The selection of appropriate remediation technologies for groundwater pollution of coking-contaminated sites is a huge challenge.To address this problem,the"China Coking Site Pollution Remediation Database"was constructed in this study and a screening process for groundwater pollution remediation technology for coking sites was proposed.The screening system was constructed from four dimensions:technical applicability,society and environment,remediation cost,and remediation duration.Besides,the analytic hierarchy process and entropy weight methods based on a genetic algorithm were adopted to calculate the indicator weight of the remediation technology screening system,and the Monte Carlo algorithm was applied to simulate site information to reduce the uncertainty of the obtained site information and make the evaluation results more scientific.Finally,the model was applied to the screening of groundwater pollution remediation technology of the coking site in China,and the results showed that the scores of pump and treat technology ranked the top two in four dimensions and the total score ranked the first(21.6680).Thus,pump and treat technology was recommended for the remediation which was consistent with the actual site application.In all,this study provided a methodological basis and theoretical reference for the selection of groundwater pollution remediation technologies for coking sites in China.
