摘  要:
The investigation of the biodegradability and methane potential of bacterial pre-treated miscanthus sinensis has been carried out. One percent golution of Bacta-sile: A silage promoter was used to pre-treat miscanthus sinensis at 25 degrees C. The anaerobic digestion experiments were carried out at 25 degrees C and 35 degrees C in batch experiments. The organic loading rates (OLR) varied between 1.25 g and 7 g in different batch reactors. The results showed that the highest methane concentration was 57% from digester 1 while the lowest methane produced was 38% from digester 3. The low methane production from digester 3 was attributed to temperature changes and poor organic loading rate. Bacterial pretreatment aided biodegradation of miscanthus at 25 degrees C. Operating temperature of 25 degrees C had a great effect on digestion experiments resulting to longer required Hydraulic Retention Time (HRT).
