Abstract

Environmental issues are being paid more attention due to income growth, urban overcrowding, and population growth in Korea. Among the various environmental problems, odor damage is the one of the serious factors. To take example for food waste combination treatment in Su-young wastewater treatment plant in Busan, many complaints occurred because this plant locate around residential areas. The purpose of this work is not only to analyze odorous elements and their contributions but also to evaluate odor quotient (OQ), sum of odor quotient (SOQ), and treatment efficiency of bio-filter. The results of dilution sensory test of complex odor, grinder, leachate, hopper indicated higher order complex odors happen in July and August. The main odorous elements consisted of hydrogen sulfide, ammonia, methly mercaptan and acetaldehyde, which were analyzed by instrumental detection method, and methyl mercaptan was exceeded over 3,571 times of threshold. In addition, result of contribution of odor was methyl mercaptan (49.95 to 59.08%), hydrogen sulfide (20.43 to 29.27%), trimethylamine (8.82 to 13.42%) and acetaldehyde (9.17 to 11.35%). Other facilities were compared with the contribution of the odor using OQ and SOQ during the process. Sulfur compounds, acetaldehyde, and trimethylamine are high contribution of odor using OQ as well as odor intensity of grinding process is highest. As a result, sulfur compounds (e.g., methyl mercaptan and hydrogen sulfide) are highest for OQ and SOQ of grinding process is highest as 7,067. The removal efficiency of deodorization equipment was more than 90.00% in ammonia and amines, but the average efficiency of sulfur compounds was 53.51%. Thus, this facility is more higher contribution of acetaldehyde and trimethylamine than other treatment facilities. And food waste treatment in environmental area needs to consider appropriate capacity and refers to other bio-filter operating conditions.

우리나라는 소득증가, 도시집중화, 인구증가로 인해 환경적인 문제에 대해 점점 관심이 증대되고 있으며, 이러한 다양한 환경문제 중 악취로 인한 피해는 심각한 환경문제 중 하나이다. 부산시 수영하수처리장 내 음식물처리장은 음식물과 하수를 병합처리하는 시설로 주거지역 인근에 위치해 있어 많은 민원이 제기되고 있는 실정이다. 이에 본 연구에서는 악취물질분석과 기여도를 악취지수(odor quotient, OQ)와 총악취지수(sum of odor quotient, SOQ)를 평가하여 분석하였으며, 또한 후처리시설인 바이오필터의 효율을 평가하였다. 공기희석관능법에 의한 복합악취 측정결과, 7월과 8월에 분쇄기, 투입호퍼, 침출수 순으로 복합악취가 높은 것으로 나타났다. 기기분석법을 이용해 분석한 결과, 황화수소, 암모니아, 메틸메르캅탄, 아세트알데히드에 의한 영향이 가장 큰 것으로 나타났고, 메틸메르캅탄의 경우, 최소감지농도를 3,571배 이상 초과한 것으로 나타났다. 또한 악취기여도평가에서 메틸메르캅탄(49.95~59.08%), 황화수소(20.43~29.27%), 트리메틸아민(8.82~13.42%), 아세트알데히드(9.17~11.35%)순으로 기여도가 높은 것으로 나타났다. 다른 시설과의 기여도를 비교분석한 결과, 황화합물(메틸메르캅탄, 황화수소)의 OQ가 가장 높았으며, 분쇄기에서 SOQ가 7,067로 가장 높은 것으로 분석되었다. 또한 황화합물과 아세트알데히드, 트리메틸아민의 악취기여도가 분쇄공정에서 가장 높은 것으로 나타났다. 본 연구시설의 후처리시설에 대한 처리효율을 평가한 결과, 암모니아, 아민류는 90.00% 이상의 처리효율을 보였으나, 황화합물류의 처리효율은 평균 53.51%로 나타났다. 종합적으로 본 시설은 기타 처리시설에 비해 아세트알데히드와 트리메틸아민의 기여도가 상대적으로 높은 것으로 나타났다. 또한 음식물처리장의 후처리시설은 복합적인 악취성분 처리 시 분해효율이 감소할 수 있어 적절한 용량 및 운전조건에 대한 검토가 필요하다.
