在重金属迁移建模研究成果的基础上，考虑土壤对重金属的吸附特性，推导出土壤重金属复合污染物迁移转化整体模型。为求解该模型，分别引进 Langmuir 等温竞争吸附模型与土壤水分迁移模型。最后，以重金属 Zn 和 Cd 为例，数值模拟其在土壤中的垂向迁移过程，并利用 MATLAB 画出相关图形。
Study on the Heavy Metal Combined Pollution Model in Soil
Based on the previous achievements and considering the soil’s adsorption characteristics of heavy metal,this paper proposed an overall migration model of heavy metal compound contaminants in soil.In order to solve the problem,the Langmuir isotherm competitive adsorption model and water migration model in soil were applied.Finally,an numerical simula-tion example of Zn and Cd was shown as heavy metal’s vertical migration in soil and displayed by MATLAB.
