Abstract

Anaerobic digestion is a microorganism-mediated bioredox and bioenergy system composed of series of biochemical conversions. Although heat of anaerobic digestion is an important thermal parameter, it has rarely been measured and calculated. In addition, heat of biohydrolysis and heat of bioredox for anaerobic digestion have not yet been explored. This study establishes Buswell's equation as an energy model to quantify standard heat of anaerobic digestion, standard heat of biohydrolysis, and standard heat of bioredox. Examples for counting standard heat of anaerobic digestion are demonstrated by integrating theoretical mathematical framework and thermochemical equation of Buswell's equation. Based on the derived mathematical equations, standard heat of anaerobic digestion, standard heat of biohydrolysis, and standard heat of bioredox can be determined accordingly. The graphical correlation between standard heat of biohydrolysis and standard heat of bioredox shows very strong linear relationship.
