Experiment for the Treatment of Sludge and High Calorific Waste In Fluidized-Bed Gasifying Melting System

Abstract

This paper reports the mixing treatment test of MSW with excrement sludge or waste plastics in 10t/day demonstration plant of the fluidized-bed gasifying melting system in order to confirm the applicability of various wastes. MSW and sludge were mixed at 80 : 20,and MSW and plastics were mixed at 70 : 30. It was confirmed that these mixtures were treated properly as MSW is treated. It was also confirmed that the pollution in the mixing treatment of MSW and sludge or plastics was prevented at such the level as the pollution of the treatment of the MSW only. Especially, in the treatment of MSW and plastics, which contains comparatively large amount of chlorine, the level of the dioxins concentration in exhaust gas and fly ash was low enough to clear the standards of the law.
