Abstract
The distributions and characteristics of bacteria on the deodorizing biofilters were studied as a part of biofiltration research for odor gas removal. The odor gas originated from a currently operating nightsoil treatment plant were mainly nitrogenous compounds of ammonia and amines. The filter media were consisted various ratio of pine bark, nightsoil cast and compost, and were sampled before and after operation of 153 days. Before operation, the level of bacteria on nitrification agar medium, nutrient agar medium and thiosulfate agar medium were around
암모니아와 아민류가 주된 악취원인 실가동 분뇨처리장의 악취가스를 생물탈취탑에서 처리하기위한 연구의 일환으로 다양한 비율의 소나무 껍질, 분변토, 퇴비로 구성된 생물여재를 적용하는 탈취탑 여재내의 세균 분포 및 특성을 조사하였다. 153일간 사용한 탈취탑내 여재(이하 사용후)와 악취처리에 사용하지 않은(이하 사용전) 여재 각각을 대상으로 하였다. 그 결과 사용전 여재는 질산화한천 배지, 황산화한천 배지, 표준한천 배지 상에서 g당
