高密度电法在垃圾填埋场渗滤液调查中的研究

Study on High Density Electrical Method in Landfill Leachate Investigation

随着城市发展,垃圾填埋场污水渗漏的问题开始暴露。高密度电阻率法由于具有高分辨率、高效、高自动化程度和异常特征明显等特性,在土层污染调查中逐渐发挥重要作用。通过Res2dmod软件模拟垃圾填埋场的电性分布特征,以及渗漏液对土层电阻率值影响的实验,再结合湖北省石首市某地非正规垃圾填埋场污水渗漏的调查实例,认为高密度电阻率法能准确识别垃圾填埋场的范围以及垃圾渗滤液严重污染区。为后期开展垃圾填埋场的污染治理和土壤修复提供物探依据。

With the development of the city,the problem of sewage leakage in landfills has begun to be exposed.The high-density resistivity method has gradually played an important role in soil pollution investigation due to its high resolution,high efficiency,high degree of automation and obvious abnormal characteristics.In this paper,through res2dmod software to simulate the electrical distribution characteristics of landfill site,and the influence of leakage liquid on soil resistivity value,combined with an investigation example of sewage leakage from an irregular landfill site in Shishou,it is considered that the high density resistivity method can accurately identify the scope of the landfill site and the seriously polluted area of waste leachate.It provides the geophysical basis for the later pollution control and soil remediation of the landfill site.
