| 摘 要： | 测定水葫芦对宁德市东湖塘水体中总氮（TN）、总磷（11P）的清除作用；结果表明：经过25d的净化，水体中总氮的含量由3．45mg，L降至0．64mg／L，总去除率达80．2％；而总磷的浓度由原来的1．12mg／L降为0．26mg／L，总去除率为76．8％，这说明水葫芦对污水具有较强的净化能力．

| Abstract: | The removal ability of nitrogen and phosphorous by water hyacinth was studied. The results show that the content of the total nitrogen in the water decreased from 3.45mg/L to 0.64mg/L, and the content of the total phosphorous in the water decreased from 1.12mg/L to 0.26mg/L. The removal rates of TN and TP were 80.2% and 76.8% respectively. The results indicated that the water hyacinth had a great purification effect on eutrophicated water. |
