DETAILED DESCRIPTION - A two-phase anaerobic fermentation device has a hydrolysis acidification reaction device, an aerobic fermentation device and an oxidation device, where the reaction device comprises two shunt-wound hydrolyzing acidifying basic hydrolysis acidification reaction pool and hydrolysis liquid collecting tank unit. A material accumulation tank is set with a liquid outlet hydrolysis acidification and biogas recycling inlet. A hydrolysis acidification liquid outlet is located on a bottom of a hydrolysis liquid gathering tank. An independent control valve is provided in an upper part of a basic unit. An anaerobic digestion reactor is provided with a feeding opening, a biogas output anaerobic digestion reactor and a slurry overflow port, where a filtering device is set on the anaerobic digestion reactor. A methane oxidation pond is connected to the anaerobic digestion reactor through a feed port of a feed pump. A liquid feeding hole is formed in an end of a slurry oxidation tank, and a liquid discharge hole is formed in another end of the oxidation tank. A liquid feeding liquid oxide opening is set behind a discharging hole in a baffle plate. The slurry oxidation tank is divided into three oxidation zones, where a micro-porous aeration is distributed at a bottom of each oxidation zone.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a two-phase anaerobic fermentation device.
