Zusammenfassung:The invention discloses a kitchen wastewater treatment method. The method comprises the following steps of: 1) adjusting the water quality and water quantity of kitchen wastewater, and carrying out primary coagulation, flocculation and precipitation; 2) adjusting the pH value of the solid-removed wastewater, and carrying out strong oxidation; 3) carrying out secondary flocculation on the oxidizedwastewater, and then feeding the wastewater into a sedimentation tank; 4) feeding precipitated effluent into an anaerobic hydrolysis reactor; 5) feeding anaerobic biochemical effluent into an anoxic reactor; 6) feeding the effluent of the anoxic reactor into an aerobic reactor; 7) after performing aerobic biochemical treatment, feeding effluent into a secondary anoxic biochemical tank; (8) enabling the effluent of a secondary anoxic reactor to enter an MBR and then enter a water outlet tank; and 9) flocculating and precipitating the wastewater in the water outlet tank again, and feeding the wastewater into an advanced
