چکیده انگلیسی
Thermophilic microaerobic pretreatment (TMP) has been proved to be an alternative pretreatment method during anaerobic digestion (AD) of corn straw. In this study, in order to improve the fermentation efficiency during late AD stage, improve the methane yield and volatile solid (VS) removal efficiency, a secondary thermophilic microaerobic treatment (STMT) was applied in the late AD stage of corn straw. Results showed STMT obviously improved the fermentation efficiency, methane yield and VS removal efficiency. The maximum methane yield and maximum VS removal efficiency were simultaneously obtained when the oxygen loads during STMT was 10 ml/g VS (VS of residual substrate). The maximum methane yield was 380.6 ml/g VSsubstrate, which was 28.45% and 10.61% higher than those of untreated and once thermophilic microaerobic pretreated samples, respectively. The maximum VS removal efficiency was 81.85%, which was 29.43% and 17.23% higher than those of untreated and once thermophilic microaerobic pretreated samples, respectively.
