Résumé
In low strength wastewater, aerobic granular sludge (AGS) with filamentous bacteria is often found and regarded as unstable AGS. However, in this study, a new view is proposed that AGS with filamentous bacteria (FAGS) may be the result of low strength wastewater selection. FAGS was found when AGS was cultivated for 30 days. By increasing the settling time, FAGS could keep the mixed liquid suspension (MLSS) at 0.89 g/L. FAGS showed excellent ammonia nitrogen removal performance. The ammonia nitrogen oxidation rate and denitrification rate of FAGS were 1.72 and 1.20 times higher than that of AGS, respectively. FAGS have large specific surface area (15.99 m
