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 bio...
