Abstract
In order to prevent scaling of the Leachate pipeline,this paper proposed that scale-forming ions could be removed in leachate by Landfdl gas before it's transported.The paper studied the control factors of the removal rate of scale-forming ions (calcium and magnesium ions) such as system temperature,pH of leachate and simulated landfill gas inlet rate (the proportion of Nitrogen and Carbon dioxide is 50% to 50%),and analyzed the chemical mechanism of these changes.The research indicates that the removal rate of scaling-forming ion goes up with a lower tempeture and a smaller amount of gas input combined with a higher pH of leachate.This research can provide a theoretaical foundation for the application of landfill gas removing scaleforming ion in engineering.关键词
