<p>A UV reactor for a ship ballast water treatment apparatus according to the present invention includes a seawater inlet into which seawater flows; a body through which the seawater that flows into the seawater inlet passes; a seawater outlet through which the seawater that passes through the body is discharged; a hollow protection pipe that is arranged in the body to cross an inner portion of the body in a direction parallel to the ground surface; and a UV lamp that extends in a longitudinal direction of the protection pipe in the protection pipe, and performs UV sterilization on the seawater which passes through the body. Both open end portions of the protection pipe penetrate a wall of the body, and both end portions of the UV lamp are fixed by a bush assembly that is partially inserted into opening portions of both of the end portions of the protection pipe. The bush assembly has a fixing member that is inserted into the protection pipe and is coupled with the UV lamp; and a connection member that is fixed to the body. The fixing member can move in a longitudinal direction of the UV lamp with respect to the connection member, and elastic means for providing an elastic force in a central direction of the UV lamp is coupled between the fixing member and the connection member.</p> |
