摘　　要：为了了解三种常见植物对养殖废水中总磷（TP）的去除能力,通过模拟实验系统地研究了芦苇、凤眼莲、蕹菜对养殖废水中TP的去除效果.结果表明：三种供试植物对养殖废水中TP的去除效果大小为：芦苇-凤眼莲植物组合〉芦苇-蕹菜植物组合〉凤眼莲〉蕹菜〉芦苇.在处理15 d后,供试的三种植物对养殖废水中总磷的去除率在58%-91.25%之间,而对照组为37%-62.5%,供试植物对养殖废水中总磷有较强的去除效果.图5,表3,参9.In order to get a clear understarding of the ability of three common plants, namely, Phragmites australis, Eichhornia crassipes and Ipomoea aquatica Forsk to remove TP from livestock wastewater, a stimulated experiment has been done to make a systematic study on their removal of livestock breeding wastewater. These three experimental plants had great removal ability to TP in livestock breeding wastewater.The ability was arranged as follow： combination of Phragmites australis and Eichhornia cras- sipes〉 combination of Phragmites australis and Ipomoea aquatica Forsk 〉 Eichhornia crassipes 〉 lpomoea aquatiea Forsk 〉 Phragmites australis. After 15 days of this experiment process, the removal rate of TP ranged from 58% to 91.25% ,while the removal rate in control blank was between 37% and 62.5% ,which showed that these three experimental plants have great ability of removing TP in livestock breeding wastewater.5figs., 3tabs., 9refs.
