매립은 비록 환경오염을 초래하긴 하지만 폐기물관리에 있어서 대체가 불가능한 기술로 남아 있다. Site aeration은 이러한 문제를 완화하기 위하여 효과적인 것으로 나타났다. 폭기를 증진시킴으로써 매립지 내에서의 자연적 방출을 통하여 폐기물을 안정화시키기 위하여, 산소소비율과 투기성 및 확산은 수직파이프를 설치 및 설계하는 데 고려해야 할 주요한 인자가 된다. 본 논문은 일본에서 매립된 다양한 생쓰레기, 즉, 소각재, 불연성폐기물, 분쇄된 조대 폐기물 등의 산소소비율을 조사하는데 그 목적을 두고 있다. 산소소비율의 실험결과는 수학적 모델에 적용될 것이다. 모사된 오래된 폐기물(용출과정을 거친 생쓰레기) 뿐만 아니라 실제로 오래된 매립지에서 얻어진 오래된 폐기물도 같은 실험과정을 거쳤다. 얻어진 결과는 공기흐름과 폭기된 매립지 내부의 이동을 모사하기 위한 연구에 적용 가능할 것이다. Landfilling remains an irreplaceable technique for waste management, although the damage it cause to the environment. Site aeration proved to be effective to attenuate these problems. Oxygen consumption rate and air permeability/diffusion are the major parameters to set up the best allocation and design for vertical pipe, in order to promote aeration, hence stabilization of waste, through natural ventilation inside landfill site. This paper works on investigating the oxygen consumption rate for a variety of fresh waste (Municipal Solid Waste (MSW) landfilled in Japan, i.e. incineration ash, incombustible waste and shredded bulky waste). The experimental data of oxygen consumption rate will be fitted to a mathematical model. Old waste (brought from old landfill site) as well as simulated old waste (leached fresh samples) were subjected to the same tests. Obtained results will be used for a further work simulating air flow and transfer inside aerated landfill sites.
