چکیده انگلیسی
In this study, the effects of Intermittent-Vacuum Stripping (IVS) on activities of methanogenesis in co-digestion of corn stover with liquid swine manure (LSMâ¯+â¯CS) under thermophilic anaerobic digestion (TAD) conditions were evaluated. A 65% methanogenesis activity inhibition was observed in pretreated LSM plus corn stover (pLSMâ¯+â¯CS), while 60 and 165â¯mL/L/day CH4 productions were achieved in pLSMâ¯+â¯CS and LSMâ¯+â¯CS, respectively. The high salinity condition (5.28%) after IVS pretreatment was considered the primary inhibitor in pLSMâ¯+â¯CS, while the ammonia (â¤600â¯mg/L), C:N ratio (15.52) and volatile solid loading rate (3â¯g/kgâ1·dayâ1) didn't show a negative effect on CH4 production. When salinities were increased from 2% to 4% and 8%, 50% and 100% inhibition were observed respectively. The butyrate accumulation was a potential indicator of the non-salinity-inhibition status for methanogenesis in TAD.
