Abstract: | "Biogas residue of Spartina alterniflora treated by NaOH solution for 48h at room temperature was used for secondary anaerobic digestion with TS loading rates were 8%, 10%, 12% at (35 +/- 1) degrees C. The biogas yield, pH, and volatile fatty acid (VFA) were analyzed during the anaerobic digestion. The peak of daily gas production were 10, 14, 13 mL x g(-1) and the rates of cumulate gas production were 217, 227, 228 mL x g(-1) respectively. The methane content exceeded 65% and the lowest pH value was 7.04 during the process. The concentrations of acetic acid concentrations were 3 364, 3 286, 5 728 mg x L(-1) respectively while propionic acid and butyric acid concentrations were below 1 100 mg x L(-1). Biogas residue as a non-degradation organic compound with high potential biogas yield was decomposed slowly and no acid accumulation was not observed" |
