O-04　乾燥下水汚泥の熱分解・燃焼特性とリンの挙動

抄録

Climinate change caused by global warming becomes currently major problem. We need alternative energy of traditional fossil fuels to solve this problem. Biomass is one of the solutions. Sewage sludge, one of the biomass, has potentials as fuels and fertilizer due to its large amount and phosphorus content. However, since the calorific value is very low, it is rarely used as industrial energy sourse. In this study, to increase the use of sludge as fuel, we investigate the pyrolysis and combustion characteristics of sewage sludge. In addition, we analyzed the phosphorus contained in sewage sludge ash and pyrolysis residue.
