Zusammenfassung:	To effectively perform denitration processing upon exhaust gas which contains heavy metals containing copper.SOLUTION: A method for processing exhaust gas containing heavy metals, which is generated by burning a raw material containing heavy metals, which contains a nitrogen oxide, and in which a copper concentration is 0.07 g/m3 or more, performs denitration processing upon the exhaust gas containing heavy metals with use of a reducing agent. The method for processing the exhaust gas containing heavy metals includes: a burning step for burning the raw material containing heavy metals; and a denitration step for adding an alcohol as the reducing agent to the exhaust gas containing heavy metals at 300-700°C.SELECTED DRAWING: Figure 1 【課題】銅を含有する重金属含有排ガスに対して脱硝処理を効果的に行う。【解決手段】重金属含有原料を燃焼することにより生じる重金属含有排ガスであって窒素酸化物を含有し且つ前記重金属含有排ガス中の銅の濃度が０．０７ｇ／ｍ３以上である重金属含有排ガスに対し、還元剤により脱硝処理を行う重金属含有排ガスの処理方法であって、重金属含有原料を燃焼させる燃焼工程と、３００〜７００℃の重金属含有排ガスに対し、還元剤としてアルコールを添加する脱硝工程と、を有する、重金属含有排ガスの処理方法を提供する。【選択図】図１
