Iron sulfides-based autotrophic denitrification (IAD) is a promising technology for nitrate and phosphate removal from low C:N ratio wastewater due to its cost-effectiveness sludge production. However, the slow kinetics of IAD, compared other sulfur-based (SAD) processes, limits engineering application. This study constructed co-electron-donor (FeS S0 with volume 2:1) iron sulfur (ISAD) biofilter operated at as short 1 hr hydraulic retention time (HRT). Long-term operation results showed that superior total nitrogen removals ISAD were 90–100% 1–12 h HRT, highest rate up 960 mg/L/d. Considering sulfate production, HRT 3 could be optimal condition. Such performance in was achieved interactions between FeS S0, which accelerated process maintained acidity-alkalinity balance. Metagenomic analysis found enriched nitrate-dependent iron-oxidizing (NDFO) bacteria (Acinetobacter Acidovorax), sulfur-oxidizing (SOB), dissimilatory reduction ammonia (DNRA) likely supported stable reduction. The metabolic pathway completely DNRA, coupled oxidation, disproportionation, oxidation precipitation co-electron donors, responsible high-rate removal. provides potential highly efficient post-denitrification sheds light on balanced microbial S-N-Fe transformation.
