Abstrakt
The present research is dedicated to the study of anaerobic co-digestion process of
different biomass materials. Anaerobic co-digestion of digested sludge, grass silage, haylage and
cattle manure was evaluated in mesophilic tank reactors in the lab-scale experiment. Twelve
laboratory scale tank reactors (1.5 L) were used during the incubation period of 45 days. First
triplet of reactors was fed with pure digested sludge and the other three with different mixtures
having the volumetric ratios of 30/35/25/10, 40/30/20/10 and 50/25/15/10 for digested
sludge/corn silage/grass haylage/cattle manure. Methane production was analyzed for all labscale
reactors individually. The resulting specific methane production of above-mentioned
batches was 336.34, 238.1 and 233.23 LSTP[CH4] kg-1
[TVS], respectively. Other results such as
cumulative biogas and methane yield, volumetric biogas and methane yield, volumetric biogas
and methane yield per day were also assessed. These results had the highest meaning when
complex substrate had no more than 30% of inoculum.
