探究鸢尾对磷污染水体的去除效果
Explore the Removal Effect of Iris on Phosphorus Polluted Water

本文为探讨植物对富营养化水体中总磷的去除效果，选用挺水植物鸢尾为研究对象，进行模拟试验，从试验开始测定，每间隔7天采集水样一次，共采集7次，进行水样中总磷含量的测定。结果表明：经过采样间隔7天，水体中总磷含量下降8.2%~19%；经过采样间隔14天，水体中总磷含量下降26.8%~43.7%；经过采样间隔21天，水体中总磷含量下降35.0%~53.5%；经过采样间隔28天，水体中总磷含量下降40.2%~61.3%；经过采样间隔35天，水体中总磷含量下降39.2%~64.0%；经过采样间隔42天，水体中总磷含量下降41.2%~65.7%。试验表明，鸢尾对磷污染水体有一定的去除效果。
In this paper, in order to explore the effect of plants on the removal of total phosphorus in eutrophic water, the emergent plant iris was selected as the research object, and the simulation experiment was carried out. The results showed that after a sampling interval of 7 days, the total phosphorus content in the water body decreased by 8.2% to 19%; after a sampling interval of 14 days, the total phosphorus content in the water body decreased by 26.8% to 43.7%; after a sampling interval of 21 days, the total phosphorus content in the water body decreased by 35.0%~53.5%; after a sampling interval of 28 days, the total phosphorus content in the water body decreased by 40.2%~61.3%; after a sampling interval of 35 days, the total phosphorus content in the water body decreased by 39.2%~64.0%; after a sampling interval of 42 days, the total phosphorus content in the water body decreased by 41.2%~65.7%. Experiments show that iris has a certain effect on removing phosphorus polluted water bodies.
