  Background: Nitrogen and phosphorus are potential pollutants sources of water resources. They penetrate to the water resources through insufficient treated wastewater that is rich in nitrogen and phosphorus. The main aim of this paper is to evaluate the performance of fixed bed sequencing batch biofilm reactor in removing nitrogen and phosphorous from municipal wastewater. Methods: In this paper, we study the nitrogen and phosphorus removal from municipal wastewater applying biological method and using sequencing batch biofilm reactor with fixed bed in a volume of 30 liters. For this purpose, we run a pilot study including anaerobic and aerobic/anoxic reactors for duration of 12 months for the treatment of synthetic wastewater with 300, 500, 800, and 1000 mg/L inlet COD concentration, 15 mg/L phosphorus concentration, and 40 mg/L nitrogen concentration. Results: The minimum and maximum system efficiency for organic removal in terms of COD is 98.4 and 76.9%, nitrogen removal is 74.8 and 98.8%, and for the removal of phosphorus is 51.9 and 92.7%, respectively. Synthetic analysis shows significant match of the proposed system with Stover-Kincannon model and in most cases the correlation coefficient is reported 95%. Discussion:  FBSBR system shows considerable improvement in removing organic matter, nitrogen and phosphorus from municipal wastewater at low and high concentrations. Moreover, the obtained results from synthetic analysis show competitive matching with Stover-Kincannon model and it is suggested for using in optimization and design. Manuscript profile
