Abstract
Recently, the treatment of that wastes according to increase of food waste has been a great problem of modern society for long time. This study was aimed to evaluate possibility for food waste and sewage sludge mixture treatment using pilot scale two-phase anaerobic digester. Pilot scale two-phase anaerobic digestion system was performanced at 1 : 9 mixture ratio of food waste and sewage sludge infield. The detention time of digester was 20days. The average COD and VS removal efficiencies in organic loading rate
최근에 음식물쓰레기의 증가에 따라 폐기불의 처리가 현대사회의 큰 문제로 되었다. 본 연구는 음식물 쓰레기와 하수슬러지 혼합물의 2단 혐기성소화조에 의하여 소화의 가능성을 검토할 목적으로 수행되었다. 음식물쓰레기와 하수슬러지를 1:9의 비율로 하여 파이롯트 2단 소화시스템을 사용하여 현장에서 운전하였으며, 체류기간은 20일로 유지했다.
