초록
활성탄/폴리우레탄 복합담체를 충전한 바이오필터를 사용하여 기상톨루엔의 처리 실험을 약 120일간 수행하였다. 미생물 균주는 Bacillus sp.를 사용하였다. 톨루엔의 유입 농도 및 공탑접촉시간(EBCT)과 같은 운전인자가 제거효율에 미치는 영향을 검토하였다. 120일 동안 운전 중 바이오필터 컬럼내의 압력손실과 pH의 변화 등을 살펴보았다. 또한, 유입되는 톨루엔 가스, nutrient 및 톨루엔 가스와 nutrient가 동시에 12 h 간격으로 공급/중단되는 경우에 바이오필터의 제거능을 조사하였다.
The treatment of toluene vapor was carried out using the biofilter packed with activated carbon/polyurethane composite during 120 days. Bacillus sp. was used as a toluene oxidizer. The effects of operating conditions such as the influent toluene concentration and the empty bed contact time (EBCT) on the removal efficiency of toluene were investigated. During 120 days operation, the pressure drop through the biofilter column and the pH change in the drain water were observed. When toluene vapor, nutrient, and both toluene vapor and nutrient were supplied and stopped at 12 h interval, the performance of the biofilter was also studied.
