Resumo: The anaerobic digestion efficiency varies according to several factors, such as: substrate carbon / nitrogen ratio, temperature, pH, alkalinity, and acidity. The main objective of this study was to describe the behavior of pH, alkalinity and total acidity of the affluent and effluent of a swine wastewater treatment system, in order to better understand the physicochemical process. The pH was measured immediately after collecting, and the methods of Jenkins et al. (1983) and Ripley et al. (1986) were used for quantifying the alkalinity, and the potentiometric method, for the acidity. The treatment system worked without large pH variation concerning the affluent and effluent of each unit, indicating good buffering conditions. The Ripley ratio (IA / PA) is characteristic for each effluent and dependent on the stage at which the reactor is working, and was determined as 1.96 for hydrolysis and acidification tank, 1.56 for reactors working on first stage (ABR), and 1.44 for reactors working on second stage (UASB).

Neste sentido, este trabalho teve por objetivo estudar e descrever o comportamento do pH, da alcalinidade e da acidez total do afluente e do efluente de um sistema de tratamento de efluente de suinocultura, para melhor compreensão do processo físico-químico. O pH foi medido imediatamente após a coleta. Os métodos propostos por Jenkins et al. (1983) e Ripley et al. (1986) foram utilizados para quantificar a alcalinidade e o método potenciométrico para quantificar a acidez. O sistema de tratamento operou sem grandes variações de pH do afluente e do efluente de cada unidade, demonstrando boas condições de tamponamento. Observou-se que a relação de Ripley (AI/AP) é característica para cada efluente e varia em função do estágio em que o reator está operando, determinando neste trabalho relação AI/AP igual a 1,96 para tanques de hidrolisação e acidificação, 1,56 para reatores que operam em primeiro estágio (RAC) e 1,44 para reatores que operam em segundo estágio (UASB).Universidade Estadual de Maringá2017-07-18T19:41:23Z2017-07-18T19:41:23Z2017-07-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPEREIRA, E.
