Abstract The effects of NaHCO₃ dosage on the nitrogen removal efficiency of the waste iron scraps-assisted anammox systems were investigated. The results show that, with a decrease in NaHCO₃ dosage gradually from 250 to 125mg/L, the TN removal efficiency and sludge specific anammox activity of the conventional anammox system (R1) reduced to below 65% and by 16%, respectively. In contrast, the TN removal efficiency of the waste iron scraps (WIS)-assisted anammox systems (R2 and R3) increased to 76.9%~82.2%, while the sludge specific anammox activities of R2 and R3 were 39.5%~51.4% higher than that of R1. The decrease in the NaHCO₃ dosage also led to an increase in the ΔNO₃^--N/ΔNH₄⁺-N ratio of R1 (to 0.34). However, the ΔNO₃^--N/ΔNH₄⁺-N ratio of both R2 and R3 was 0.20~0.21. The inorganic carbon limitation (rather than pH or alkalinity) was the main reason for the deterioration of nitrogen removal efficiency of R1. The WIS-assisted anammox systems could effectively deal with the adverse effects of the inorganic carbon limitation and enhance the nitrogen removal efficiency. Moreover, the direct coupling system of iron scrap and anammox (R2) possessed a higher nitrogen removal efficiency, sludge specific anammox activity and NO₃^--N reduction ability than that of the indirect coupling system (R3) under the conditions of inorganic carbon limitation (IC/TN=0.04).
