Research on Pollution Detection Technology of Waste Disposal Field Based on Geophysical Method

传统检测技术存在磁化率和电阻率变化不明显等问题,导致检测效果差,提出基于地球物理方法的垃圾处理场污染物检测技术。构建非预先处理三维在线检测系统,实时采集电阻率,对电性出现的异常情况进行检测,获取物理土壤物性,根据垃圾处理场的地理结构,将垃圾场分为建筑垃圾和生活垃圾,并分析地质剖面结构图;采用地球物理法对测线进行布置,并对电性和土壤磁性变化展开分析,以此为基础对污染物进行检测。通过实验验证,该检测技术与传统技术相比磁化率和电阻率变化明显,检测效果良好。

The traditional detection technology has problems such as non - obvious change of magnetic susceptsistivity ,resulting in poor detection effect. A geophysical method based pollutant detection technology in garbage disposal field isput forward. The study constructs the non pre processing of 3D online detection system , real - time detection of abnormal resistivi-ty ,electrical appears , to obtain the physical properties of the soil , according to the geographical structure of tfill is divided into construction waste and garbage , and analysis of the geological structure of the geomeasuring line layout and , on the electrical and magnetic changes of soil analysis , as a basis for detection of pollutants. The test results show ^ that the magnetic susceptibility and resistivity change obviously compared with the traditional technology , and the de-tection results are good.
