NOVELTY - Column type anaerobic and aerobic integral fermenting device comprises a fermenting tank, an air storage bag, an air compressor, an electrical heater and a pipe. The fermenting tank includes a double-layer tank body, a thermal insulating layer and a top cover. A sieving plate is horizontally mounted in the tank body, where the upper layer of a sieving plate has a fermenting cabin, and the lower layer has a gas buffer chamber and a filter liquid storage pool. The tank body is a double-layer columnar bowl-shaped body, and the thermal insulating layer is mounted between two layers.    USE - Used as a column type anaerobic and aerobic integral fermenting device.    ADVANTAGE - The device: integrally processes the biogas residue to produce organic fertilizer, which is directly used to make the fermenting system continuously and stably produce methane and/or the organic fertilizer; and includes the thermal insulating layer for starting the anaerobic fermentation under low temperature condition and controlling the process temperature.    DETAILED DESCRIPTION - Column type anaerobic and aerobic integral fermenting device comprises a fermenting tank, an air storage bag, an air compressor, an electrical heater and a pipe. The fermenting tank includes a double-layer tank body, a thermal insulating layer and a top cover. A sieving plate is horizontally mounted in the tank body, where the upper layer of a sieving plate has a fermenting cabin, and the lower layer has a gas buffer chamber and a filter liquid storage pool. The tank body is a double-layer columnar bowl-shaped body, and the thermal insulating layer is mounted between two layers. The feeding and discharging ports on the upper end of the tank body are fixedly connected to the top cover in a sealing mode. An air exit is arranged on the top cover, and an air inlet is mounted on the lower end of the tank body. The air exit is connected to the air storage bag, which is connected with the air compressor and the electrical heating machine by the pipe. The electrical heating machine is connected to the air inlet on the lower end of the tank body, and a valve on the air storage bag is connected to the air storage tank by the pipe. Multiple temperature probes are mounted on the inner wall of the tank body, and the methane is arranged in the air storage bag. The air compressor, the electrical heating machine and the power source are connected to each other.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the column type anaerobic and aerobic integral fermenting device.
