Resumo: | The research aimed to treat sewage through combined anaerobic/aerobic system, using primary sludge and lysed excess sludge as an endogenous carbon source for removal of nutrients, aiming to produce effluent with low concentrations of organic material and nutrients and lower production excess sludge. The experiment was conducted in three phases. In the first, were performed respirometric tests as tool to assess the biodegradability of lysed biological sludge, through by techniques of cellular lysis induced: mechanical action, thermal and acid-base reaction. In the second phase, was monitored a Sequential Batch Reactor (SBR) together with Fermentation and Hydrolysis Reactor (FHR), which received excess sludge of SBR, tritured by mechanical action and primary sludge. SBR and FHR were operated with TRC of 3.36 and 10 days respectively. The third phase consisted of an anaerobic reactor followed by Immobilized Submerged with support Medium (polyurethane synthetic sponge) Aerated Reactor (ISMAR) operated in recirculation batch system. The results obtained from the respirometric tests found that the thermal sludge showed concentration biodegradable readily material greater than the tritured sludge and treated sludge by acid-base reaction. Values of the percentages of COD solubilized varied from 1.6% to 4.2%, with an average of 2.6%. The system presented promising results for the removal of nutrients, with removal efficiency of 85%, 93% and 98% for phosphorus soluble, nitrate and nitrite, respectively. However, the final effluent was maintained with concentration average of ammonia of 27 mgN-NH , considered out of the discharge standards. The combined system, anaerobic reactor and Immobilized Submerged with support Medium Aerobic Reactor (ISMAR), removed efficiently carbonaceous material (88%), TSS (86%), SSV (90%), TKN (94%) and N-NH4 - (96%). Producing effluent with average concentrations of nitrite and nitrate, respectively of 0.19 mgN-NO2-.L-1 and 2.52 mgN-NO3-.L. After addition of primary sludge the system, this presented a better performance with efficiency of COD removal gross and filtered 95%. However, the process of phosphorus removal was considered unsatisfactory since there was sludge disposal in the ISMAR reactor. Introducing an efficiency of removing just 20% for total phosphorus and 22% for the orthophosphate. |

O experimento foi realizado em três fases. Na primeira, foram realizados testes respirométricos como ferramenta para avaliar a biodegradabilidade de lodo biológico lisado, por meio de técnicas de lise celular induzida: ação mecânica, térmica e reação ácido-base. Na segunda fase, foi monitorado um Reator em Batelada Seqüencial (RBS) conjuntamente com Reator de Hidrólise e Fermentação (RHF), o qual recebia lodo de excesso do RBS, triturado por ação mecânica e lodo primário. O RBS e o RHF foram operados com TRC de 3,36 e 10 dias, respectivamente. A terceira fase foi constituída de reator anaeróbio seguido de reator aerado com meio suporte (esponja sintética de poliuretano) submerso imobilizado (RAMSI) operado em regime de bateladas com recirculação. Os resultados obtidos através dos testes respirométricos constataram que o lodo térmico apresentou concentração de material rapidamente biodegradável superior ao lodo triturado e ao lodo lisado por reação ácido-base. Os valores dos percentuais da DQO solubilizada variaram de 1,6% a 4,2%, com uma média de 2,6%. O sistema apresentou resultados promissores para a remoção de nutrientes, com eficiência de remoção de 85%, 93% e 98% para fósforo solúvel, nitrato e nitrito, respectivamente. Entretanto, o efluente final manteve-se com concentração média de nitrogênio amoniacal de 27 mgN-NH4.L-1, considerada fora dos padrões de lançamento. O sistema combinado, reator anaeróbio e reator aeróbio com meio suporte submerso imobilizado (RAMSI), removeram de forma eficiente material carbonáceo (88%), SST (86%), SSV (90%), NTK (94%) e N-NH4 -(96%). Produzindo efluente com concentrações médias de nitrito e nitrato, respectivamente de 0,19 mgN-NO e 2,52 mgN-NO3 -.L-1. Após a adição do lodo primário no sistema, este apresentou um melhor desempenho, com eficiência de remoção de DQO bruta e filtrada de 95%. No entanto, o processo de remoção de fósforo foi considerado insatisfatório, visto que não havia descarte de lodo no reator RAMSI. Apresentando uma eficiência de remoção de apenas 20% para o fósforo total e 22% para o ortofosfato.Made available in DSpace on 2015-09-25T12:18:51Z (GMT).
