摘要
以“污水土地处理条件下磷的迁移转化模拟试验”为基础 ,根据磷在土壤中的迁移转化机理 ,提出了定量模拟磷在土壤中迁移转化的联合模型。联合模型包括水运动模型和溶质运动模型两部分 ,综合考虑磷在土壤中迁移、转化和沉淀等过程。在传统的溶质运动模型基础上添加化学转化项形成了具有磷的反应特点的溶质运动模型。通过实测值与计算值的比较 。
Based on the soil experiment simulating phosphorus transferring and transforming in soils and the mechanism of phosphorus transferring and transforming in soils, a united model about phosphorus transferring and transforming in soils was put forward. The united model consists of water model and phosphorus solute model, so transfer, transformation and precipitation can be considered synthetically. Chemical transform items including phosphorus adsorption and precipitation action are considered in the solute model. According to the comparison of the measured value and calculated value, the rationality and applicability of the united model are validated.\;
