• Study of Environmental Conditions on Sulfate Reduction in Leachate from Incinerator Ash

抄録

In Japan more than 70% of municipal solid waste (MSW) has been incinerated. Since the heavy metal content is high in incinerator ash, there is a potential hazard of releasing heavy metals to the environment. In this paper, we did experimental studies on biological sulfate reduction in leachate from ash to know the possibility of heavy metal insolubilization.<BR>In this experiment, the influence of environmental conditions on the activity sulfate-reducing bacteria (SRB) was almost the same as reported by other researchers. Once those conditions were met, sulfide was produced by SRB in leachate from ash. Sulfate reduction was stopped even though sulfate and TOC still remain in leachate, because SRB in the authors' experiment utilized mainly lactate. Only 25% of TOC was transformed into lactate.
