Modelling of the biodegradation of organic matter in municipal landfills

摘要

A model is presented to simulate the biodegradation of easily and slowly hydrolyzable organic matter, as well as the generation of biogas and heat release. The model is based on fundamental relationships among physical/ chemical, thermodynamical and microibal processes occurring inmunicipal landfills. Lola microbially-medi- ated degradation processes occurring in municipal land- fills, are simulated in terms of the hydrolysis of solid organic matter, the formation of glucose and acetate as intermediary carbon substrates and the generation of the biogases CH_4 and CO_2.
