Material or construction material or soil conditioner；
4) by step 1) in 50～80wt% of organic solid castoff add new organic solid into fermentation tank body 2
Garbage, is also back to the biogas residue of 20～30%VOL in fermentation tank body 2, and repeat step is 2) to step 3), complete one and do
The formula anaerobic fermentation cycle.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but this utility model is not limited to
The specific embodiment stated, above-mentioned specific embodiment be only it is schematic rather than restricted, this area it is common
Technical staff under enlightenment of the present utility model, without departing from this utility model objective and scope of the claimed protection situation
Under, many forms can be also made, these are belonged within protection of the present utility model.
