Environment-friendly treatment method for realizing efficient utilization of kitchen waste

The invention relates to the technical field of advanced treatment of kitchen waste, in particular to an environment-friendly treatment method for realizing efficient utilization of kitchen waste, which comprises the following steps: putting waste into a pool, and carrying out primary waste standing layering; primarily screening light floating objects; carrying out a multi-stage mesh lifting and screening process; stirring and crushing to form crushed garbage mixed liquid; treating by using fine grizzly screen equipment; carrying out secondary standing layering treatment; the water-oil mixture and the deposited food waste mixed liquid in the three layers of standing layered materials are conveyed to the downstream from different flow directions respectively; re-separating oil and water; the three-phase separator is used for carrying out three-phase separation on water, oil and slag slurry; the water obtained after the three-phase separation of the water, the oil and the residue slurry is second-stage water li
