The invention relates to an integrated process system for demulsification separation, drying and viscosity reduction and pyrolysis return of oily sludge by a microwave method. A demulsification separation system of the system comprises a microwave demulsifier, a horizontal type settling oil-sludge-water three-phase separator and the like. A drying and viscosity reduction system comprises a microwave drying unit, a microwave viscosity reduction unit and the like. A pyrolysis return system comprises a microwave continuous-pyrolysis furnace, a pyrolysis coke return unit and the like. Oily sludgeenters the microwave demulsification separation system, is subjected to microwave radiation demulsification and oil sludge water three-phase separation, bottom oily sludge is delivered to the drying and viscosity reduction system through a slurry pump, the dried and viscosity-reduced oily sludge is delivered to the microwave continuous-pyrolysis furnace through a screw conveyor for pyrolysis, andpyrolysis coke participate
