Feammox is a novel microbial process that enables simultaneous nitrogen and phosphorus removal in wastewater treatment. This study investigated the role of organic matter Feammox-driven nutrient during long-term bioreactor operation by gradually increasing influent chemical oxygen demand (COD) concentration from 0 to 50, then 100 mg/L. The results revealed ammonium efficiency was reduced 60.5 % 20.7 with COD In contrast, enhanced nitrate through heterotrophic denitrification, which outcompeted nitrate-dependent Fe(II) oxidation. Phosphorus increased up approximately 90 via Fe(II)-mediated precipitation, forming vivianite crystals, evidenced X-ray diffraction analysis. Continuous addition Fe(III) alleviated inhibitory effect on ammonia oxidation serving as an alternative electron acceptor, reducing competition. Therefore, optimizing levels ensuring sufficient availability are crucial for achieving efficient systems, particularly treating low carbon/nitrogen ratio.
