| Abstract: | The treatment of decentralized rural wastewater under sustained low-temperature conditions remains a significant challenge. This study evaluated a pilot-scale, multistage aerated biofilm (MAB) system equipped with hydrophilic polyurethane foam carriers during operation with influent temperatures dropping to 10.69 ± 0.77 °C. The system achieved robust performance, with NH (Copyright © 2026 Elsevier Inc. All rights reserved.) |
