Resumo: | Since hog raising concentrates a huge amount of swine manure in small areas, it is considered by the environmental government organizations to be one of the most potentially pollutant activities. Therefore the main objective of this research was to evaluate by operational criteria and removal efficiency, the performance of a Anaerobic Baffled Reactor (ABR), working as a biological pre-treatment of swine culture effluents. The physical-chemical analyses carried out were: total COD, BOD5, total solids (TS), fix (TFS) and volatiles (TVS), temperature, pH, total Kjeldahl nitrogen, phosphorus, total acidity and alkalinity. The ABR unit worked with an average efficiency of 65.2 and 76.2%, respectively, concerning total COD and BOD5, with a hydraulic retention time (HRT) about 15 hours. The results for volumetric organic loading rate (VOLR), organic loading rate (OLR) and hydraulic loading rate (HLR) were: 4.46 kg BOD m-3 day-1; 1.81 kg BOD5 kg TVS-1 day-1 and 1.57 m3 m-3 day-1, respectively. The average efficiency of the whole treatment system for total COD and BOD5 removal were 66.5 and 77.8%, showing an adequate performance in removing the organic matter from swine wastewater. |

Nesta pesquisa objetivou-se, por conseguinte, avaliar a utilização de um reator anaeróbio compartimentado (RAC), como unidade de pré- tratamento de um reator tipo UASB, em escala piloto, na adequação ambiental dos efluentes de suinocultura, avaliando critérios operacionais e a eficiência. As análises físico-químicas realizadas foram: DQOtotal, DBO5, sólidos totais (ST), fixos (SF) e voláteis (SV), temperatura, pH, nitrogênio total Kjeldahl, fósforo, acidez total e alcalinidade. A unidade RAC trabalhou com eficiência de 65,2 e 76,2% para a remoção de DQOtotal e DBO5, respectivamente, para o TDH médio de 15h. Os valores obtidos para a carga orgânica volumétrica (COV), carga orgânica biológica (COB) e carga hidráulica (CH) foram de 4,46 kgDBO5 m-3 dia-1; 1,81 kg DBO5 kg SVT-1 dia-1 e 1,57 m3 m-3 dia-1, respectivamente. O sistema de tratamento proporcionou eficiências médias de remoção de 66,5 e 77,8% para DQOtotal e DBO5, respectivamente, demonstrando adequada performance na remoção de material orgânico proveniente do efluente líquido da suinocultura.Universidade Estadual de Maringá2017-08-14T16:40:36Z2017-08-14T16:40:36Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPEREIRA, E.
