The invention provides a methanol boil-off gas treatment system for a dual-fuel ship. The system comprises a main deck, a methanol pump room and a fuel preparation room, the methanol pump room and the fuel preparation room are both located below the main deck, the main deck is provided with a ventilation mast, the methanol pump room is sequentially connected with a collecting branch pipe and the fuel preparation room through a collecting header pipe, and the collecting branch pipe is sequentially connected with a smoke barrier, a pressure vacuum valve and a methanol fuel storage cabin. The methanol fuel storage cabin is connected with a ventilation pipeline and a high-speed ventilation valve arranged on the ventilation mast; the methanol pump room comprises an injection pump, the injection pump is connected with an outboard discharging valve, fire-fighting driving water, a needle valve, a pump room check valve and a collecting header pipe, a control branch is arranged at the position close to the pump room check valve, and the fuel preparation room comprises a methanol daily cabin. And the methanol daily cabin is connected with the collection header pipe through a daily collection branch pipe and is connected with a daily ventilation pipeline and a daily high-speed ventilation valve arranged on the ventilation mast. The system is high in safety, stable in control, automatic in methanol emission, energy-saving and emission-reducing.
