Laboratory Simulation Study on Testing and Monitoring of Refuse Landfill Through Electrical Method
Leakage of garbage leachate from refuse landfill can cause pollution to surrounding soil, surface water and underground water, and thus can bring serious damage to our environment. Hence, it is very important to develop a real-time leakage survey system for refuse landfill. In traditional electrical survey method used for refuse landfill, the key point of potentiometric method lies in seepage spot detection while that of resistivity method lies in leachate migration monitoring. At present, there are very few garbage leakage survey systems which can combine these two methods together. By conducting laboratory simulation on the leakage monitoring mechanism of refuse landfill through electrical method, this thesis studied the differences between potentiometric method and resistivity method. Through analysis of actual measurement result data, feasibility of refuse landfill leakage survey system that can monitor seepage spots and leakage scale at the same time has been verified.
