According to an embodiment of the present invention, an apparatus for treating air pollutants is provided. According to the embodiment of the present invention, the apparatus for treating air pollutants comprises: a scrubber supplying wash water to an exhaust gas supplied from a combustion engine to make gas-liquid contact therebetween; an oxidation catalyst storage tank storing an oxidation catalyst injected into the scrubber to oxidize the exhaust gas and prevent the reduction of the oxidized exhaust gas; a wash water storage tank connected to the scrubber through a wash water discharge pipe and storing the wash water and the oxidation catalyst discharged from the scrubber; a wash water circulation pipe connecting the wash water storage tank and the scrubber to circulate, to the scrubber, a portion of the mixture of the wash water and the oxidation catalyst stored in the wash water storage tank; a neutralizer supply unit supplying a neutralizer to the wash water storage tank; a salt separation unit connected to the wash water discharge pipe at a rear end of the wash water storage tank, and including a capacitive deionizer electrically adsorbing salts generated by a reaction between the wash water and the neutralizer in the wash water storage tank to separate the same from the wash water; and a reclaimed water supply pipe supplying pure water to the salt separation unit as reclaimed water to desorb the salts adsorbed by the capacitive deionizer. The salt separation unit can receive the mixture of wash water and the oxidation catalyst or the reclaimed water from any one of the wash water discharge pipe and the reclaimed water supply pipe.

    본 발명의 일 실시예에 의해 배기 오염물질 처리장치가 제공된다. 본 발명의 일 실시예에 따른 배기 오염물질 처리장치는, 연소기관으로부터 공급되는 배기가스에 세정수를 공급하여 기액 접촉시키는 스크러버와, 스크러버 내부로 분사되어 배기가스를 산화시키고 산화된 배기가스의 환원을 방지하는 산화촉매를 저장하는 산화촉매저장탱크와, 세정수배출관을 통해 스크러버와 연결되어 스크러버에서 배출되는 세정수와 산화촉매를 저장하는 세정수저장탱크와, 세정수저장탱크와 스크러버를 연결하여, 세정수저장탱크에 저장된 세정수와 산화촉매의 혼합액 중 일부를 스크러버로 순환시키는 세정수순환관과, 세정수저장탱크에 중화제를 공급하는 중화제공급부와, 세정수저장탱크 후단의 세정수배출관에 연결되며, 세정수저장탱크 내부에서 세정수와 중화제가 반응하여 생성된 염을 전기적으로 흡착하여 세정수로부터 분리하는 축전식 탈이온장치를 포함하는 염분리유닛, 및 염분리유닛에 청수를 재생수로 공급하여, 축전식 탈이온장치에 흡착된 염을 탈리시키는 재생수공급관을 포함하되, 염분리유닛은 세정수배출관과 재생수공급관 중 어느 하나로부터 세정수와 산화촉매의 혼합액 또는 재생수를 공급받을 수 있다.
