Synergistic device for resource and energy recovery, pollution reduction and carbon reduction of kitchen waste

A synergistic device for resource and energy recovery, pollution reduction and carbon reduction of kitchen waste, comprising a pretreatment system, a centrifuge, a flocculation/flotation tank, an anaerobic fermentation tank, an anaerobic ammoniation system, an OAO (Oxic Anoxic Oxic) system and an electrocatalytic ozone synergistic treatment system which are communicated in sequence,

• wherein the pretreatment system is used for carrying out sorting, crushing, dewatering and solid-liquid separation of kitchen waste;
• the centrifuge is used for further separating liquid treated by the pretreatment system:
• the flocculation/flotation tank is used for removing suspended matters and microbubbles from the liquid treated by the centrifuge:
• the anaerobic fermentation tank is used for removing organic matters in the liquid:
• the anaerobic ammoniation system is used for removing ammonia nitrogen and total nitrogen in the liquid:
• the OAO system is used for removing COD (Chemical Oxygen Demand) in the liquid and carrying out denitrification and sludge-water separation;
• and the electrocatalytic ozone synergistic treatment system is used for rapidly degrading the organic matters in the liquid and removing the COD so as to enable waste water to reach a discharge standard.
