Device for detecting leachate leakage and leakage position in refuse landfill

Abstract

The invention discloses a device for detecting leachate leakage and a leakage position in a refuse landfill. The device comprises an electric wire network, a PVC (polyvinyl chloride) sleeve network and a high-density resistivity meter, wherein the electric wire network is composed of an X-direction electric wire array extending along the X direction and a Y-direction electric wire array extending along the Y direction; PVC sleeves are sleeved outside electric wires in the electric wire network to correspondingly form the PVC sleeve network, and the sleeve wall of each PVC sleeve is provided with holes through which leachate flows in and out; and the electric wire network and the PVC sleeve network are respectively arranged in a second-layer rubble layer in the refuse landfill or a lower-layer soil body of a leakage-proofing layer, and the X-direction electric wire array and the Y-direction electric wire array are respectively and electrically connected to the input end of the high-density resistivity meter which is positioned outside the refuse landfill. The device for detecting leachate leakage and the leakage position in the refuse landfill can be used for detecting the leachate leakage as well as detailed leakage position and range.

Description

technical field [0001] The invention relates to leachate detection equipment, in particular to a device for detection of leachate leakage and its position in landfill sites. Background technique [0002] With the rapid development of my country's economic construction and the improvement of people's living standards, more and more garbage needs to be landfilled. In modern sanitary landfills, geomembrane and clay layers are laid at the bottom for anti-seepage treatment. Affected by construction factors, such as geomembrane puncture, seam separation, and uneven settlement of the bottom clay layer, the geomembrane will be cracked, etc. It is difficult to ensure that there are no holes or cracks in the geomembrane. If the clay layer is not handled well, cracks will easily occur , so even with a landfill with double-layer anti-seepage treatment, it is difficult to guarantee that there will be no leachate leakage. [0003] Once the leachate leaks into the groundwater and soil, it...

Problems solved by technology

When leakage is detected by this method, serious leakage and groundwater soil pollution have often occurred, and the specific location of leachate leakage cannot be detected.
