摘要
城市垃圾填埋是目前生活垃圾处置的主要方法,垃圾填埋场产生的积液、集气等二次污染物严重影响周边环境,因此必须对填埋场积液、集气情况进行检测及及处理。以河北某生活垃圾填埋场为例,根据填埋场地的物性参数建立二维模型,采用温纳斯伦贝斯混合测深装置模拟不同深度低阻体的响应特征:水平板状呈低阻圈闭形态,而直立板状则表现为水平方向延伸的低阻形态。通过高密度电法及时移电阻率法测试,结合钻孔验证,证实电阻率剖面图上的低电阻率与填埋场渗滤液赋存正相关,且填埋场中所测的渗滤液电阻率、残值及反射系数随时间具有动态变化特征。
The urban refuse dumping is the main method to dispose domestic garbage at present.The refuse dump produced secondary pollutants including percolate and exhaust gas can impact peripheral environment seriously,thus should be checked and disposed.Taking a domestic garbage dump in the Hebei Province as an example,according to physical property parameters of dump have established a 2D model.Using the Winas-Rumbez hybrid sounding device has simulated response features of low-resistivity body with different depths:horizontal plate presents low-resistivity trap form,while vertical plate presents horizontal extending low-resistivity form.Through high density electric and time-lapse resistivity tests,combined with drilling validation have confirmed the positive correlation between low-resistivity on resistivity section and refuse dump percolate hosting;besides,measured dump percolate resistivity,residual value and reflection coefficient have time dynamic variation features.
