(목적) 본 발명은, 스크러버 배수를 일시적으로 저장하고, 스크러버 배수가 발생하지 않는 시간대에 해양에 투기할 수 있을 정도까지 오염물질농도를 저하시키는 선박배기가스의 세정배수처리장치를 제공한다. (구성) 선박배기가스를 스크러버 수로 세정하는 세정부를 구비하고 선박의 엔진에 배기가스의 일부를 재순환시켜서 배기가스 중의 질소산화물의 양을 감소시키는 배기가스 재순환유닛(1)과, 배기가스 재순환유닛(1)을 사용한 스크러버 세정운전의 시동에서부터 정지까지의 운전가동 중에 발생한 스크러버 배수를 저장하는 제1버퍼탱크(5)와, 제1버퍼탱크(5) 내의 스크러버 배수 중에서 스크러버 세정운전에 있어서 증량된 배수를 받아들여서 저장하는 EGR 드레인 탱크(13)와, EGR 드레인 탱크(13) 내의 스크러버 배수를 유입시켜서 고액분리의 정화를 하는 원심분리기(15)와, 원심분리기(15)에 의하여 정화된 스크러버 수를 더 정화하는 막장치(27)를 구비하는 것을 특징으로 한다.

    The present invention provides a cleaning wastewater treatment device for a marine waste gas, which temporally preserves scrubber wastewater and lowers a contaminant concentration to a degree capable of dumping the scrubber water in sea during a time zone when the scrubber wastewater is not generated. A cleaning wastewater treatment device comprises: an exhaust gas recirculation unit (1) having a cleaning part for cleaning ship waste gas with scrubber water, and recirculating a portion of an exhaust gas to an engine of a ship to reduce an amount of nitrogen oxide in the exhaust gas; a buffer tank (5) storing scrubber wastewater generated during the operation from the start to the stop of the scrubber cleaning operation using the exhaust gas recirculation unit (1); an EGR drain tank (13) receiving and storing the waste water increased in the scrubber cleaning operation of the scrubber waste water in the buffer tank (5); a centrifugal separator (15) introducing the scrubber waste water in the EGR drain tank (13) to perform a cleaning operation by solid liquid separation; and a membrane device (27) further cleaning the scrubber water cleaned by the centrifugal separator (15).
