Abstract

Denitrifying sulfide removal (DSR) process comprising both heterotrophic and autotrophic denitrifiers can simultaneously convert nitrate, sulfide, and acetate into nitrogen gas, elemental sulfur (S⁰), and carbon dioxide, respectively. Sulfide- and nitrate-laden wastewaters at 2–35 g/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 <10 g/L NaCl to autotrophic denitrifiers at >10 g/L NaCl.
