Abstract
The way to treat the increasing industrial wastes and sewage emission are now a big problem for environment Preservation.
Among these industrial wastes, sludges are the second in volume, next to the dusts and ashes so far.
Especially, the organics contained in the sludge should be decomposed into stable compounds by incineration or pyrolysis. And there, the poisonous materials decomposed or produced through the sludge incineration must be kept away from the environmental pollution.
On this point of view, this paper introduces the investigation with the pilot plant on the sludge incineration contaminated with heavy metals.
The results show us some behaviors of poisonous gases and heavy metals exper-imentally.
