An emitting electrode is placed in protection layer of geomemberance of landfill, and a receiving electrode is placed in the soil under the film of geomemeberance, two ends of signal source are connected between emitting electrode and receiving electrode. Multiple detecting electrode are placed in protection layer, each of which is connected with data collecting processor respectively, orientating by detecting the electric potential difference of each point. Signal is connected with data collecting processor and controlled by said data collecting processor. Each detecting electrode signal is added to active low pass filter after low pass filtering and transient suppression, output signal is entered analog-to-digital converter to transmit, data of each point is carried on leak judgement and the corresponding coordinate position is showed on display. The device of present invention has advantages of high speed detecting, high veracity and high omission factor.
