The invention discloses a treatment system for combining the emergency treatment of kitchen waste with an incineration plant, and relates to the field of waste treatment. The treatment system for combining the emergency treatment of the kitchen waste with the incineration plant comprises a waste incineration plant discharging hall and a kitchen waste emergency treatment workshop, wherein the kitchen waste emergency treatment workshop is arranged below the waste incineration plant discharging hall; the kitchen waste emergency treatment workshop comprises a feeding cabin, a bag breaking machine, a screw press, a pyrolysis device, a three-phase separator and a grease storage tank. By using the treatment system for combining the emergency treatment of kitchen waste with the incineration plant, swill-cooked dirty oil is prevented from entering a food chain; the pressure of a sewage treatment system is decreased; the harmlessness and the reclamation of the treatment of the kitchen waste can be realized better; meanwhile, the treatment system for combining the emergency treatment of the kitchen waste with the incineration plant is reasonable in layout; project construction land is greatly reduced; the project investment cost is decreased.
