NOVELTY - A pneumatic ultra-efficient anaerobic fermentation system comprises feedstock pipe (10), discharge pipe (12), U-type fermentation pipe (30), fermentation feedstock pipe side wall, discharge pipe wall set between U-type fermentation pipe at the top and feedstock discharge drain pipe, water feed pipe (20), water discharge pipe (22) connected horizontally with feedstock discharge drain pipe, gas-guide pipe (32) set in U-type fermentation pipe, inner pipe set between side wall of discharge pipe and side wall of plate feeding/discharge pipe side wall, and cloth bacteria device (50).    USE - A pneumatic ultra-efficient anaerobic fermentation system for promoting marsh liquid turbulence (claimed).    ADVANTAGE - The system does not need manual intervention and reduces operation difficulty.    DETAILED DESCRIPTION - A pneumatic ultra-efficient anaerobic fermentation system comprises feedstock pipe, discharge pipe, U-type fermentation pipe in which feedstock pipe and discharge pipe can be detachably inserted at 2 end side of U-type pipe, fermentation feedstock pipe side wall, discharge pipe wall set between U-type fermentation pipe at the top and feedstock discharge drain pipe, water feed pipe, water discharge pipe connected horizontally with feedstock discharge drain pipe, gas-guide pipe set in U-type fermentation pipe, and inner pipe set between side wall of discharge pipe and side wall of plate feeding/discharge pipe side wall. Each fermentation area is connected with independent and gas-guide pipe which has a valve. The system also includes cloth bacteria device consisting of drain pipe, U-type cloth bacteria pipe extending to each individual cell in the system, water pipe in one end side connected with water pressure (40), another end side connected with cloth bacteria pipe, discharging water pipe set with one-way valve which controls water pressure of biogas liquid in one-way flow into feedstock pipe, and control discharge pipe which controls biogas slurry flow into one-way check valve.
