Numerical Model of Leachate Recirculation in Bioreactor Landfills with High Kitchen Waste Content

Surface spraying, horizontal trenches, and vertical wells are the most common leachate recirculation system used at landfills in engineering practice. In order to quantify efficiency of three aforementioned systems, a hydro–biochem–mechanical-coupled model was developed present work, which can describe hydrodynamic biochemical behaviors food-waste-rich landfills. A typical landfill cell modeled COMSOL. The results indicate that accelerate decomposition municipal solid waste (MSW) with food-rich content, relieving acidification, improving gas generation efficiency, consequently, increasing early settlement
