Pyrite is one kind of cost-effective electron donors for nitrate denitrification. In this study, a pyrite-driven autotrophic denitrification biofilter was applied for simultaneous removal of NH4+ and NO3- over the 150-day. The influent NH4+/NO3- ratio (0.3-1.7) had less effect on system performance, while for the hydraulic retention times (HRTs, 24-3 h), the removal percentage of both 90% and removal loading rates of 52.8 and 59.4 mg N/(L·d) for NH4+ and NO3- removal were obtained at the HRT of 6 h.
