基于蒙特卡罗法和层次分析法的污染场地地下水修复技术筛选方法研究

Screening method for groundwater remediation technology of contaminated sites based on MC and AHP

在工业转型发展过程中,出现了大量遗留污染场地,对地下水造成严重污染,并加重水资源短缺,而现阶段缺乏易操作的污染场地地下水修复技术筛选方法。为筛选有效的污染场地地下水修复技术,建立了基于层次分析法(AHP)与蒙特卡罗法(MC)的污染场地地下水修复技术筛选方法。该方法利用AHP构建指标体系,结合MC进行抽样,避免了定性描述和单一数值评价带来的不确定性。将该方法用于某铬渣污染场地地下水修复技术的筛选,发现化学氧化/还原是最适宜的修复技术,筛选结果符合实际。

With the industry process for modernization,more and more contaminated sites were revealed. Similarly, the groundwater in these contaminated sites was heavily polluted, which increased the shortage of water resource. However, an easy-to-operate screening method for groundwater remediation technology was lacking. Thus based on Monte Carlo （MC） and analytic hierarchy process （AHP） ,an effectiveness screening method for groundwater remediation technology of contanminated sites was established, by implying AHP for indicator system construction and MC for simulation sampling, which avoiding the uncertainty brought by qualitative description and single numerical evaluation. Also,a chrome polluted site was carried out to testify the performance of the screening method,showing chemical oxidation/reduction was the optimal remediation technology, which verified its reasonability.
