An object of the present invention is to provide an ejector-coupled deodorization device using a wet photocatalyst in which odorous substances are continuously decomposed while undergoing a combination aeration of catalyst water and odor gas and a chemical recycling process using a wet photocatalyst. In other words, the present invention is a deodorizing tank 10 in which catalyst water is stored and a process gas exhaust pipe 12 is provided thereon； A pumping means (20) provided with a pump (22) and outflow and inflow lines (24) (26) to forcibly circulate the catalyst water stored in the deodorization tank (10)； An ejector unit 30 installed in the inlet line 26 of the pumping means 20 and provided to mix and aerate the catalyst water and the malodorous gas sucked from the sewage treatment unit 100； And a photocatalyst means 40 installed inside the deodorizing tank 10 and provided to decompose odorous substances by oxidation reaction with the UV lamp. When the ejector-coupled deodorization device using the wet photocatalyst is used, the odor gas is sucked by the injection pressure of the forcibly circulated catalyst water, and the odor gas is mixed and aerated in the deodorization tank, and the odor substances collected in the catalyst water by the photocatalytic oxidation reaction are continuously It has the advantage of improving odor treatment efficiency by allowing continuous operation for a long time while undergoing a complex chemical recycling process that is decomposed.본 발명은 촉매수와 악취가스의 혼합 폭기 및 습식광촉매에 의한 화학적 리사이클과정을 복합적으로 거치면서 악취물질이 지속적으로 분해처리되는 습식광촉매를 이용한 이젝터 결합형 탈취장치를 제공코자 하는 것이다.즉, 본 발명은 촉매수가 저장되고, 상부에 처리가스 배기관(12)이 구비되는 탈취조(10)； 상기 탈취조(10) 내부에 저장된 촉매수를 강제 순환하도록 펌프(22) 및 유출, 유입라인(24)(26)이 구비되는 펌핑수단(20)； 상기 펌핑수단(20) 유입라인(26)에 설치되어, 촉매수와 오수 처리부(100)로부터 흡입되는 악취가스를 혼합 폭기하도록 구비되는 이젝터부(30)； 및 상기 탈취조(10) 내부에 설치되어 UV램프와의 산화반응으로 악취물질을 분해하도록 구비되는 광촉매수단(40)；을 포함하여 이루어지는 것을 특징으로 한다.상기 습식광촉매를 이용한 이젝터 결합형 탈취장치를 이용하면, 강제 순환되는 촉매수 분사 압력에 의해 악취가스가 흡입되어 탈취조 내에서 혼합 폭기됨과
