초록

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. $3.03kg\;TCOD/m^3day$의 유기물 부가에서 COD와 VS 제거효율이 57.7%와 47.7%를 보였으며, 가스 생성율과 메탄의 함량은 $0.4m^3/kg$ vs.day와 65.3%로 나타났다. 이러한 결과로부터 하수슬러지와 음식물쓰레기의 혼합처리가 효과적인 것으로 밝혀 졌다.

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 $3.03kg\;TCOD/m^3-day$ were 57.7 and 47.7%, and the gas production rate and methane content were $0.4m^3/kg$ VS-day and 65.3%, respectively. TS, VS and VS/TS(%) of mixing tank were 4.44%, 2.59% and 58.34%, respectively and TS. VS and VS/TS(%) of digester in steady state were 3.32%, 1.39% and 41.90%, respectively, Through this study. it was possible to accomplish effective mixture treatment of the sewage sludge and food waste.
