摘要：
The long-term operation of a methane biofilter depends on maintaining a favorable environment for methanotrophic bacteria within the porous medium supporting their growth. The concentrations of methane and oxygen, moisture content, and temperature were identified as the most important factors influencing the performance of methane biofilters (MBFs). This paper presents a comprehensive one-dimensional mathematical model capable of predicting the methane oxidation capacity of MBFs based on gas and moisture transport, and heat transfer. The finite difference method was used to spatially discretize the nonlinear partial differential equations and the equations were solved explicitly. The model was calibrated and verified using laboratory experimental data. © 2007 ASCE.
