某废弃矿山重金属污染土壤治理约束优化研究

Constrained Optimization of Heavy Metal Contaminated Soil Treatment in an Abandoned Mine

矿产开采过程中容易造成土壤重金属污染,治理土壤重金属污染有利于土壤的修复和二次利用。提出废弃矿山重金属污染土壤治理约束优化研究方法,首先介绍了研究土壤重金属污染所用的试剂和仪器,以及土壤采样和实验过程。其次,在SPPSS19.0软件中输入实验数据,分析土壤中重金属元素的空间分布特征,建立扰动指数函数,分析土壤重金属污染受人类活动的影响,通过地累积指数法获取重金属对矿区土壤产生的污染程度。最后,根据上述分析结果提出土壤治理约束优化策略。

Mineral mining easily leads to heavy metal pollution in soil.Controlling heavy metal pollution in soil is beneficial to soil remediation and secondary utilization.A constrained optimization research method for heavy metal contaminated soil treatment in abandoned mines is proposed.Firstly,the reagents and instruments were used to study heavy metal pollution in soil,as well as the soil sampling and experimental processes.Secondly,experimental data were imputed into SPPSS19.0 software to analyze the spatial distribution characteristics of heavy metal elements in soil.A disturbance index function is established to analyze the impact of human activities on heavy metal pollution in soil.The pollution level of heavy metal on mining area soil is obtained through the ground accumulation index method.Based on the above analysis results,a constrained optimization strategy for soil governance is proposed.
