The present invention discloses a sludge anaerobic fermentation treatment method with simultaneously enhanced acid production and phosphorus removal. The method includes steps of: (1) adding waste activated sludge into an anaerobic reaction system, with a concentration of a total suspended solid (TSS) of 10000-15000 mg/L; (2) maintaining a pH value of the waste activated sludge at 10±0.1; adding powdery magnetite of 0.3-0.9 g/gVS S. Compared with simple alkaline conditions, in the method of the present invention, an accumulation amount of short chain fatty acids (SCFAs) in a fermentation broth is increased by 20%, and a content of orthophosphoric acid is reduced by 10%. The method can further improve the enhancing effect by using sulfuric acid to modify the magnetite, the accumulation amount of SCFAs can be increased by 36.7% at most, and the content of phosphorus and refractory organic substances can be reduced by 32.4% and 40.4% at most, respectively.

Sludge anaerobic fermentation treatment method with simultaneously enhanced acid production and phosphorus removal
