The invention discloses a method for recovering carbon source and nitrogen and phosphorus elements from surplus sludge and belongs to the field of sludge and sewage treatment, aiming at deficiencies that when the surplus sludge is fermented under alkaline environment in which sodium hydroxide is only used for providing alkalinity, the mole ratio of orthophosphate to ammonia nitrogen in fermentation liquor is low, which is disadvantageous to recovery of ammonia nitrogen and phosphorus in the fermentation liquor. In the invention, the pH value of the surplus sewage is controlled at alkaline condition by utilizing the characteristic that sodium phosphate can provide both alkalinity and orthophosphate combined with a sodium hydroxide solution, and organic matters in the surplus sewage are converted into organic acid to a maximum degree by enhancing the hydrolysis of the surplus sewage and restraining the methane production process. Furthermore, the dosage of sodium phosphate is controlled to adjust the mole ratio of orthophosphate and ammonia nitrogen in the surplus sewage fermentation liquor to be (0.9-1.4):1, thus being convenient for recovery of orthophosphate and ammonia nitrogen in the surplus sewage fermentation liquor in a struvite precipitate form. According to the invention, the acid production quantity of the surplus sewage by adopting the method is equal to that under alkaline environment in which sodium hydroxide is only used for providing alkalinity, and the cost is saved.
