(a–d) Nitrogen and P removals in the overlying water at different NH4Cl concentrations (C1: 3 mg/L; C2: 5 mg/L; C3: 7 mg/L; C4: 10 mg/L; C5: 15 mg/L). (a) Ammonium nitrogen removal efficiency. (b) Total nitrogen removal efficiency. (c) Nitrate nitrogen concentration in the overlying water. (d) Total phosphorus removal efficiency. Initial total phosphorus concentration was 1.0 mg/L. Bars sharing the same letters are not significantly different at P = 0.05. Values are mean ± SD (n = 3).
