中文摘要:
      采用高密度电阻率成像法(ERT)对上海市某有机污染场地土壤污染原地修复进行研究,通过持续监测药剂注入前后电阻率的改变来推断药剂和污染物的扩散路径。结果表明,药剂扩散的影响半径介于2 m~4 m之间;其影响深度根据注药点和土壤渗透性差异而有所不同,在16 m处注药的影响深度大于监测深度20 m,ERT技术在监控原位注入修复过程中具有较好的可行性和适用性。
英文摘要:
      Electrical resistivity tomography (ERT) was used in in situ soil remediation at an organic contaminated site in Shanghai. The diffusion path of the agent and pollutants were inferred by continuous monitoring the changes of electrical resistivity before and after dosing. The results showed that the diffusion radius of the agent was between 2 m and 4 m. The influence of the agent varied with the difference of injection position and soil permeability. The influence of the agent injected in 16 m deep was greater than that in 20 m monitoring depth. ERT technology had good feasibility and applicability in monitoring in situ soil remediation.
