摘要
在实验数据基础上做出合理的外推,利用迁移公式,模拟了若干年后重金属离子在土壤中的迁移行为和相对浓度分布.分析了时间、水的通量密度、金属离子的吸附分配系数对金属离子在土壤中迁移及浓度分布的影响.结果表明,金属离子在土壤中的迁移主要受水的通量密度和吸附分配系数的影响,并随时间的增加而增加.
Based on the theory formula and experimental data, the migration and concentration distribution of heavy metal ions in the environment after a number of years were evaluated by using the parameters in suitable scope. Effects of time, water flux density, and distribution coefficients of metal ions on the migration and concentration distribution of heavy metal ions were also simulated in soil. The results indicate that the migration of heavy metal ions in soil is mainly dominated by the water flux density and distribution coefficients of the metal ions sorption to soil. The concentrations of the metal ions in soil increase with increasing time. The results are important for the evaluation of metal ions pollution to the environment.
