The invention discloses an integrated large micro-wave sterilization disinfection processor for medical wastes. The integrated large micro-wave sterilization disinfection processor comprises a feed hopper, a pulverizer, a micro-wave warehouse, a magnetron microwave generator, a screw shaft conveyer, a leron plate, a steam inlet pipe, a gas collecting bucket of an extractor fan, a condenser, a biological deodorization device, an exhaust fan, an exhaust funnel, a motor, a speed reducer, a slag hole, a waste compressor, a pushing motor and a machine body. The integrated large micro-wave sterilization disinfection processor takes the magnetron microwave generator as a heating source and is equipped with waste compressor and the biological deodorization device; and the processor is a medical waste processing device capable of continuous lifting, crushing, sterilizing, drying, transporting and packing. Secondary pollutants such as dioxin with strong toxicity can be avoided; steam-microwave combined sterilization means is adopted; the microwave generates an evil heat effect to quickly penetrate an object so that heat is directly generated due to friction inside molecules of an object, resulting in bacterial death. The integrated large micro-wave sterilization disinfection processor for medical wastes is suitable for intensive treatment and disposal of the medical wastes in middle-sized and small cities.
