정화 처리되는 밸러스트수의 투과율이 변화해도, 밸러스트수에 소정의 조사량의 자외선을 조사 가능한, 밸러스트수 처리 시스템 및 밸러스트수 처리 방법을 제공한다. 밸러스트수 처리 시스템(10)은, 처리 라인(배관(34, 36))을 흐르는 밸러스트수에 자외선을 조사하는 자외선 조사 장치(23)와 제어부(100)를 구비한다. 자외선 조사 장치(23)는, 자외선을 발하는 광원과, 밸러스트수로의 자외선의 조도를 검출하기 위한 조도 센서를 포함한다. 제어부(100)는, 조도 센서에 의해 검출된 조도(I)와 자외선 조사 장치(23)를 흐르는 밸러스트수의 유량을 이용하여 산출된 조사량을 소정의 조사량으로 유지하도록, 자외선 조사 장치(23)를 제어한다. 제어부(100)는, 검출된 조사량을 자외선 조사 장치(23)의 제어에 의해 소정의 조사량으로 유지할 수 없는 경우에는, 처리 라인을 흐르는 밸러스트수의 처리 유량을 저하시킨다.

    There is provided a ballast water treatment system and method that allows ballast water which is to be purified to receive a prescribed dose of ultraviolet rays even when the ballast water varies in transmittance. A ballast water treatment system (10) includes an ultraviolet irradiation device (23) which irradiates ballast water flowing through a treatment line (a pipe (34, 36)) with ultraviolet rays, and a control unit (100). The ultraviolet irradiation device (23) includes a light source which emits ultraviolet rays, and an illuminance sensor sensing an illuminance of ultraviolet rays received by the ballast water. The control unit (100) controls the ultraviolet irradiation device (23) to maintain at a prescribed dose a dose calculated using an illuminance (I) sensed by the illuminance sensor and a flow rate of ballast water which flows through the ultraviolet irradiation device (23). When the sensed dose cannot be maintained at the prescribed dose by controlling the ultraviolet irradiation device (23), the control unit (100) reduces a treatment flow rate of the ballast water which flows through the treatment line.
