| Outline of Final Research Achievements |
Fat and oil in kitchen wastewater discharged from restaurants cause clogging and odor of sewer pipes. Therefore fat separated by oil/water separator called grease trap is periodically collected, and then disposed through dehydration, drying, incineration, and landfill. However, the disposal cost of fat are high. This study considered the treatment performance of a new kitchen wastewater system which combined anaerobic reactor and aerobic reactor. The system in lab scale was operated continuously to confirm the treated water quality and investigate the possibility of recovering methane. The result showed that the treated water quality could be less than the environmental standard. Also, the high methane partial pressure of approximately 80% was obtained.
