Study on MSW filtration experimentation and landfill hydrologic analysis

A large-scale test device was developed to study the behavior of the MSW filtration under different stress levels.By means of the simulation on the experimental result,the variation of hydraulic conductivity with the void ratio was depicted.Since the leachate yield was another key parameter in the process of landfill design,the U.S.EPA HELP(Hydrologic Evaluation of Landfill Performance) Model was utilized to simulate the hydrologic process of the landfill.It was indicated that the effect of the stress field on the hydraulic conductivity of MSW and the leachate yield in landfills was unneglectable.
