摘要: Abstract The feasibility of applying bio-augmentation tactics to remit the influence transient oxytetracycline (OTC) shock on anaerobic ammonium oxidation (ANAMMOX) process was evaluated. applied together with test, OTC concentration 518 mg L−1 and 1-h duration. 0.655–2.62 g volatile suspended solid (VSS) sludges were varied optimize dosage (BAD), appropriate time (BAT) determined. validity indicated by recovery performance sludge characteristics. restoring 38 h for bio-augmented reactor shorter than that non-bio-augmented (45 h), heme c content increased respectively from 0.195 ± 0.001, 0.267 ± 0.047, 0.301 ± 0.049, 0.340 ± 0.053 μmol g−1 VSS BAD 0.655, 1.31, 1.97, 2.62 g-VSS. results suggest enhances ANAMMOX following BAT are key operational factors.
