基于PMF模型的煤矿区重金属污染土壤修复研究

Study on Remediation of Heavy Metal Contaminated Soil in Coal Mine Area Based on PMF Model

克里金差值修复方法的去除效率低,无法修复被煤矿区重金属污染的土壤。为此,提出基于PMF模型的煤矿区重金属污染土壤修复研究。先测定煤矿区重金属污染土壤性质,再根据测定结果,运用PMF模型中的AHP算法,评价重金属污染土壤程度。完成上述操作后,构建PMF煤矿区重金属污染土壤修复模型,实现重金属污染土壤修复。由此,完成基于PMF模型的煤矿区重金属污染土壤修复研究。最后,进入实验部分,使用基于PMF模型的煤矿区重金属污染土壤修复方法和克里金差值修复方法,去除被重金属污染土壤的锌离子浓度。

The removal efficiency of Kriging difference method is low,and it can't repair the soil polluted by heavy metals in coal mine area.Therefore,a PMF model was proposed to study the remediation of heavy metal contaminated soil in coal mine area.Firstly,the properties of heavy metal polluted soil in coal mine area were determined,and then according to the results,the degree of heavy metal polluted soil was evaluated by AHP algorithm in PMF model.After the above operations,the PMF coal mine area heavy metal contaminated soil remediation model is constructed to achieve heavy metal contaminated soil remediation.Therefore,the study on remediation of heavy metal contaminated soil in coal mine area based on PMF model was completed.Finally,in the experimental part,we use the PMF model-based remediation method of heavy metal contaminated soil and Kriging difference remediation method to remove the zinc concentration of heavy metal contaminated soil.
