This study investigated the effect of gradual salt concentration increases on nitrogen removal performance from a sulfur-based autotrophic denitrification (SAD) process. A continuous operation reactor was used to adaptability denitrifying bacteria changes in salinity. The focused specifically effects SO42− and Cl− activity SAD bacteria. When 0∼4 ​g/L, NO3−-N removed at more than 97%. increased 15 decreased 51%.

Salinity stress results in ammonium and nitrite accumulation during the elemental sulfur-driven autotrophic denitrification process

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 14, 2024

In this study, we investigated the effects of salinity on elemental sulfur-driven autotrophic denitrification (SAD) efficiency, and microbial communities. The results revealed that when was ≤6 g/L, nitrate removal efficiency in SAD increased with increasing reaching 95.53% at 6 g/L salinity. Above salt concentration, performance gradually decreased, decreased to 33.63% 25 Approximately 5 mg/L hazardous nitrite detectable 15 salinity, but accompanied by generation ammonium. When ≥15 abundance salt-tolerant microorganisms, Thiobacillus Sulfurimonas , increased, while other species decreased. This study provides support for practical application saline wastewater.
