基于地球物理方法的垃圾处理场污染物检测技术研究

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。

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

The traditional detection technology has problems such as non-obvious change of magnetic susceptibility and re-sistivity,resulting in poor detection effect. A geophysical method based pollutant detection technology in garbage disposal field is put 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 the landfill,the land-fill is divided into construction waste and garbage, and analysis of the geological structure of the geophysical profile, method of measuring 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.
