基于层次分析法的重金属污染土固化效果评价
Assessment of Stabilization Effect on Heavy Metal-Contaminated Soil Through Analytic Hierarchy Process
摘要
Abstract
[Purposes]In view of the lack of a unified evaluation system for comprehensively as-sessing the solidification performance of the novel curing agent(red mud+carbide slag+phospho-gypsum)on soils contaminated with different heavy metals,in this study,an evaluation model is estab-lished and the weight of each evaluation index is clarified.[Methods]In this study,a"red mud+cal-cium-based+phosphorus-based"stabilizer was used to examine the performance of soils contaminat-ed with high concentrations of various heavy metals,and the Analytic Hierarchy Process(AHP)was employed to identify the primary factors influencing stabilization effectiveness.An evaluation model was developed to assess the stabilization performance of the contaminated soils,and the weights of the evaluation indices were determined.The study's conclusions were validated through microscopic anal-yses and speciation analyses of heavy metals,confirming the high reliability of the results.[Results]The study results indicate that the factors influencing the evaluation of heavy metal soil stabilizers ef-fectiveness are as follows:compressive strength=permeability coefficient>pH value>environmen-tal hazard>stabilization efficiency,with corresponding weight coefficients of 0.320,0.320,0.164,0.160,and 0.036,respectively.关键词
