The invention discloses a ship wastewater treatment system, which is used for treating desulfurization wastewater generated by a ship desulfurization system and comprises a feeding unit, a filtering unit and a separating unit. The feeding unit comprises a waste water pipeline used for receiving desulfurization waste water. The filtering unit is communicated with the feeding unit so as to receive the desulfurization wastewater, the filtering unit comprises a ceramic membrane filter used for separating the desulfurization wastewater into filtrate and concentrated solution, and the filtering unit further comprises a filtrate discharging pipeline communicated with the ceramic membrane filter so as to discharge the filtrate; and the separating unit is communicated with the filtering unit to receive the concentrated solution, the separating unit comprises a flocculation device and a separating device, the flocculation device is used for flocculating the concentrated solution to form a flocculated solution containing solids, and the separating device is used for separating the flocculated solution to form sludge and a separated solution. The ship wastewater treatment system disclosed by the invention is easy to maintain, stable in effect and capable of meeting the emission standard; the desulfurization wastewater is firstly filtered and then flocculated, so that the ceramic membrane filter can be protected.
