Resumo: This work evaluates the process of nitrogen removal from wastewater at a meat processing plant, using nitrification and denitrification in bioreactors. The system was composed of two reactors with continuous flow operated in series: a hybrid reactor (anaerobic/anoxic) connected to an ascending flow biological filter with aeration, which recycled into the hybrid reactor. Feeding was accomplished with wastewater from the treatment station of a poultry and swine processing plant. The process was monitored by periodic analysis of the concentrations of ammonia, nitrate, nitrite, alkalinity, chemical oxygen demand (COD) and pH. The nitrogen removal efficiency of the system was compared with the maximum theoretical efficiency for the recycle rate used.

O sistema foi composto por dois reatores de fluxo contínuo operados em série: um reator híbrido (anaeróbio/anóxico) conectado a um reator tipo filtro biológico de fluxo ascendente com aeração, o qual possuía um reciclo para o reator híbrido. A alimentação foi realizada com água residuária proveniente da estação de tratamento de uma indústria processadora de aves e suínos. O acompanhamento do processo foi realizado por análises periódicas da concentração de amônia, nitrato, nitrito, alcalinidade, demanda química de oxigênio (DQO) e pH. A eficiência do sistema na remoção de nitrogênio foi comparada com a eficiência teórica máxima para a razão de reciclo utilizada.Universidade Estadual De Maringá2008-10-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/549510.4025/actascitechnol.v30i2.5495Acta Scientiarum.
