The three-dimensional real-time three-dimensional leakage monitoring system is a leakage monitoring system composed of a collection station, a transmitting power supply, an electrode system and an operation terminal. It can realize real-time monitoring of landfill leakage, and continuously monitor the diffusion of pollutants underground after leakage occurs. As the country pays more attention to environmental protection, people are paying more and more attention to the environmental hazards caused by the leakage of waste landfills. The three-dimensional real-time three-dimensional leakage monitoring system has high sensitivity, simple operation and low cost. It is widely used in the leakage monitoring of waste landfills. It can effectively find leakage in a timely manner, thereby reducing the occurrence of pollution accidents.
