چکیده انگلیسی
The feasibility of corn stalk anaerobic digestion was investigated in an upflow anaerobic solid-state (UASS) reactor with an additional anaerobic filter (AF) reactor. One single-stage (UASS) and two two-stage systems (UASS + AF) were compared at organic loading rates (OLR) of 2.5, 4.5, and 8.0 gvs Lâ1 dâ1. The single-stage system was operated under mesophilic conditions and the two-stage systems under both mesophilic and thermophilic conditions. Independently of OLR, the mesophilic two-stage system showed higher average methane production rates (0.50 ± 0.01, 0.63 ± 0.11, and 0.67 ± 0.12 LCH4L-1d-1) than the single-stage (0.46 ± 0.02, 0.46 ± 0.06, and 0.31 ± 0.09 LCH4L-1d-1) and thermophilic two-stage (0.30 ± 0.02, 0.42 ± 0.05, and 0.66 ± 0.12 LCH4L-1d-1) systems. Respective methane yields were 84-201, 39-184, and 88-119 mL gvsâ1. The observed advantage of mesophilic digestion is of particular interest, as degradation of lignocellulosic biomass is usually reported to benefit from higher temperature. The results show the general feasibility of an additional AF reactor after the UASS digestion of corn stalk under mesophilic conditions.
