摘要
采用恒温培养方法研究了矿化垃圾对磷的吸附和解吸特性,同时与三种不同水稻土的磷吸附特性进行对比实验。结果表明,矿化垃圾对废水中磷的等温吸附曲线与Langmuir、Freundlich及Termkin等温吸附方程的拟合度均达到显著水平。与水稻土相比,矿化垃圾磷吸附容量大,吸附态磷的解吸速率与水稻土非常接近。
The characteristics of phosphate adsorption and desorption were investigated in different paddy soils and aged refuses under constant temperature. The results indicated that all phosphate adsorption curves could be described by Langmuir,Freundlich and Temkin equations. Compared with paddy soils, the maximum phosphate adsorption of aged refuse increased significantly and the desorption rate was approximate to paddy soils. The main factors affecting phophate absorption and desorption were pH?humus?active ferric oxide?active aluminous oxide?CaCO3 and CEC.
