Abstract

This study was conducted to evaluate the performance of methane fermentation from effluent of hydrogen fermentation reactor in anaerobic baffled reactor (ABR) and anaerobic sequencing batch reactor (ASBR). Two reactors were operated at organic loading rate of $1.0kg\;COD/m^3{\cdot}d$ and hydraulic retention time (HRT) of 20 day. Methane production rates of ABR and ASBR for start-up periods were 0.04 L/L/d and 0.19 L/L/d, respectively, whereas maximum methane production rates of ABR and ASBR were 0.25 L/L/d and 0.31 L/L/d, respectively. Removal rates of chemical oxygen demand (COD) in ABR and ASBR for start-up periods were 89% and 92%, respectively. After startup periods, removal rates of COD and volatile solids (VS) in ABR and ASBR were maintained over 90%. The specific methanogenic activity (SMA) increased as microorganism acclimated to the substrate.

본 연구는 혐기성 수소 발효 반응조의 유출수를 기질로 이용하여 anaerobic baffled reactor (ABR) 및 anaerobic sequencing batch reactor (ASBR) 형태에 따른 혐기성 메탄 발효 성능을 평가하였다. 두 개의 반응조는 유기물 부하율 $1.0kg\;COD/m^3{\cdot}d$와 수리학적 체류시간 20일에서 운전을 수행하였다. ABR과 ASBR의 초기 운전 기간에서 메탄 발생량은 각각 0.04 L/L/d와 0.19 L/L/d로 나타났으며, ABR과 ASBR의 최대 메탄 발생량은 각각 0.25 L/L/d와 0.31 L/L/d로 나타났다. ABR과 ASBR의 초기 운전 기간에서 COD 제거율은 각각 89%와 92%로 나타났다. 정상 상태에 도달한 후에는 ABR과 ASBR의 COD 및 VS의 제거율은 각각 90% 이상 유지되었다. 비메탄 활성도는 미생물이 기질에 적응함에 따라 반응조에 상관없이 증가하였다.
