膜界面探测器是一项采用直接推进技术,可实时提供场地地下挥发性有机物近乎连续分布信息的直接感测工具。以某历史上从事有机氯农药生产的废弃工业场地为例,运用该技术,配置土壤电导率传感器、电子捕获检测器以及氢火焰离子化检测器,对该场地中潜在污染区域进行快速筛选调查,初步确定了土壤和地下水中挥发性有机物污染的热点区域及其三维分布和地层信息,为后续进一步调查方案优化、场地概念模型建立及后续修复方案设计等提供了重要的信息。
膜界麵探測器是一項採用直接推進技術,可實時提供場地地下揮髮性有機物近乎連續分佈信息的直接感測工具。以某歷史上從事有機氯農藥生產的廢棄工業場地為例,運用該技術,配置土壤電導率傳感器、電子捕穫檢測器以及氫火燄離子化檢測器,對該場地中潛在汙染區域進行快速篩選調查,初步確定瞭土壤和地下水中揮髮性有機物汙染的熱點區域及其三維分佈和地層信息,為後續進一步調查方案優化、場地概唸模型建立及後續脩複方案設計等提供瞭重要的信息。

The membrane interface probe (MIP)is a direct-push,real-time and direct-sensing tool that pro-vides near-continuous data on the distribution of volatile organic compounds (VOCs)in the subsurface.A geo-probe equipped with electrical conductivity (EC ),electronic capture detector (ECD),and flame ion detector (FID)was used for the MIP survey at the potential areas of environmental concern at a brownfield site,which was previously involved in the manufacturing of organochlorine pesticides.The MIP system was successfully in horizontal and vertical delineation of the soil and groundwater total VOCs at the study site,which provided valua-ble information on subsurface lithology and VOCs distribution for the conceptual site model development,and de-sign of the further site delineation and remediation.
