과열증기 반응에 의한 생활폐기물 유기성분 입도특성 = Characteristics of Particle Size Distribution in the Organic Fraction of Municipal Solid Waste by the Reaction of Super-heated Steam

국문 초록 (Abstract)

최근, 국내에서 MBT(Mechanical Biological Treatment) 처리시설이 건설되어 운영 중에 있으며, 생활폐기물 등이 분리선별되어 재활용되고 있다. 그러나, 생활폐기물의 입도가 불균질하고, 분리선별을하기 위해서 일정입도 이하로 파쇄하여야 하므로 운영상의 문제점이 발생하게 된다. 또한, 생활폐기물내 유기성분의 분리선별이 어려워서, 재활용 물질의 이용이 어려운 실정이라 이에 대한 대책이 요구된다. 본 연구에서는 1ton/batch 규모의 반응기에 과열증기를 사용하여 각 반응인자에 따른 생활폐기물분리선별 효율을 파악하였으며, 유기성분 분해에 따른 생활폐기물 입도특성의 변화를 고찰하였다.

다국어 초록 (Multilingual Abstract)

Recently, MBT(Mechanical Biological Treatment) facilities were built up and operated to separate and recycle MSW(Municipal Solid Wastes)in South Korea. However, the size distribution of MSW is very rough, and it is causing operation problem because MSW would be crushed in undersize diameter by mechanical equipment before feeding each seperation process. Also, the organic material should be pre-seperated to reuse recycle material in MSW. In this research, the reactor of 1ton/batch using the super-heated steam was tested to present the separation efficiency and the size distribution of MSW by experimental factors.
