NOVELTY - Processing edible fungus residue comprises taking fungus bag, removing the plastic envelope, crushing the edible fungus residue bag to make the edible fungus residue into a loose form, mixing edible fungus residue with crushed maize straw or fresh excrement, adding water and stirring to obtain a mixed material, stacking the mixed material, covering by using a thin plastic film or a plastic cloth for retting to obtain edible fungus residue fermenting raw material, adding into an anaerobic reactor, adding inoculum, water and a complex microbial agent, stirring, and sealing the reactor.    USE - The method is useful for processing edible fungus residue.    ADVANTAGE - The device: comprises inclined stirrer for conveniently charging and discharging the fungus residue raw material, which avoids crusting; produces methane, which is used for power generation or agriculture, produces biogas residue, which is used for manufacturing organic fertilizer, and produces methane liquid, which is used as a foliar fertilizer for fruits or vegetable; is suitable for edible fungus producing area; and matches with green house solar panels and solar heat supply device. The method supports the use of complex microbial agent, and utilizes anaerobic reactor, which can be used throughout the year.    DETAILED DESCRIPTION - Processing edible fungus residue comprises: (i) taking fungus bag, removing the plastic envelope, crushing the edible fungus residue bag to make the edible fungus residue into a loose form, whose water content is 50-60 wt.%; (ii) mixing the edible fungus residue with crushed maize straw or the fresh excrement when the carbon to nitrogen ratio of the processed edible fungus residue is less than (20-30):1 for making the carbon to nitrogen ratio to be (20-30):1, adding water and stirring uniformly for the water content to be 60-80%, directly adding water and uniformly stirring for the water content to be 60-80% when carbon to nitrogen ratio of the edible fungus residue is equal to (20-30):1 to obtain a mixed material; (iii) stacking the mixed material into a material stack, covering by using a thin plastic film or a plastic cloth for retting, where the retting time is 5-9 days to obtain edible fungus residue fermenting raw material; (iv) adding the edible fungus residue fermenting raw material after retting into an anaerobic reactor, adding the inoculum (10-15% of the volume of the anaerobic reactor), adding water till 80% of the volume of the anaerobic reactor for the solid content of the material in the anaerobic reactor to be 10-12 wt.%, and adjusting the pH to 7.2-7.5; and (v) adding a complex microbial agent (0.5-1.2 kg complex microbial agent/ 10 cm3 of anaerobic reactor) into the anaerobic reactor, stirring uniformly, and sealing the upper opening of the anaerobic reactor by using the red mud plastic cover. An INDEPENDENT CLAIM is also included for a device for processing edible fungus residue, comprising an anaerobic reaction device, a methane desulfuration device, a gas storage device and a methane usage device. The anaerobic reaction device comprises an anaerobic reactor, a greenhouse and a solar energy heat collecting device. A red mud plastic cover is coated on the upper part of the anaerobic reactor. An inclined stirrer and an inner heat channel are arranged in the anaerobic reactor. The inner heat channel is respectively connected with multiple ring-shaped tubes connected with the pool wall. The ring-shaped tubes are completely distributed on the pool wall of the anaerobic reactor. The greenhouse is built on the outer part of the anaerobic reactor. The solar energy heat collecting device is arranged on the outer part of the greenhouse. A solar energy heat supplying pipeline is arranged on the bottom part of the solar energy heat collecting device, and connected with the water inlet of the inner heat pipeline of the anaerobic reactor. The water outlet of the inner heat pipeline of the anaerobic reactor is connected with the solar energy heat collecting device through a water reflowing pipe. A methane outlet arranged on the top part of the anaerobic reactor is connected with the methane outlet pipe.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the device for processing edible fungus residue.
