영문 초록

Thís study was made to evaluate the temperature effects on anaerobic digestion of swine manure. A laboratory single-stage , high-rate , anaerobic digester was operated at 10, 20 and 30 day’s HRT at the temperature of 35 0C or 550 C. The conclusions from this study are as follows: (1) COD and BOD reductions were similar in both the mesophilic and thermophilic digestions. (2) With thermophilic digestion, volatile reduction increased to 67%, as compared with 60% of mesophilic digestion. (3) With thermophilic digestion , the pH increased to 8.5 as compared with 8.0 of mesophilic digestion. (4) With thermophilic digestion, the concentration of volatile acid increased to 763 mg/l, as compared with 250 mg/l of mesophilic digestion. (5) While the gas was produced by mesophilic digestion at 0.74m3 !kg of VS fed , it increased to 0.87m3 !kg VS fed by thermophilic digestion. (6) The refractory VS was about 25% of the influent VS.
