The semi-permeable membrane covering type aerobic fermentation device comprises an excavated pit, a sealing fixing base plate is laid at the upper end of the pit, a lifting mechanism is further installed in the pit, a lifting rod of the lifting mechanism vertically extends upwards, a lifting plate is installed at the rod end of the lifting rod, and a semi-permeable membrane covering type aerobic fermentation device is installed on the lifting plate. A lifting plate is arranged on the sealing fixing base plate, an inserting rod is correspondingly installed on the upper end face of the lifting plate, an inserting hole corresponding to the inserting rod in position is formed in the sealing fixing base plate, the inserting rod correspondingly penetrates through the inserting hole and extends upwards, and the inserting rod can be driven by a lifting mechanism to move up and down in a reciprocating mode. The semi-permeable covering film is the core of an aerobic fermentation technology, can effectively prevent dust
