摘要
如何科学地为焦化地下水污染场地选择合适的修复技术是一项巨大的挑战,为解决这一难题,构建了“我国焦化场地污染修复数据库”,提出了焦化场地地下水污染修复技术筛选流程,并从技术可应用性、社会和环境、修复费用及修复时长4个维度构建了修复技术筛选体系,基于遗传算法的层次分析法和熵权法计算修复技术筛选体系指标权重,并应用蒙特卡洛算法模拟了场地信息,减少了场地信息获取的不确定性,使评价结果更为科学.将该模型应用于我国某焦化场地地下水污染修复技术的筛选,结果表明,抽取-处理技术在四个维度的得分排名均在前两名且总分排名第一(21.6680),推荐采用抽取-处理技术进行修复,与实际场地应用情况一致.
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.
