49.7% and 38.7% in the high concentration treatment,and 69.4%,58.7%,67.5%,68.4% and 68.4% in the low concentration treatment,respectively.The concentration of TN has been reduced from 15 mg/L to 0.11 mg/L and 1.10 mg/L,respectively,under the treatments with Iris sanguine and Polygonum orientale.The removal rates were significant differences in the high concentration water,and the same plant showed a higher removal efficiency in the low concentration treatment.
