| Outline of Final Research Achievements |
Effects of microwave pretreatment of dewatered sludge on anaerobic digestion was examined. Although biogas production potential of dewatered sludge from an oxidation process was low, that increased by 80% by microwave pretreatment. Effects of microwave was estimated to be both heat solubilization of EPS and improve of biodegradability of suspended organic matter. As a result of a continuous digestion experiment, it was demonstrated that gas yield improved by microwave pretreatment.
