| 摘 要： | 以长江三角洲地区常见的3种浮萍——稀脉浮萍(Lemna aequinoctialis)、少根紫萍(Spirodela oligorrhiza)和紫萍(Spriodela polyrrhiza)为对象,研究不同品种浮萍对HPO42-的吸收动力学影响。结果表明,3种浮萍对无机磷的吸收动力学特征基本可采用Michaelis-Menten方程描述3,种浮萍无机磷吸收速率V对磷浓度S双倒数曲线的拟合关系均在α=0.01水平上显著。稀脉浮萍对无机磷的亲和力较强,适宜应用于对低磷浓度污水的净化;紫萍对无机磷的最大吸收速率Vmax较高,适宜应用于对高磷浓度污水的净化。 |

| Abstract: | An increasing attention has been paid to the use of duckweed in treating eutrophicated water as a tool of bio-remediation of domestic wastewater.Phosphorus uptake kinetics was studied,of different species of duckweeds,i.e.Lemna aequinoctialis,Spirodela oligorrhiza and Spriodela polyrrhiza,which are common in the Yangtze River Delta area.Results show that the phosphorus uptake kinetics of the duckweeds could be expressed with the Michaelis-Menten equation;and the relation between phosphorus uptake rate(V) of... |
