| description | The invention discloses a synchronous nitrogen and phosphorus removal method and device for low-carbon sewage, and belongs to the technical field of sewage treatment. Comprising the following steps: introducing a part of low-carbon sewage and residual sludge into a primary sludge fermentation reactor for anaerobic fermentation to obtain fermentation liquor; and introducing the fermentation liquor and the other part of low-carbon sewage into a nitrogen and phosphorus removal reactor for nitrogen and phosphorus removal treatment, and carrying out synchronous nitrogen and phosphorus removal on the low-carbon sewage in the nitrogen and phosphorus removal reactor. The method is applied to the aspect of synchronous nitrogen and phosphorus removal of low-carbon sewage, solves the problems of high production cost and poor nitrogen and phosphorus removal effect caused by a carbon source in the existing synchronous nitrogen and phosphorus removal process of low-carbon sewage, can effectively improve the utilization rat |
