Production process of nitrous oxide in landfill site received incineration residue

摘要

Recently, global warming is becoming a serious problem. But there is little research on the generation of greenhouse gases from landfill, especially regarding nitrous oxide. So, we carried out experiments using landfill modeled lysimeters and shaking tests to clarify the production of nitrous oxide. The results of this research are summarized as follows; 1) In landfill mainly disposed of incineration residue, nitrous oxide is produced by biological oxidation of ammonium (nitrification), biological denitrification and chemical reduction of nitrate. 2) Nitrification and denitrification take place in the same waste layer.
