APPLICATION OF ELECTRICAL RESISTIVITY TOMOGRAPHY IN EFFECTIVENESS EVALUATION OF REAGENT INJECTION OF IN-SITU SITE REMEDIATION

摘要: 场地原位修复中的修复药剂灌注成效是场地修复成果的关键,因此如何评价修复药剂灌注成效对场地原位修复具有重要意义。采用电阻率成像法(electrical resistivity tomography, ERT)对云南某焦化场地在原位修复过程中的修复药剂灌注成效进行评价。根据灌注前、灌注中、灌注后的地下电性差异及变化特征,推断修复药剂在地下的传输分布情形。结果表明:灌注前后监测井中地下水的水温、pH、电导率、氧化还原电位、溶解氧等基本水质参数的变化与场地2D与3D剖面的电性变化基本保持一致,表明修复药剂灌注成效较好,证实了ERT在原位修复药剂灌注成效评价中具有较好的可行性和适用性,可对类似场地原位修复提供参考借鉴。Abstract: The effect of agent injection in-situ is the key to the results of site remediation. Therefore, evaluating the effect of agent injection is of great significance to site in-situ remediation. In this paper, the effect of agent injection in the process of in-situ repairing a coking site in Yunnan was evaluated by using the cross-hole earth resistance imaging method (ERT). The transmission and distribution of the repairing agent were estimated according to the underground electrical information and electrical changes before, during and after perfusion. The results showed that the changes in water temperature, pH, conductivity, redox potential, dissolved oxygen and other basic water quality parameters of the groundwater in the monitoring wells before and after the injection, were basically consistent with the electrical changes of the 2D and 3D profiles of the site, indicating that the injection effect of the repair agent was good, and it was confirmed that ERT had good feasibility and applicability in the evaluation of injection effect of the in-situ repairing agents, which can provide a reference for the in-situ repairing of similar sites.
