摘要
分别从沉积物对磷的吸附动力学与等温吸附两个角度出发,通过模拟对滇池沉积物的吸附特性进行了研究.结果表明:(1)滇池沉积物吸磷和释磷都是在2 h内快速进行,12 h后基本达到了动态平衡;(2)E lovich方程对沉积物吸磷的拟合最优;(3)草海沉积物对磷的吸附容量与吸附速率都要大于外海.
From the point of phosphate adsorption kinetic and isothermal adsorption, this paper studies the adsorption characteristics of sediments of Dianchi Lake through simulation. The results show ： （ 1 ） Phosphorus adsorption of sediments of Dianchi lake run fastest in 2 h, and basically reach the state of dynamic balance after 12 h ; （2） The best fitting to phosphorus adsorption of sediments is the equation of Elovich ; （ 3 ） The absorptive capability and rates of Caohai sediments are better than those of Waihai.
