Kinetic Models of Hydrogen Production Process by Batch Anaerobic Fermentation from Contained Sugar Wastewater

Abstract:

The processes of biomass growth, hydrogen production and sucrose degradation were systemically investigated about batch anaerobic fermentation which is based on activated sludge for a basic strain and the simulating sucrose wastewater for a substrate. The kinetics of microbial growth, hydrogen production and sucrose degradation were proposed according to the Compertz equation and the Luedeking-Piret equation. The relationship between the biomass, hydrogen and substrate were also evaluated. The results shown that the hydrogen is a main produce of the formation process which is a growth-associated, a high biomass is favorable to increasing the hydrogen yield and shortening lag time. The three kinetic models equation have a good coincidence with the experimental data, and can really reflect the hydrogen production process from wastewater contained sucrose. The results will provide helpful reference for the large-scale production and theory study of hydrogen production.
