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...
