Sulfide- and nitrate-laden wastewaters at 2-35g/L NaCl were treated by DSR process. A C/N ratio of 3:1 was proposed to maintain high S0 conversion rate. The granular sludge with a compact structure and smooth outer surface was formed. The microbial communities of DSR consortium via high-throughput sequencing method suggested that salinity shifts the predominating heterotrophic denitrifiers at <10g/L NaCl to autotrophic denitrifiers at >10g/L NaCl.
