Device and method for strengthening aerobic deep decomposition of wet garbage biogas residues

The invention provides a device and a method for intensifying aerobic deep decomposition of biogas residues of wet garbage, aiming at the treatment of dynamic aerobic composting of the biogas residues, an improved horizontal mechanical stirring technology is adopted, and an ultrahigh-temperature aerobic composting technology is introduced. The improved horizontal mechanical stirring technology comprises the step of improving a mechanical wheel shaft into a stirring device which takes the same axis as the center and consists of a plurality of impellers with different shapes. The process of introducing the ultrahigh-temperature aerobic composting comprises the following steps: at the initial stage of aerobic composting, repeatedly inoculating the biogas residue with an ultrahigh-temperature aerobic fermentation inoculant rich in extreme thermophilic microorganisms to raise the temperature of a compost body to ultrahigh temperature, introducing a water supplementing system, and adding an additive for removing NH
