河北省平原区填埋物污染的电性识别特征

Electrical Identification Characteristics of Landfill Pollution in Hebei Plain Area

针对河北省平原区工业固废和生活垃圾两类填埋场地,采用“高密度电阻率法+激电测深+时谱激电参数”的组合方法,确定了污染物/填埋物的电性识别特征,所圈定的污染物的空间分布与钻孔验证结果相吻合,结果表明:高密度电阻率法效率高、抗干扰能力强,更突出浅部信息,是快速识别目标区的重要参考;时谱激电参数特征在污染物的识别和圈定中较传统激电参数则更为稳定,该组合方法在工业固废填埋物、生活垃圾填埋场渗漏污染的探测中相互印证、相互补充,取得了较好的识别效果。

For the two types of landfill sites including the industrial solid waste and domestic waste in Hebei Plain area,the electric identification characteristics of pollutants/landfill were determined by the combination method of“High density resistivity method+Induced polarization(IP)sounding+time spectrum IP parameters”,and the spatial distribution of the contaminants delineated was consistent with the results of the borehole verification.The results show that the high density resistivity method has the advantages of high efficiency,strong anti-interference ability,and more prominent shallow information,which provides an important reference for rapid identification of the target area.The characteristics of time-spectrum IP parameters are more stable than the traditional P parameters in the identification and delineation of pollutants.The combined method is verified and supplemented in the detection of leakage pollution of industrial solid waste landfill and domestic waste landfill,and has achieved good identification effect.
