The base is provided with 360 degrees rotary wheel to lock the fermentation tank. Two sides of the fermentation tank are respectively provided with a feeding port and a discharging port. The fermentation tank comprises an aerobic preprocessing chamber (2) and a fermentation chamber as double reaction zone structure. Middle parts of the aerobic preprocessing chamber and the fermentation chamber are provided with one way valves that are opened on an inner wall of the fermentation tank. A baffle plate is arranged on the fermentation tank. Two interlayers are filled with heat exchange liquid and connected with a liquid inlet valve (17) and a liquid discharging valve to form a control layer through a pipeline. A center part of the fermentation tank is penetrated with a nano ceramic membrane roller. The nano ceramic membrane is connected with a gas collecting device. An aerobic and anaerobic hydrogen chamber comprises dissolved oxygen composite electrodes for measuring index of fermenting and data synchronization to a control panel. The aerobic and anaerobic hydrogen producing chamber is provided with a sampling port and a window for sampling and observing an inner part of the fermentation tank. The base is provided with a solar battery board, brackets and an energy storage power supply device. The energy storage power supply device rotates the fermentation tank through a motor to stir the solar battery material. A frequency converter is utilized to control the motor for adjusting rotating speed of the fermentation tank. The aerobic preprocessing chamber is connected with a gravity lifting device (12) through a stop ring. An end of the gravity lifting device is connected with the one way valve to allow anaerobic hydrogen from anaerobic hydrogen generating chamber by a single direction. The aerobic preprocessing chamber is covered with a heat exchange liquid mixing tank to carrying out heat exchange of liquid, flow rate control and temperature adjustment of the aerobic and anaerobic hydrogen chamber. The nano ceramic film roller is a hollow net shaped roller made of stainless steel material. An outer layer is plated with the nano ceramic membrane and a middle roller. An end of the aerobic preprocessing chamber is connected with an aeration device. The roller is plated with the nano ceramic membrane for micro nanometer aeration of thalli material and oxygen. An anaerobic hydrogen generating room is connected with a gas component analyzing system and a gas collecting device. A nano plating film (8) is covered on a cermet roller that is passed through a back washing aeration fermentation tank. The aerobic preprocessing chamber realizes anaerobic fermentation coupling and recycling of organic waste. An INDEPENDENT CLAIM is included for a method for producing hydrogen.
