<p>The present invention relates to a waste water discharge system of a ship, comprising: a sewage treatment plant (STP) which discharges processing water (DB) which is purified by receiving black water (B) and grey water (G) by an exhaust pump to the outside of the ship; a grey water feeding tank and a grey water holding tank in which grey water (G) is temporarily stored through an extra fluid path away from the processing water (DB); and a waste water exhaust passage forming the fluid path capable of discharging the processing water (DB) in the internal part of the sewage treatment plant (STP) and the grey water holding tank to the outside of the ship, thereby enabling to prevent an overflow at the STP and to compact the STP.</p> |
