Abstract
The high-solids anaerobic digestion of biological municipal waste (BMW) produces both a valuable fuel production (methane) and an anaerobic digestion residue. Compost technology was chosen to treat with anaerobic digestion residue and the conclusion was. 1) The anaerobic digestion of the bio-waste as a whole worked fine during the stabilization stage, the maximum daily gas production happened on the 125th day, the maximum was 91.86L/d and TS concentration in the digestive juice was14.78%, methane concentration was about 50-55%, HRT was 20 days and the biodegradation rate was 65.28%;2) The temperature of AD residue compost entered the thermophilic phase(55°C) on day 3 of composting, lasted at least 3days, the changes in pH followed the same trend with a rise from 6.18 to 7.26 on the 14th day, he final mass loss was 30.12%, which resulted in the compost quality higher than innocuity criteria.
