A system and method for detecting leakage in a landfill area

Abstract

The present disclosure provides a system and method for detecting leakage in a landfill area, and relates to the field of harmless landfill. One pole of the power supply, one end of all the second cables is respectively connected to the other pole of the power supply, the grid points are used to receive the leakage liquid and make the corresponding first cable and the second cable conduct to form a loop. The loops have different resistance values; the detection device is used to obtain the superimposed resistance value of the first cable and the second cable corresponding to the loop, so as to obtain the position of the grid point corresponding to the leakage, by setting the cable structure of the grid format , each grid point is connected to a different resistance value, corresponding to the landfill area above, when leakage occurs in the landfill area, the grid point is turned on, and the resistance value of the grid point is used to determine the position of the conductive grid point, thus Determine the location of the leak point corresponding to the landfill area, and locate the leak location.

Description

technical field [0001] The present disclosure relates to the field of harmless landfill, and in particular, to a system and method for detecting leakage in a landfill area. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] Landfill is the main means of harmless disposal of hazardous waste, and for the harmless landfill of hazardous waste, the requirements for rigid landfill construction under the condition of high groundwater level, soft soil area and other geological conditions are proposed, which need to be The leakage and harmful components in the rigid landfill are monitored, and the damage and leakage of the landfill unit can be observed under artificial visual conditions, and repairs can be made in time. [0004] In order to achieve the purpose of timely observation and repair of leakage, it is necessary to arrange long-term manual duty and insp...

AI Technical Summary

Problems solved by technology

However, the conductivity of the concrete medium of the rigid landfill structure is poor, and it is difficult to ensure the contact between the sensing electrode and the concrete, which greatly affects its applicability; the other is the online monitoring of leakage based on the principle of potential, and its basic principle is leakage The medium above and below the main anti-seepage barrier is connected, which leads to the difference in potential distribution

However, due to the rigid landfill structure, the space below the main anti-seepage barrier is relatively large (in order to allow people to enter, the lower space needs to be more than 60cm), and the amount of leachate leakage in the case of conventional leakage is difficult to make the leakage point above and below Media connectivity

Therefore, it is currently difficult to meet the online monitoring requirements for leakage in existing rigid landfills
