Solid carbon-driven biofilm system can provide sufficient carbon source for denitrification, while its counter-diffusional structure could inevitably induce the delayed carbon-nitrogen contact and electron transport, further affecting footprints mainly contributed by nitrous oxide (N2O) at wastewater treatment plants (WWTPs). However, detailed understanding of N2O dynamics during solid-phase denitrification (SPD) has not been disclosed. In this work, a fixed bed bioreactor driven polycaprolactone (PCL) was constructed operated over 180 days, achieving 97 %-99 % total nitrogen (TN) removal efficiency. Biochemical results indicated that under condition each (NO x ) concentration maintained 30 mg-N/L, competition between upstream downstream pools still observed PCL-driven even providing source. For example, coexistent nitrate (NO3 -)+ nitrite (NO2 -)+N2O condition, few electrons (i.e., 12.6 %) distributed to reductase (Nos), significantly decreasing reduction rate 1.42 mg/g VSS/h). Under TN in scheme containing NO3 -+NO2 -+N2O be 1.75-2.3 times higher than with sole NO mg-N/L. This suggested when treating multiple , only relatively improve efficiency, but also alleviate emissions. The abundance Bacteroidota Comamonadaceae ensured stable release conversion states.

Partial Nitritation/Anammox (PN/A) can achieve green, economical, and efficient biological nitrogen removal; however, the PN process contributes significantly to nitrous oxide (N2O, third most important greenhouse gas) emissions. Balancing stability of systems while reducing N2O emissions, particularly under varying salinity conditions, is a key challenge in applying PN/A for high-salinity high-ammonia wastewater treatment. This study explored long-term effects on performance emissions treating wastewater. The results showed that specific ammonia oxidation rates control two salinity-acclimated reactors were 78.84, 75.03, 42.60 mg N/(g VSS·h), indicating low (2.5 g NaCl/L) had minimal effect, high (10 inhibited ammonia-oxidating bacteria associated nitritation processes. Moreover, emission factors increased from 0.08 ± 0.04% 0.24 0.03% as rose 0 10 NaCl/L. Further analysis revealed stimulated production both aerobic anoxic stages. Particularly, by 2.84-11.14 times aerated stage 0.61-2.04 nonaerated (i.e. settling stages). Isotopic pathway indicated enhanced primarily stimulating nitrite reduction pathway. Additionally, mechanism investigation examined combined salinity-induced changes sludge properties microbial community These findings provide valuable insights treat high-strength understanding mechanisms
