Resumo: | Simultaneous nitrification and denitrification (SND) is a process that can remove both nitrogen and organic matter in a single unit. Several bench-scale studies show that the structured bed reactors (STBR) subjected to recirculation and intermittent aeration have achieved a good performance for SND treating different types of wastewater. Thus, this study took a step forward and evaluated the efficiency and stability of treating domestic sewage in a pilot-scale STBR. COD removal efficiencies higher than 87% were achieved in the whole experimental period. The highest Total-N removal efficiency was approximately 74 ± 7% by adopting a hydraulic retention time (HRT) of 47.2 h and intermittent aeration (2 h aerated and 1 h non-aerated). The setup of the aeration system was an important mechanism to ensure the optimal balance between nitrification and denitrification in a pilot-scale system. |

Varios estudios en escala de banco muestran que los reactores de lecho estructurado (STBR) con recirculación y aireación intermitente han logrado un buen desempeño para NDS, tratando diferentes tipos de aguas residuales. El propósito de este estudio fue evaluar la eficiencia y estabilidad del STBR a escala piloto tratando aguas residuales domésticas. Se lograron eficiencias de remoción de DQO superiores al 87% a lo largo del experimento. La mejor eficiencia de remoción de N-total fue aproximadamente 74 ± 7%, con un tiempo de retención hidráulica (HRT) de 47.2 h y aireación intermitente (2h airadas y 1 h no airada). La configuración del sistema de aireación fue un mecanismo importante para garantizar el equilibrio óptimo entre la nitrificación y la desnitrificación en un sistema a escala piloto.A remoção concomitante de matéria orgânica e nitrogênio em uma única unidade pode ser obtida a partir do processo de nitrificação e desnitrificação simultânea (SND). Diversos trabalhos em escala laboratorial mostram que os reatores de leito estruturado (STBR) submetidos à recirculação e aeração intermitente têm atingido desempenho satisfatório no tratamento de diversos tipos de águas residuárias, via processo SND. Desta forma, este trabalho teve como principal objetivo avaliar a eficiência e estabilidade do processo SND para o tratamento de esgoto doméstico em reator STBR em escala piloto. Eficiências de remoção de DQO superiores a 87% foram observadas ao longo de todo o período experimental. A máxima eficiência de remoção de N-total foi de, aproximadamente, 74 ± 7%, com tempo de detenção hidráulica (TDH) de 47.2 h e ciclo de aeração intermitente de 2h com aeração ligada e 1h sem aeração. A configuração do sistema de aeração se mostrou como um mecanismo fundamental para garantir o equilíbrio na ocorrência dos processos de nitrificação e desnitrificação na unidade piloto.Research, Society and Development2021-10-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2156010.33448/rsd-v10i13.21560Research, Society and Development; Vol. 10 No. 13; e589101321560Research, Society and Development; Vol. 10 Núm. 13; e589101321560Research, Society and Development; v. 10 n. 13; e5891013215602525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/21560/19259Copyright (c) 2021 Kiemi de Brito Murata; Bruno Garcia Silva; Carla Eloísa Diniz dos Santos; Dagoberto Yukio Okada; Rafael Brito de Moura; Eugenio Foresti; Márcia Helena Rissato Zamariolli Damianovichttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMurata, Kiemi de BritoSilva, Bruno Garcia Santos, Carla Eloísa Diniz dosOkada, Dagoberto YukioMoura, Rafael Brito deForesti, EugenioDamianovic, Márcia Helena Rissato Zamariolli 2021-11-21T18:26:28Zoai:ojs.pkp.sfu.ca:article/21560Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:57.242718Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
