The present invention relates to a sterilizing apparatus using a sterilizing resin, and more particularly, to a sterilizing apparatus using sterilizing resin, in which raw water introduced through an inlet is discharged to an outlet, And a sterilizing resin layer disposed at a rear end of the strainer in the first pipe and filled with a triiodide resin, wherein the sterilizing resin layer is disposed in the inlet pipe, The raw water introduced into the first pipe is sterilized while passing through the sterilization resin layer through which foreign substances contained in the raw water are filtered through the holes of the strainer.According to the present invention as described above, the sterilizing device is simply connected to the existing pipe to which the raw water is supplied, so that it can be used for a long period of time without clogging the strainer and the filtering net by the foreign substances included in the raw water, It is possible to sterilize the sterilized resin layer filled with the odadic resin, thereby reducing the investment cost of the facility by a simple structure. In addition to the supply of agricultural water, drinking water, or facilities such as a swimming pool and a swimming pool, So that it can be used in any place, so that the use range has a wide effect.In addition, a propeller body rotatable by the flow of raw water is provided at the rear end of the strainer without providing additional power to the strainer, so that the strainer is rotated together with the propeller body to remove foreign substances adhered to the surface, The strainer is washed periodically by connecting the pipe to which the washing water is supplied, so that the maintenance is very convenient.본 발명은 살균수지를 이용한 살균장치에 관한 것으로서, 보다 상세하게는 유입구를 통해 도입되는 원수가 유출구로 배출되는 제1배관과, 다수개의 구멍이 형성되는 전협후광 형상으로 상기 제1배관의 내측에 설치되되, 전단부가 상기 유입구를 향하도록 배치되는 스트레이너와, 상기 제1배관 내부에서 상기 스트레이너의 후단에 설치되되, 내부에 트리이오다이드 수지가 충진되는 살균수지층을 포함하여, 상기 유입구를 통해 상기 제1배관 내부로 도입되는 원수가 상기 스트레이너의 구멍을 통해 원수에
