생활 폐기물 소각재 중 바닥재의 特性
Characteristics of the Bottom Ash in Municipal Solid Waste Incineration Ash
초록
생활 폐기물 소각재 충 바닥재를 입도별로 분급하여 그 구성물질, 화학성분과 중금속 함유량 및 용출량, 다이옥신 함유량 등의 특성을 파악하여 바닥재의 재활용 가능성을 알아보았다. 바닥재의 주요구성물질은 유리질류, 자기질류, 철질류이었으며, 입자가 커질수록 이들의 함유량이 많아져 4mesh~25mm에서는 약 70%이상을 차지하였다. 바닥재의 주요성분은 CaO,
The main consistent materials and main elements of the bottom ash in municipal solid waste incineration ash according to particle size were investigated and the environmental hazards were considered by investigating the content of dioxin and heavy metals in bottom ash and the concentration of heavy metals in its leachate. The main materials of bottom ash are glasses, ceramics, scraps of iron. As the particle size increases, their percentage weight also increases and their percentage weight was over 70% in 4 mesh~25 mm particle size fraction. The main elements of bottom ash are CaO,
