摘要：Salt concentration often fluctuates in influent industrial wastewater. The behavior of aerobic granular sludge (AGS) in response to the stress of alternating salt concentrations remains unclear. In this study, we ran six identical sequencing batch reactors to follow the performance and microbial characteristics of AGS under 1%, 2%, 4% salinity and corresponding alternating salinity, respectively. The results demonstrated that when compared with the control, alternating salinity not only increased the COD removal efficiency of the reactor significantly (p ? 2019 Elsevier Ltd
