  • Patent number: 12000757
    Abstract: A method and system for leakage status evaluation and leaks location of a solid waste land disposal facility. The method includes: arranging an off-site emitting electrode for the solid waste land disposal facility, and arranging a plurality of intra-site receiving electrodes on a solid waste pile surface in a grid shape; selecting a power supply to collect a current value between the off-site emitting electrode and each of the intra-site receiving electrodes respectively, and determining a maximum current value point Mn of the solid waste pile surface and a maximum current value An; selecting an off-site point So2, and measuring a current value between the off-site emitting electrode and the point So2 as a reference current Ab under the same power supply condition; and determining a leakage status of the solid waste land disposal facility based on a ratio of the maximum current value An to the reference current Ab.
