초록
혐기성 소화효율의 극대화를 위해 온도상분리 공정과 혐기성 회분식 공정을 음식물 쓰레기와 하수슬러지의 혼합기질에 적용한 온도상분리 혐기성 회분식 소화공정(TPAD-ASBR)의 거동 특성을 유기물부하의 변화에 따라 평가하여 다음과 같은 결론을 얻었다. TPAD-ASBR 과 대조구의 첫 단에서 대부분의 메탄생성과 유기물 제거가 이루어졌으며, 단위부피당 메탄발생량은 유기물부하 2.7 g VS/L/d에서 각각 0.79와 0.59L
Temperature-phased anaerobic digestion (TPAD), anaerobic sequencing batch reactor (ASBR), and co-digestion technologies were combined together in order to overcome low efficiencies of conventional anaerobic sewage sludge digestion processes. In the performance, TPAD-ASBR process showed high VS removal efficiency over 60% up to the organic loading rate (OLR) of 2.7 g VS/L/d. The first-stage of TPAD-ASBR and control system played a most significant role in VS destruction and methane production. Methane production rate (0.79 l
