Abstract
This study was conducted to evaluate effects of gas retention time and filling depth of a compost-based biofilter on removal of vapor phase gasoline and to suggest operational improving method. Gas empty bed retention times(EBRTs) were 4, 10, and 20 minutes, respectively. EBRT of over 10 minutes was required in both cases of TPH(total petroleum hydrocarbons) and BTEK (bezene, toluene, ethylbenzene, and xylene). Filling depths were 25, 50, 75, and 100cm, respectively. To treat gasoline TPH effectively, controlling other operational parameters including EBRT and gas loading rate was more important than increasing filling depth simply. 1m filling depth was sufficient in treating BTEX without controlling other operational parameters greatly.
본 연구는 가솔린 휘발가스를 퇴비 바이오필터로 처리시 공정조절 인자인 체류시간과 충전깊이의 영향을 살펴보고 공정개선방안을 제시하고자 실시하였다. 체류시간을 4, 10, 그리고 20분으로 변화하여 실시한 결과 TPH의 효율적 제거를 위해서는 10분이상의 EBRT가 요구되었으며
