NOVELTY - The aerobic-anaerobic solid fermentation device joint comprises a central solid anaerobic fermentation bed (2), and a solid aerobic fermentation bed (1), between which a heat conducting board is arranged. The solid anaerobic fermentation bed is present at the bottom of an anaerobic sludge return-flow system (9), through the solid anaerobic fermentation bed, where the tail end is divided into two paths, from top to bottom, and is connected to the solid anaerobic fermentation bed and solid aerobic fermentation bed. The top part is provided with a gas collecting system (6).    USE - The aerobic-anaerobic solid fermentation device joint is useful for drying and composting industrial biomass waste.    ADVANTAGE - The aerobic-anaerobic solid fermentation device joint is simple, easy, cost effective and environmental friendly with high enzyme activity and no waste water discharge.    DETAILED DESCRIPTION - The aerobic-anaerobic solid fermentation device joint comprises a central solid anaerobic fermentation bed (2), and a solid aerobic fermentation bed (1), between which a heat conducting board is arranged. The solid anaerobic fermentation bed is present at the bottom of an anaerobic sludge return-flow system (9), through the solid anaerobic fermentation bed, where the tail end is divided into two paths, from top to bottom, and is connected to the solid anaerobic fermentation bed and solid aerobic fermentation bed. The top part is provided with a gas collecting system (6), and a power supply system (8) is connected with the gas collecting system. A heat supply pipeline passes through the solid anaerobic fermentation bed, from top to bottom, and is uniformly distributed on an inner wall of the solid anaerobic fermentation bed. The solid anaerobic fermentation bed is connected with the solid aerobic fermentation bed, which is provided with a supporting structure. The anaerobic sludge return-flow system comprises an anaerobic sludge refluxing pipe, a sludge pump and the anaerobic sludge discharge pipe. The solid anaerobic fermentation bed top part is provided with a feeding port, and the bottom taper is connected with the anaerobic sludge discharge pipe. The solid aerobic fermentation bed comprises a charging, and inoculation area and aerobic fermenting bed stirring system along the bottom of the discharge hole and fermenting bed. The aerobic fermenting bed stirring system of the platform is provided with a saw tooth groove track. The platform and a horizontal walking wheel is driven along the saw tooth grooves of horizontal walking motor, where the horizontal walking and lower platform is equipped with scraper stirrer driven by the stirring motor and bottom platform is equipped with a guide wheel. The horizontal walking motor and a stirring motor are fixed on the stirring system. The scraper stirrer is connected to the stirring system platform by the scraper supporting frame passing through the lower end of the halyard front, and the scraper stirrer is provided with tooth. An INDEPENDENT CLAIM is included for a method of making an aerobic-anaerobic solid fermentation device joint.
