Zusammenfassung:The present invention relates to a nitrogen oxide reduction method and nitrogen oxide reduction apparatus to reduce nitrogen oxides in exhaust gas. According to the present invention, since an aerosol containing unspecified bacteria is sprayed into a chamber without selective culturing or screening of bacteria and nitrogen oxides can be removed from exhaust gas containing nitrogen oxides by using water film and surface of the bacteria, the exhaust gas can be put into the chamber directly without pretreatment, thereby reducing processing steps. In addition, since the unspecified bacteria are used without restrictions on the type, the unspecified bacteria can be prepared easily without selective culturing or screening of bacteria, thereby providing advantages of increasing nitrogen oxide treatment speed and saving costs. The nitrogen oxide reduction method comprises an exhaust gas inflow step and an aerosol spraying step. 배기가스 내 질소산화물을 저감할 수 있는 질소산화물 저감방법 및 질소산화물 저감장치에 관한 것으로써, 박테리아의 선택적 배양이나 선별필요 없이 불특정 박테리아를 함유하는 에어로졸을 챔버내로 분사시켜, 질소산화물을 포함하는 배기가스로부터 질소산화물을 박테리아의 수막 및 표면을 사용하여 제거할 수 있으므로, 배기가스의 전처리 과정없이 바로 챔버에 투입할 수 있으므로 공정처리단계가 감소될 수 있을 뿐만 아니라, 종류에 제한 없는 불특정 박테리아를 사용하므로 박테리아의 선택적 배양이나 선별이 필요 없이 손쉽게 준비할 수 있으므로, 질소 산화물 처리 속도와 비용이 절약될 수 있는 장점이 있다.
