Embodiment Construction

[0044] Please refer to figure 1 . Emitting electrodes 1 are laid on the geomembrane 5 with a distance of 10 m between each emitting electrode, and a receiving electrode 2 is embedded in the soil 10 outside the landfill 11 . The above two electrodes 1 and 2 are ruthenium-plated titanium sheet electrodes φ30mm×1mm, and the wires (1.5mm 2 ) are welded at the center of the ruthenium-plated titanium sheet, and are respectively connected to the positive (negative) poles of the constant voltage power supply 3 with a DC output of 1000V.

[0045] The detection electrodes 8 are laid under the geomembrane, and the distance between the detection electrodes is 3m. The reference electrodes 9 are laid in the soil away from the landfill area, and each detection electrode is connected with the reference electrode. The more the number of detection electrodes, the higher the detection accuracy, but the higher the investment of the detection system, in order to solve this contradiction, the uti...

Abstract

The present invention is electric detecting method and device for leakage of antiseepage layer garbage landfill. There are at least one emitting electrode set on earthwork film inside the landfill, one receiving electrode embedded inside soil outside the landfill, DC power source connected to the two electrodes; at least one detecting electrode laid under the earthwork film, one reference electrode laid outside the landfill and one seepage detecting instrument, which consists of motor, main control box and datan acquiring box, connected to the detecting electrode and the reference electrode.

Description

technical field [0001] The invention relates to an electrical detection method for leakage of an anti-seepage layer in a landfill site. [0002] The invention also relates to a detection device for carrying out the method described above. Background technique [0003] In order to prevent the groundwater from being polluted, the anti-seepage lining system of the landfill is an essential facility for the construction of the landfill. Its function is to isolate the inside and outside of the landfill and control the leachate from entering the clay and groundwater. The general materials of this system mainly include clay and artificial synthetic materials. The most commonly used artificial synthetic material is high-density polyethylene (HDPE). In the investment of landfill construction, the investment in anti-seepage layer is huge. Due to the quality of HDPE itself or construction reasons, the anti-seepage layer of the landfill often leaks. Therefore, it is particularly importa...
