Disclosed are a fluidized bed separation method and device for methanol-to-olefins quenched water. The method may subject quenched water to liquid-solid separation via a micro-cyclone separator. The method may also subject clear liquid from the micro-cyclone separator to a secondary separation via a fluidized bed separator, then sending the same to an olefin separation device, then recovering some waste heat of the quenched water, and then returning the same to a quenching tower after performing heat exchange. The method may also regenerate a separation medium by reversely feeding stripping tower purified water or quenched water, so as to release catalyst particles absorbed by the separation medium. The method may also send a catalyst slurry concentrated by the micro-cyclone separator and the fluidized bed separator to a filter-press unit for filter-press dehydration, so as to recover a catalyst.
