| Abstract: | The purpose of this study was to assess the swine wastewater treatment system, consisting of the anaerobic baffled reactor (ABR), followed by the upflow anaerobic sludge blanket (UASB) reactor at full scale. The system was monitored by analyzing samples collected in the influent and effluent of ABR and UASB. The following parameters were analyzed: temperature, pH, total suspended solids (TSS), volatile suspended solids (VSS), biochemical oxygen demand (BOD), and chemical oxygen demand (COD). Averages of total removal of COD and BOD were 96.7 and 98.4%, respectively. The mean concentrations of COD, BOD, TSS, and VSS at the final effluent were 611, 124, 138, and 134 mg L-1, respectively. The mean volumetric organic loadings (VOL) at the ABR and UASB were 10.29 and 0.99 kg COD m-1d-1. Therefore, the ABR-UASB system was found to be a promising alternative for the swine wastewater treatment |
| Abstract: | O objetivo deste trabalho foi avaliar o sistema de tratamento de águas residuárias de suinocultura, constituído de reator anaeróbio de chicanas (RAC), seguido por reator anaeróbio de manta de lodo (UASB), em escala real. O sistema foi monitorado por meio da análise de amostras coletadas nos afluentes e efluentes do RAC e UASB. Foram analisados os seguintes parâmetros: temperatura, pH, sólidos suspensos totais (SST), sólidos suspensos voláteis (SSV), demanda bioquímica de oxigênio (DBO) e demanda química de oxigênio (DQO). As médias de remoção total de DQO e de DBO foram 96,7 e 98,4%, respectivamente. As concentrações médias de DQO, DBO, SST e SSV no efluente final foram 611, 124, 138 e 134 mg.L-1, respectivamente. As cargas orgânicas volumétricas (COV) médias no RAC e UASB foram 10,29 e 0,99 kgDQO m kgDQO m-3d-1. Desta maneira, o sistema RAC-UASB apresenta-se como alternativa promissora para o tratamento de águas residuárias de suinocultura. |
