摘要
以存在石油烃污染的典型加油站场地为研究对象,开展基于膜界面探测(membrane interface probe,MIP)的场地原位调查技术研究与应用。通过分析MIP搭载的火焰离子化检测仪(flame ionization detector,FID)和光电离子探测器(photo ionization detectors,PID)的检测数据,对该地块内的污染物分布情况进行了拟合,构建地块污染程度分布模型,寻找潜在污染区域。对比分析由传统场地调查所获得的实验室检测数据,发现MIP捕捉的污染分布区域较为准确,表明MIP在加油站场地调查中能够起到良好的辅助决策作用,尤其是对挥发性有机物的潜在污染区域有很强的指示性。通过在石油烃污染场地中的实际应用验证了MIP技术的适用性,以期能够指导更为精准化的场地环境调查工作。
In this paper,the site of a gas station,contaminated by petroleum hydrocarbons is used as a research object to conduct a site in situ survey technique for membrane interface probe(MIP).The pollution degree distribution model of the plot as a means of finding potential pollution is obtained by fitting the test data obtained on the flame ionization detector(FID) and photo ionization detectors(PID) carried by MIP.Based on the laboratory data,MIP can find the pollution distribution area accurately,especially in volatile organic contaminated sites,and play a very good role in assisting decision-making in gas station site investigation as it can.This study aims to make the site environmental investigation more precise through practical applications of MIP in petroleum hydrocarbon contaminated sites.
