Abstract

Sulfur-mediated autotrophic biological nitrogen removal (BNR) processes favor the reduction of greenhouse gas (GHG) emissions compared to heterotrophic BNR processes. Micro-oxygen environments are widely prevalent in practical BNR systems, and the mechanisms of GHG emissions mediated by multi-elements, including nitrogen (N), sulfur (S), and oxygen (O), remain to be systematically summarized. This review reveals the functional microorganisms involved in sulfur-mediated BNR processes under micro-oxygen regulation, elucidating their metabolic mechanisms and interactions. The GHG abatement potential of sulfur-mediated BNR processes under micro-oxygen regulation is highlighted, along with recent advances in multi-scenario applications. The fate of GHG in wastewater treatment systems is explored and insights into future multi-scale GHG regulatory strategies are provided. Overall, the application of sulfur-mediated BNR processes under micro-oxygen regulation exhibits great potential. This review can act as a guide for the effective implementation of strategies to mitigate the environmental impacts of GHG emissions from wastewater treatment processes.
