Abstract:
Nitrate (NO3-) poses a significant threat to water quality, emerging as a crucial pollution concern. Additionally, low C/N ratio wastewater faces challenges due to a shortage of carbon source. Autotrophic denitrification has garnered attention and research interest for its advantages, including no need for external carbon source, low cost and low sludge yield. In this review, we provide an overview of recent research progress in pyrite autotrophic denitrification processes and technologies for the systematically removal at NO3--containing wastewater system. The microbial characteristics in pyrite autotrophic denitrification are analyzed. In addition, the research progresses of the pyrite autotrophic denitrification technology are summarized, including multiple cooperative processes, potential and limitations. Ultimately, this review aims to offer novel insights and a theoretical foundation for achieving efficient wastewater treatment.
