The invention discloses a device and a method for synchronously recovering organic matters, nitrogen and phosphorus from urban sewage, and belongs to the technical field of sewage treatment. The device comprises a water inlet tank, a first FO membrane, an anaerobic acid production reactor, a second FO membrane and a nitrogen and phosphorus recovery device, the first FO membrane is connected with the water inlet tank to form a circulation loop, and the anaerobic acid production reactor is connected with the water inlet tank; a micro-filtration membrane is arranged in the anaerobic acid production reactor and is connected with a water outlet tank, and the second FO membrane is connected with the water outlet tank to form a circulation loop. The FO membrane is used for concentrating urban sewage, the subsequent sewage treatment capacity is reduced, meanwhile, the concentration of organic matter and nitrogen and phosphorus in the sewage is increased, the anaerobic acid production reactor is used for conducting an
