NOVELTY - Harmless recycling of domestic waste, comprises: (a) spraying effective microorganisms (EM) diluent on the domestic waste field, deodorizing and preventing mosquitoes and flies breeding; (b) sorting and crushing the domestic waste, removing insoluble impurities and crushing; (c) setting a fermentation processing device of the domestic waste; (d) conveying the waste to the anaerobic fermentation cylinder opening via the conveyor belt, and then spraying EM diluent; (e) anaerobically fermenting; and (f) aerobically fermenting for 25-30 hours to obtain biological organic fertilizer.    USE - The method is useful for harmless recycling of domestic waste.    ADVANTAGE - The method utilizes the EM microbial flora which ensure quick fermentation and decomposition to form the fertilizer, can process large amount of waste, and can achieve continuous industrial production devoid of bad odor and discharge of harmful gases.    DETAILED DESCRIPTION - Harmless recycling of domestic waste, comprises: (a) spraying effective microorganisms (EM) diluent on the domestic waste field, deodorizing and preventing mosquitoes and flies breeding; (b) sorting and crushing the domestic waste, removing metal, glass, rubber, plastic, wood, fabric and other insoluble impurities in the waste, and crushing; (c) setting a fermentation processing device of the domestic waste, where the device comprises a conveyor belt, a spiral propeller, an EM sprinkler, an anaerobic fermentation cylinder, and a rotary aerobic fermentation cylinder; (d) conveying the waste in the step (b) to the anaerobic fermentation cylinder opening via the conveyor belt, and then spraying the EM diluent to the waste; (e) conveying the waste sprayed with the EM bacteria liquid by the spiral propeller to the anaerobic fermentation cylinder, squeezing, producing an anaerobic environment, and anaerobically fermenting for 30-35 hours; and (f) conveying the waste in the anaerobic fermentation cylinder to the rotary aerobic fermentation cylinder connected with the anaerobic fermentation cylinder by the spiral propeller, aerobically fermenting for 25-30 hours to obtain biological organic fertilizer. An INDEPENDENT CLAIM is also included for a device for harmless recycling of domestic waste, comprising the conveyor belt, the anaerobic fermentation cylinder arranged on the upper part of a support, the rotary aerobic fermentation cylinder connected with the anaerobic fermentation cylinder in series, a slewing mechanism of the rotary aerobic fermentation cylinder, the spiral propeller arranged at the opening of the anaerobic fermentation cylinder and the EM sprinkler set above the anaerobic fermentation cylinder opening, where the anaerobic fermentation cylinder and the rotary aerobic fermentation cylinder are in inclined arrangement on the support at 5-8 degrees angle with the ground.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for harmless recycling of domestic waste.
