摘  要:
以扬州市郊的少根紫萍、稀脉浮萍为试验材料,研究不同浮萍覆盖面积对营养液中总氮、总磷的去除效果。结果表明,不同投放密度与TN、TP的去除率有一定的线性关系,随着投放量的增加,浮萍对营养液中TN、TP的总去除率提高。单位投放密度的TN、TP去除率(去除率/投放密度)随着投放密度的增加而下降。

摘  要:
Selecting the local duckweed(Spirodela,Lemna aequinoctialis) to study the removal rate of TN and TP in the Hoagland nutrient solution by duckweed with different covering areas.The results showed that the removal rate of TN and TP had a certain linear relationship with the input density of duckweed,and the total removal rate of TN and TP increased when the input density of duckweed increased.But the removal rate of TN and TP per unit input density(removal rate/ input density) decreased along with the increase of the input density.
