The invention discloses a method for recovering phosphate and extracting a product in a sewage and wastewater biological treatment system. Comprising the following steps: S1, measuring the concentration of P in sewage and wastewater to be treated; s2, Fe salt is added into the activated sludge biological reaction system for treating the sewage and the wastewater, FeII ions generated under the anaerobic environment condition react with phosphate ions in the sewage and the wastewater, and blue iron stone crystals are generated; and S3, taking out the blue iron stone-containing sludge from the bottom of the activated sludge system, uniformly mixing the blue iron stone-containing sludge with the heavy liquid in proportion, and centrifuging to obtain separated blue iron stone particles on the bottom layer. According to the method, under the neutral condition, the blue ferricite can be generated in situ in an activated sludge system for sewage treatment through the reaction of FeII ions and phosphate ...
