초록

본 연구는 도심지 거리 하수 악취 물질인 황화수소($H_2S$)를 제거하기 위해 맨홀에 설치해 악취를 제거하는 맨홀필터 악취제거장치의 적용 가능성을 확인하고자 하였다. 첫번째로 맨홀필터에 들어 있는 첨착활성탄의 황화수소($H_2S$) 흡착 성능 평가 결과 황화수소 제거율이 약 99.8%를 나타냈다. 두 번째로 악취제거장치 성능평가를 위해 서울특별시 대표적인 악취 발생 맨홀 4지점에서 성능을 평가한 결과, 대표적인 악취 유발물질인 황화수소($H_2S$)를 97% 이상 제거하는 것으로 확인되었다. 본 성능 평가 연구결과를 통해 맨홀필터 악취제거장치는 하수관거 맨홀에서 발생되는 악취를 제거하는 장치로써 적용 가능성이 충분한 것으로 판단된다.

The objective of this study is to evaluate the applicability of a manhole-filter odor eliminator that is installed on a manhole to remove hydrogen sulfide ($H_2S$) contained in the sewage of urban streets; $H_2S$ is the very cause of offensive odor from such sewage. An analysis of the capability of impregnated activated carbon, which is contained in the manhole filter, to adsorb hydrogen sulfide shows that some 99.8% of hydrogen sulfide can be removed. A performance evaluation of the manhole-filter odor eliminator, which was made on Manhole Section 4 known as the representative malodorous manhole section of Seoul, Korea, indicates that more than 97% of hydrogen sulfide ($H_2S$), one of typical malodor-generating substances, can be eliminated. The results and findings of the study as described above suggest that the applicability of the manhole-filter odor eliminator to eliminate offensive odor generated from sewer manholes is satisfactory.
