A Study on the Measurement of Gas Discharge from the Gas Vent of Sanitary Landfill(1)- analysis for minimizing the measurement error of flow meter -
초록
본 연구는 가스 포집관을 설치한 쓰레기 매립지에서의 가스 유동에 따른 모델 해석으로 부터 다음의 결과를 얻었다. 1) 저항이 없는 유량 계측기의 오차는, 투기계수
This study presents a relationship between gas quantity and measurement resistance using the bubble meter, the water head indicator and the rotor meter from the gas vent sanitary landfill. From the one-dimensional analyses and experiments, the below results have been obtained. The gas volume sourcing from the gas vent depends on the permeability of final cover soil, its cover depth and distance between the gas vents. The total gas volume producing in the interested domain may be accurately measured by the bubble meter, the water head indicator and the rotor meter if the clay is used for the final cover soil. The required times approaching to the steady-state are different with respect to the flow meters, one day is for the bubble meter and the water head indicator and one hour for the rotor meter.
