Resumo: | Higher Education Institutions are providing technical, financial and human resources to deepen studies about sewage treatment, so as to contribute to this service to be extended to all Brazilian households. The University of Passo Fundo-UPF offers several undergraduate courses and Campus I receives about twenty-two thousand people including students, professors and employees, generating approximately 550 m³ / d wastewater, which are treated in the Wastewater Treatment Plant- ETE. The aim of this research was to analyze the performance of each installed equipment and the plant as a whole, to propose alternatives that are able to maximize the efficiency in removing pollutants. For eleven months, efluent sampled had been collecting at the entrance and the exit of the ETE and also of each equipment. The results indicate that the Campus I - UPF, produces an effluent with physicochemical and microbiological properties that are qualified as household sewage with heavy concentration and high concentration of surfactants and phosphorus substances, but low concentration of solids. Approximately 50% of the buildings in the Campus I, that generate wastewater, use septic tank and sink system, although 90% of them are connected to the sewer system installed. The study revealed that the Campus I produces an effluent with high variability in the concentration of the analyzed parameters. In the UASB reactor, 82% of the analysis showed removal of the organic load exceeding 70%. In the activated sludge system the performance did not show good enough in the phosphorus removal. In ETE, the variation of pH was between 6.8 to 7.76 and in three samples, the concentration of oil and grease resulted above 30 mg / L, maximum limit for disposal. The fecal samples resulted in superior values to the allowed limits. In eight samples, at the exit of the ETE, the concentration of surfactants were above the allowed limit. The study showed that in the UASB there is relation between the organic load applied and the efficiency and in the ETE the result was similar, but in the activated sludge system the same results were not observed. The temperature of the effluent inside of the equipment in the ETE ranged from 17 ° C to 27 ° C. The results suggest the alternative process of physico-chemical treatment complemented to the biological, in the phosphorus removal and installation at the exit of the ETE, the injector device of chlorine to disinfect the effluent and a antofoam feeder device to balance the concentration of tensoactive substances as well as deactivate the pre-treatment system with septic tank and sink and more rigor in the maintenance of grease traps installed in some buildings in the Campus |

A Universidade de Passo Fundo-UPF, oferece diversos cursos de graduação e o Campus I recebe cerca de vinte e duas mil pessoas entre alunos, professores e funcionários, gerando aproximadamente 550 m³/d de efluentes, que são tratados na Estação de Tratamento de Efluentes-ETE. O objetivo desta pesquisa foi analisar o desempenho de cada equipamento instalado e da estação como um todo, para propor alternativas que possam maximizar a eficiência na remoção dos agentes poluentes. Durante onze meses, foram efetuadas coletas de amostras de efluentes na entrada e na saída da ETE e de cada equipamento. Os resultados indicam que o Campus I da UPF, gera um efluente com características físico-químicas e microbiológicas que o classificam como esgoto doméstico com concentração forte e com elevadas concentrações de substâncias surfactantes e fósforo, mas baixas concentrações de sólidos. Aproximadamente 50% das edificações do Campus I, que geram efluentes, ainda utilizam o sistema tanque séptico e sumidouro, embora 90% delas estejam conectadas à rede coletora de esgotos instalada. O estudo revelou que o Campus I produz um efluente com elevada variabilidade nas concentrações dos parâmetros analisados. No reator UASB, 82% das análises apresentaram remoção da carga orgânica superior a 70%. No sistema de lodo ativado o desempenho não se mostrou satisfatório na remoção de fósforo. Na saída da ETE, em três coletas, as concentrações de óleos e graxas resultaram acima de 30 mg/L, limite máximo estabelecido para descarte. As amostras de coliformes na saída da ETE, resultaram valores superiores aos limites permitidos e em oito coletas, as concentrações de substâncias tensoativas ficaram acima do limite permitido. O estudo demonstrou que no UASB existe relação entre a carga orgânica aplicada e a eficiência. Na ETE o resultado foi semelhante, porém no sistema de lodo ativado o mesmo não foi verificado. A temperatura do efluente, no interior dos equipamentos da ETE variou entre 17 °C a 27 °C. Os resultados do estudo sugerem a alternativa de processo de tratamento físico-químico complementar ao biológico, na remoção do fósforo e a instalação, na saída da ETE, de aparelho dosador de cloro para a desinfecção do efluente e um aparelho dosador de antiespumante para equilibrar as concentrações de substâncias tensoativas, bem como desativar o sistema de pré tratamento com tanque séptico e sumidouro e maior rigor na manutenção das caixas de gordura instaladas em algumas edificações do CampusMade available in DSpace on 2018-01-10T17:55:50Z (GMT).
