Concentration threshold for polyethylene microplastics impacting nitrogen transfor-mation in heterotrophic nitrification-aerobic denitrification systems.
Heterotrophic nitrification-aerobic denitrification (HN-AD) enables simultaneous nitrification and denitrification under aerobic conditions. However, the pathways and mechanisms by which microplastics (MPs) affect HN-AD mediated nitrogen transformation remain unclear, limiting the development of remediation strategies...

Na2S Enhancement of Pyrrhotite/Sulfur Fixed Bed Reactors: Synergistic Denitrification Mechanism and Microbial Community Restructuring for Low-Alkalinity Advanced Nitrogen Removal
Advanced nitrogen removal from secondary effluent of municipal wastewater treatment plants (WWTPs) faces substantial technical challenges. This study investigated the denitrification performance and underlying mechanisms of a pyrrhotite/sulfur-coupled autotrophic denitrifying biological filter (PS-CFBR) enhanced by Na2...

Anammox-driven advanced nitrogen removal from high-strength ammonia wastewater: Multi-pathway synergism and microbiome spatial remodeling.
The anammox process demonstrates significant potential as an energy-efficient nitrogen removal technology in wastewater treatment. However, its operational strategies and nutrient transformation mechanisms for treating complex high-ammonia wastewater require further investigation. This study developed a continuous-flow...

Effects of Perfluorooctanoic Acid on River Sediment Denitrification and Remediation by Sulfur Autotrophic Denitrification–Anammox Coupled Microbial Consortia
This study explored the effects of perfluorooctanoic acid (PFOA) on river sediment denitrification and its remediation using a coupled sulfur autotrophic denitrifying‐Anammox microbial consortia. River sediments possessed intrinsic denitrification potential. However, PFOA did not inhibit ammonia nitrogen removal but ac...

Microbial transformation of a seaweed polysaccharide preparation enhances denitrification potential in low-carbon municipal tailwater.
Low-carbon secondary effluent presents significant challenges for effective nitrogen removal due to limited available organic carbon. In this study, a laboratory-scale microbial system integrating a polysaccharide-based external carbon source (MP) with the nitrate-assimilating bacterium Enterobacter hormaechei EN-1 was...

Performance and functional flora of simultaneous nitrogen removal, desulfurization and electricity generation in sulfide autotrophic denitrification-anammox-MFC coupled system.
In this study, a novel SAD-anammox-MFC coupled system was constructed for simultaneous nitrogen removal, desulfurization, and electricity generation. The optimal total nitrogen (TN) removal efficiency of 82.1% was achieved under the following conditions: a sludge inoculation ratio (SADB:AnAOB) of 1:2, external resistan...
