M. Elfadel et al., NUMERICAL MODELING OF GENERATION AND TRANSPORT OF GAS AND HEAT IN SANITARY LANDFILLS .2. MODEL APPLICATION, Waste management and research, 14(6), 1996, pp. 537-551
A mathematical model for the generation and transport of gas and heat
in a sanitary landfill was developed based on earlier work on the Moun
tain View Controlled Landfill Project (MVCLP) in California, U.S.A. Th
e present model incorporates biokinetic model equations describing the
dynamics of the microbial landfill ecosystem into multi-layer, time-d
ependent transport and generation of gas and heat models. It is based
on the fundamental principles governing the physical, chemical and mic
robiological processes in a porous media context such as a sanitary la
ndfill. The model includes biochemical and temperature feedback loops
to simulate the effects of their corresponding parameters on microbiol
ogical processes. The resulting integrated biokinetic, gas and heat ge
neration and transport model was used to simulate field data from the
MVCLP and to assess the sensitivity of model results to biological par
ameters. The model can be used to predict the rate and total productio
n of methane in a landfill. The present work is pressented in a series
of three papers: (I) model formulation; (II) model application; and (
III) sensitivity analysis. (C) 1996 ISWA
