Abstract: Disclosed is a method for recovering phosphorus from sludge rich in chemical phosphorus precipitates using a high-protein biomass waste, comprising introducing the sludge rich in chemical phosphorus precipitates into an anaerobic fermenter, adding a certain amount of a high-protein biomass by-product, sealing the fermenter and fermenting for 4-7 days. The method can effectively increase the phosphorus release efficiency from the sludge, and also generate volatile short-chain fatty acids and ammonia nitrogen in high concentrations. After dewatering, phosphorus and part of ammonia nitrogen can be recovered in a form of high-purity struvite crystals only by addition of a magnesium salt and adjustment of pH to 7.5-9.0. The volatile short-chain fatty acids can be used as an economical carbon source. The method allows simultaneous utilization of two solid wastes to recover carbon, nitrogen and phosphorus resources, and can reduce the usage of chemical reagents, saving the treatment cost.
