Multi-phase continuous separating method applicable to aqueous phase oil extraction

The invention provides a multi-phase continuous separating method applicable to aqueous phase oil extraction, wherein the method includes steps of making oil grease enter a water phase after smashing, alkaline extraction or enzymolysis of an oil material, and forming a multi-phase mixing system; after settling the system, layering oil, emulsion, and slag part; performing two-phase separation on residue with a few amount of water phase at the lower settling layer; then performing the two-phase separation on the water phase, and acquiring emulsion and water phase; performing three-phase separation on the oil, emulsion and a part of water phase at the upper settling layer, and acquiring clean oil, water phase and a few amount of emulsion fluid; performing enzymic method demulsification on the emulsion fluid at the upper layer and the lower layer; then performing the two-phase centrifugal separation, and acquiring clean oil and water phase. The multi-phase continuous separating method can realize the multi-phase
