Resumo: | Using two microscopy techniques, scanning electronic microscopy (SEM) and of epifluorescence, the present study analyzed the degeneration process caused by endogenia, especially under inanition situation. Two concentric UASB reactors, working in series and designed for pilot scale systems, treating wastewater from wet process of coffee fruits, were monitored as regard to the parameters physical, chemical and microbiological. The UASB reactors functioned in the field, and the atmospheric temperature oscillated from 16.5 to 38.8°C, and the affluent and effluent liquid temperature varied between 16.3 and 27.3°C, respectively. The initial data obtained for chemical oxygen demand (COD) were 1349 and 1173 mg L-1, and at the end of monitoring process the observed values for the same parameter were 120 and 102 mg L-1 for the reactor 1 and 2, respectively. The microscopy analysis applied to the solids profile of the reactors shown to be fundamental and must be applied as a quality parameter of the cultivated sludge, in order to observe its quality along the reactors profile mainly due to its decay. |

Dois reatores UASB concêntricos, funcionando em série, inseridos em um sistema-piloto de tratamento de águas residuárias do processamento dos frutos do cafeeiro por via úmida, foram monitorados quanto aos parâmetros físico-químicos e microbiológicos. Os reatores UASB operaram em campo, com oscilação de temperatura ambiente entre 16,5 e 38,8°C; as temperaturas do afluente e efluente dos reatores variaram de 16,3 a 27,3°C, respectivamente. Os dados iniciais obtidos para a demanda química de oxigênio (DQO) foram de 1.349 e 1.173 mg L-1, sendo, ao final do monitoramento atingido os valores de 120 e 102 mg L-1 para os reatores 1 e 2, respectivamente. Concluiu-se que a microscopia aplicada ao perfil de sólidos dos reatores é muito importante e deve ser empregada como parâmetro de qualificação do lodo cultivado em reatores UASB, especialmente quando do decaimento bacteriano.Universidade Estadual De Maringá2011-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionprocessos bioquimicos, constante de decaimento bacteriano, microbiologia da biomassaapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/829110.4025/actascitechnol.v33i2.8291Acta Scientiarum.
