摘　　要：为解决挥发性有机污染地块传统调查手段存在的周期长、精度低、无效点位多等问题,采用膜界面探测(MIP)技术、实验室检测分析和EVS软件对挥发性有机物(VOCs)污染地块进行精细化调查。结果表明,MIP-PID信号值与实验室检测数据多项式拟合曲线相关系数(R)> 0.90;MIP技术与传统调查技术结合可减少采样点位,缩短调查周期;EVS可精准计算污染土壤方量和刻画污染空间分布。基于MIP辅助判断、靶向采样验证、EVS污染范围刻画的精准调查方法,可为VOCs污染地块精准调查及绿色低碳风险管控和修复提供一定参考。The traditional survey methods of Volatile Organic Contaminated sites have some problems,such as long period,low precision and many invalid points.In order to study the feasibility of MIP coupled EVS(Earth Volumetric Studio)in fine investigation of VOCs contaminated sites.Membrane Interface Probe(MIP)technology was used to quickly identify suspicious points,laboratory testing and analysis was used to scientifically verify the degree of pollution,and EvS was used to accurately delineate the pollution range.The results showed that the polynomial fiing curve correlation coefficient R>0.90 between MIP-PID signal value and laboratory detection data.The combination of MIP technology and traditional survey technology can reduce the drilling sampling points and shorten the survey period.The EVS can accurately calculate the volume of polluted soil and finely characterize the spatial distribution of pollution.The precise investigation method based on MIP assisted judgment,targeted sampling verification and EvS pollution range characterization constructed in this study can provide reference for the precise investigation of vOCs pollution plots,as well as green and low-carbon risk control and remediation.
