According to the present invention, provided is a complex exhaust gas treatment facility which includes: an oxidizer input device which inputs an oxidizer to treatment target exhaust gas to oxidize nitrogen monoxide included in the treatment target exhaust gas into nitrogen dioxide; and a reduction treatment bath which makes nitrogen dioxide included in gas passed through the oxidizer input device react with a sulfur compound to be reduced and removed, wherein the reduction treatment bath transforms the gas passed through the oxidizer input device into a form of microbubble in reduction treatment water including a sulfur compound, and sprays the same. According to the present invention, removal efficiency of nitrogen compounds can be improved. 본 발명에 의하면, 처리대상 배출가스에 산화제를 투입하여 상기 처리대상 배출가스에 포함된 일산화질소를 이산화질소로 산화시키는 산화제 투입 장치; 및 상기 산화제 투입 장치를 통과한 가스에 포함된 이산화질소를 황화합물과 반응시켜서 환원처리하여 제거하는 환원처리조를 포함하며, 상기 환원처리조는 상기 산화제 투입 장치를 통과한 가스를 황화합물을 포함하는 환원처리수 내에서 마이크로버블 형태로 변형시켜서 분사하는 배출가스 복합 처리 설비가 제공된다.
