一种填埋气含湿量的现场测定方法
By installing gas collection pipes and passive venting pipes in the cover layer, combined with thermometers and hygrometers, the moisture content of the landfill gas was measured, solving the problem of the unconsidered influence of water vapor and enabling accurate evaluation of the cover layer performance.

AI Technical Summary
Existing technologies fail to effectively account for the influence of water vapor in landfill gas, resulting in inaccurate evaluation of the landfill gas's anti-seepage and emission reduction performance, and a lack of effective measurement methods.
A digital thermometer and hygrometer are connected to a horizontal gas collection pipe and a vertical passive exhaust pipe to measure the temperature and humidity data at the bottom of the cover layer, calculate the moisture content of the landfill gas, calculate the absolute pressure of water vapor using the ideal gas law and Dalton's law of partial pressures, and calculate the moisture content of the landfill gas by combining the humidity and temperature data.
This paper provides a simple and feasible method to accurately determine the water vapor content in landfill gas, which helps to evaluate the seepage prevention performance of cover layers and the emission reduction performance of landfill gas.
