Water pumping experiment determination system for vertical anti-seepage curtain defect position of hazardous waste landfill

Abstract

The invention discloses a water pumping experiment determination system for a vertical anti-seepage curtain defect position of a hazardous waste landfill. The water pumping experiment determination system comprises a defect judgment module and a defect determination module. The defect judgment module comprises a detection position generation unit and a data processing unit. The data processing unit is connected with the defect determination module. The detection position generation unit is used for generating an experiment detection position. The data processing unit is used for carrying out data acquisition, data analysis and data judgment on the information of the experiment detection position. The defect determination module comprises a defect area generation unit and a defect positiondetection unit. The defect area generation unit is used for generating a defect area according to the result of the data processing unit, the defect position detection unit is used for detecting the specific position of a defect, and the detection position generation unit comprises a pumping well position generation unit and a positioning observation well generation unit.

Description

technical field [0001] The invention relates to the field of anti-seepage engineering of hazardous waste landfills, in particular to a pumping test determination system for the position of defects in vertical anti-seepage curtains of hazardous waste landfills. Background technique [0002] A safe landfill is a disposal facility that places or stores hazardous waste in the soil. Its purpose is to bury or change the characteristics of hazardous waste. It is suitable for landfill disposal that cannot recycle its useful components or recycle its energy. Hazardous waste and landfill can be divided into three basic types: isolated landfill, controlled landfill and stable landfill. Hazardous waste landfill belongs to isolated landfill. The overall goal of a safe landfill is to isolate hazardous waste from the environment as much as possible. Landfills often use vertical anti-seepage curtains, usually on top of vertical anti-seepage curtains. The vertical anti-seepage curtain is to...

AI Technical Summary

Problems solved by technology

However, with the long-term use of the vertical anti-seepage curtain, the vertical anti-seepage curtain may have defects. If the defect position of the vertical anti-seepage curtain is not repaired in time, it may cause landfill gas and waste leachate to flow out of the landfill In addition, it will have adverse effects on the surrounding groundwater environment, the health of nearby residents, daily life and production activities.

However, the existing technology cannot quickly and effectively determine the defect location of the vertical anti-seepage curtain
