Pilot-scale implementation of mainstream anammox for municipal wastewater treatment against cold temperature

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Nov. 28, 2024

Applying anammox to municipal wastewater treatment promises enormous energy and resource savings; however, seasonally cold conditions pose a considerable challenge, impeding its future applications towards non-tropical regions. In this study, we establish pilot-scale plant (50 m3/d) in northern China implement the partial denitrification coupling process on actual wastewater. Despite seasonal cooling, nitrogen removal efficiency remains high, ranging from 75.0 ± 4.6% at 27.8–20.0 °C 70.4 4.5% 10–7.5 °C. This exhibits remarkable low-temperature tolerance, achieving an in-situ rate of 32.7 4.7 g-N/(m3·d) contributing up 39.7 6.7% removal. Further 15N stable isotope tracing kinetic tests reveal that is capable supplying increasingly abundant NO2- with decreasing temperature, enabling robust mainstream against cooling. From 27.8 7.5 °C, bacteria not only survive but thrive under conditions, absolute relative abundances increasing by 429.1% 343.5%, respectively. study sheds fresh light extending regions, taking necessary step forward toward sustainability goals sector. Low temperatures challenges applying sustainable technology Here, authors propose conduct evaluation, offering insights into colder locations.
