saline wastewater is regarded as a challenge for wastewater treatment plants because high-salinity conditions negatively affect on traditional biological *** granular sludge(AGS)has gained attention as a promising technology for saline wastewater treatment because of its compact structure and the ability to withstand toxic ***,this study investigated the saltresistance performance,sludge properties and microbial community of AGS under low-salinity and high-salinity conditions,with the saline concentrations ranging from 0 to 50 g/*** results showed that AGS could withstand long-term saline stresses,and the maximum salinity reached 50 g/L within 113 *** salinities of 10,30,and 50 g/L,the chemical oxygen demand(COD)removal efficiencies were 90.3%,88.0%and 78.0%,*** also its maintained strength and aggregation at salinities of 10 and 30 g/*** of extracellular polymeric substances(EPS)by non-halophilic bacteria that enhanced sludge *** compact structure that ensured the microorganisms bioactivity helped to remove organic matters under salinities of 10 and 30 g/*** a salinity of 50 g/L,moderately halophilic bacteria,including Salinicola,Thioclava,Idiomarina and Albirhodobacter,prevailed in the *** dominant microbial communities shifted to moderately halophilic bacteria,which could maintain aerobic granular stabilization and remove organic matters under 50 g/L *** results in this study provide a further explanation for the long-term operation of AGS for treating saline wastewater at different *** is hoped that this work could bring some clues for the mystery of salt-resistance mechanisms.
