【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.更多还原

【Abstract】 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 crassipes > combination of Phragmites australis and Ipomoea aquatica Forsk > Eichhornia crassipes > Ipomoea aquatica 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.更多还原
