(57) [Abstract] [PROBLEMS] A combination of treatment of exhaust gas containing SOx and NOx and treatment of ammonia-containing wastewater to achieve efficient, simultaneous, Provided are a method and an apparatus for treating exhaust gas that can be economically treated. SOLUTION: In a method of treating an exhaust gas in which ammonia 14 is added to an exhaust gas 18 containing sulfur oxides and / or nitrogen oxides and an electron beam 26 is irradiated 24, ammonia is added to a part or all of the added ammonia. Ammonia 12 separated from the contained wastewater 1 is used, and the ammonia-containing wastewater is one or more kinds of organic wastewater selected from human excrement excreted from humans and / or livestock, fermentation waste liquid, and food wastewater. The organic wastewater may be used as a digestion / desorption liquid 16 after anaerobic digestion of organic matter 4 and methanation 7 is performed. Further, the produced methane 7 is burned 19 as an energy source to produce the exhaust gas. It can be treated by the method for treating exhaust gas. |
