dc.description.abstract | 본 연구는 정읍시에서 배출되는 하수슬러지, 축산 분뇨, 음식물 쓰레기를 대상으로 Pilot-scale(100m3) 초고온 호기성 퇴비화 공정에서의 온도, pH, C/N비, 함수율, 유기물 함량, 그리고 부피 등 물리・화학적 영양 인자를 평가하였다. 각각의 대상 물질은 1차 발효(유기성 폐기물+종균)와 2차 발효(유기성 폐기물+종균+반송 퇴비)로 나누어 수행하였다. 퇴비화가 진행됨에 따라 교반과 송풍만으로 열공급 없이 온도는 1,2차 발효에서 최고온도 90~105℃가 되었다. pH, O2, CO2, NH3, 농도 변화는 전형적인 미생물에 의한 유기물 분해 양상을 보여주었으며, 다른 모든 물리・화학적 인자들은 일반 호기성 퇴비화의 성능 이상을 보여주었다. 발효가 완료된 후 퇴비의 중금속 농도는 퇴비 비료 규격 기준 농도에 적합한 것으로 나타났다. | - |
dc.description.abstract | This study was conducted to evaluate physicochemical parameters; temperature, pH, C/N ratio, water content, organic contents and volume in a pilot-scale(capacity : 100m3 ) ultra thermophilic aerobic composting. There were three types input: municipal wasted sludge, livestock manure and slurry, and food waste produced in Jung-Eb city. Each target material was carried out by the first fermentation(organic waste + seed culture) and the second one(organic waste + seed culture + recycle compost), respectively. During composting, only with supply of air and mixing, the temperature increased 90~105℃ after every mixing in both periods. The changes of pH, O2, CO2 and NH3 represented typical organic decomposition pattern by microorganisms. Also, all other physicochemical parameters of ultra thermophilic aerobic composting process showed similar or better performance than these of general aerobic composting. Heavy metal concentration of fermented compost adapted to compost fertilizer regulation standard in the heavy metal and hazardous analysis. | - |
