NOVELTY - Bean product waste treatment process comprises carrying out hydrolysis of particulate matter and soluble macromolecule substance and chemical oxygen demand (COD) degradation; sending into anaerobic tank to generate methane, degrading COD, carrying out synchronous degradation of COD and nitrogen (N); synchronization liquid part degradation tank end returning to inlet end to mud-water separating device, discharging mud-water after separating clean water and returning sludge to hydrolysis acidification pool; and discharging residual sludge into sludge treatment system.    USE - Bean product waste treatment process.    ADVANTAGE - The treated water reaches integrated wastewater discharge standard GB8978-1996 first level discharge standard.    DETAILED DESCRIPTION - Bean product waste treatment process comprises:    (A) introducing wastewater to hydrolysis acidification pool through adjusting pool, carrying out hydrolysis of particulate matter and soluble macromolecule substance and COD degradation;    (B) sending into anaerobic tank to generate methane, degrading COD, flowing into biological synchronous degradation pool, carrying out synchronous degradation of COD and N;    (C) returning synchronization liquid part degradation tank end to inlet end of mud-water separating device, discharging mud-water after separating clean water and returning sludge to hydrolysis acidification pool; and    (D) discharging residual sludge into sludge treatment system.    An INDEPENDENT CLAIM is included for waste treatment device comprising wastewater adjusting pool (1), hydrolysis acidification pool (2), anaerobic pool (3), biological synchronous degradation tank (4) and mud-water separating device (6).
