Further reducing total nitrogen (TN) and phosphorus (TP) in the secondary effluent needs to be realized effectively an eco-friendly manner. Herein, four pyrite/sawdust composite-based biofilters were established treat simulated for 304 days. The results demonstrated that TN TP concentrations from under optimal hydraulic retention time (HRT) of 3.5 h stable at <2.0 0.1 mg/L, respectively, no significant differences observed between inoculated sludge sources. had low N2O, CH4, CO2 emissions, effluent's DOM was mainly composed five fluorescence components. Moreover, mixotrophic denitrifiers (Thiothrix) sulfate-reducing bacteria (Desulfosporosinus) contributing microbial sulfur cycles enriched biofilm. Co-occurrence network analysis deciphered Chlorobaculum Desulfobacterales key genera, which formed obvious cycle process strengthened denitrification capacity. higher abundances genes encoding extracellular electron transport (EET) chains/mediators revealed pyrite not only functioned as conduit stimulate direct interspecies transfer by flagella but also facilitated EET-associated enzymes denitrification. This study comprehensively evaluates water–gas–biofilm phases during a long-term study, providing in-depth understanding boosted pyrite-based systems.
