Resumo: | This work was aimed at to perform the characterization qualitative and quantitative of the bacterial groups responsible for the oxidation and nitrogen reduction processes, applying the most likely number (NMP) technique in an experimental system consisting of UASB reactor, Percolator Biological Filter (FBP) and anoxic reactor, installed and monitored sequentially in the process of leachate treatment from landfill and domestic sewage. The efficiency of the ammonification stage observed during the conversion phase from organic to inorganic nitrogen in the UASB reactor was 6.4%, representing an increase of 9.8 mg/L of ammoniacal nitrogen in the effluent of the reactor. The NMP of ammonia oxidizing bacteria (AOB) ranged from 0,8x102 a 1,4x105 NMP/100ml. The NMP of nitrite oxidizers (NOB), varied from 0,8x102 a 2,2x104 NMP/100ml. For denitrifying bacteria, the NMP ranged from 7,0x103 a 2,6x104 NMP/100ml. The removal biological nitrogen ammoniacal observed in the FBP showed an average efficiency of 16.42%, generating an effluent with an average concentration of 136.4 mg NH4+.L-1 in the FBP. Based on these results, the system experimental demonstrated the ability to carry out global nitrogen transformation processes. However, the need for strict control over operational parameters is highlighted, in order to achieve greater efficiencies in nitrogen removal in the long run. |

La eficiencia de la etapa de amonificación observada durante la fase de conversión de nitrógeno orgánico a inorgánico en el reactor UASB fue del 6,4%, lo que representa un incremento de 9,8 mg/L de nitrógeno amoniacal en el efluente del reactor. La NMP de las bacterias oxidantes de amoniaco (BOA) osciló entre 0,8x102 y 1,4x105 NMP/100ml. La NMP de los oxidantes de nitrito (BON), varió de 0,8x102 a 2,2x104 NMP/100ml. Para las bacterias desnitrificantes, el NMP varió de 7,0x103 a 2,6x104 NMP/100ml. La remoción biológica de nitrógeno amoniacal observada en el FBP mostró una eficiencia promedio de 16,42%, generando un efluente con una concentración promedio de 136,4 mg NH4+.L-1 en el FBP. Con base en estos resultados, el sistema experimental demostró la capacidad de llevar a cabo procesos globales de transformación de nitrógeno. Sin embargo, se destaca la necesidad de un control estricto de los parámetros operativos, con el fin de lograr mayores eficiencias en la remoción de nitrógeno a largo plazo.Neste trabalho objetivou-se realizar a caracterização qualitativa e quantitativa dos grupos bacterianos responsáveis pelos processos de oxidação e redução de nitrogênio, aplicando-se a técnica do número mais provável (NMP) em um sistema experimental constituído por reator UASB, Filtro Biológico Percolador (FBP) e reator anóxico, instalados e monitorados de forma sequenciada no processo de tratamento de lixiviado de aterro sanitário e esgoto doméstico. A eficiência da etapa de amonificação constatada durante a etapa de conversão do nitrogênio orgânico a inorgânico, no reator UASB foi de 6,4%, representando um acréscimo de 9,8 mg/L de nitrogênio amoniacal no efluente do reator. O NMP das bactérias oxidantes de amônia (BOA) variou de 0,8x102 a 1,4x105 NMP/100ml. Já o NMP das Oxidantes de nitrito (BON), variou de 0,8x102 a 2,2x104 NMP/100ml. Para bactérias desnitrificantes, o NMP variou de 7,0x103 a 2,6x104 NMP/100ml. A remoção biológica de nitrogênio amoniacal observada no FBP, apresentou eficiência média de 16,42%, gerando um efluente com concentração média de 136,4 mg N-NH4+.L-1 no FBP. Com base nesses resultados, o sistema experimental demonstrou capacidade de realizar os processos globais de transformação do nitrogênio.
