The most commonly used approach is to landfill and landfill costs low, currently contains 95% percent of total treatment of waste in China. Landfills of solid waste often contains large amounts of toxic substances and heavy metals ions, produced chemical reactions and generate large amount of harmful material, these harmful material exists in the leach ate of garbage, once into the groundwater, the quality of water will be destroyed, in order to prevent the leakage which cause pollution to environment, bring harm to the health of residents, leakage detection became an urgent and extremely meaningful work. At present, there has variety of leakage detection methods, but the existing leakage detection devices of solid waste landfill often have many difficult problems, such as high-cost, difficult to detect leakage. On the basis of nowadays detection principle, in view of the problems in them, just like high-cost, difficult to detect leakage, hard to protect, this paper develop a low-cost, automated device for landfill leakage detection. This device is suitable for solid waste landfill leakage detection during the operation, it has the function of real-time monitoring, and can locating leakage locations timely and accurate. The principle of this paper is meshed resistivity, detection of meshed resistivity in this paper use the crossfeed way of electrode, cycle through the entire site, we can get the
