| 摘 要： | 为了研究联合修复技术在有机物污染场地中的筛选方法以及修复效果,以山西某搬迁遗留场地土壤修复工程为案例,本文提出了采用层次分析法（AHP）对常用的物理、化学、生物修复技术方法进行优选,最终确定“常温解吸+异位热脱附+填埋场覆土利用+水泥窑协同处置”的新联合修复模式,并且研究了该联合修复模式的处理效果及其对环境造成的影响。结果表明,AHP可用于有机污染场地修复最佳方案的筛选;采用该联合修复模式费用低、效果良好且未对周围环境造成影响。可见该联合修复模式能够有效地处理此类型场地污染土体。该修复模式的成功实施为类似污染场地土壤修复项目提供了借鉴和参考价值,并在一定程度上控制了土壤资源的流失。

| Abstract: | To investigate the screening approaches and remediation effects of combined remediation technology in organic contaminated sites, a relocation legacy site soil remediation project in Shanxi was used as a case study. In this paper, the commonly used physical, chemical and biological remediation technologies were screened by Analytic Hierarchy Process (AHP). The new combined remediation model of "Room temperature desorption + Ectopic thermal desorption + Landfill cover soil utilization + Cement kiln co-processing" was finally determined. The repair effect of the combined remediation model and its impact on the environment were studied. The results showed that AHP can be used for screening the best remediation solution for organic contaminated sites, and the combined remediation model has low cost, good effect and no impact on the surrounding. The combined remediation model was found to be effective in treating contaminated soils at this type of site. The successful implementation of this remediation model provides a guideline for similar remediation projects and controls the loss of soil resources to a certain extent. |
