Abstract in Portuguese
A presente pesquisa foi desenvolvida visando verificar a tratabilidade de afluentes de reatores anaeróbios através de filtros aeróbios. O sistema piloto estudado neste trabalho era composto de um Filtro Biológico Anaeróbio, existente na ETE piloto do Departamento de Hidráulica e Saneamento, modificado, para operar por meio aeração forçada, como Filtro Biológico Aeróbio. Neste trabalho apresentam-se os resultados obtidos na operação de filtro biológico aeróbio, utilizando-se três taxas de aplicação superficial, sem recirculação, para pós-tratamento de afluentes de esgoto sanitário de um reator anaeróbio compartimentado. A eficiência média em termos de remoção de DQO foi de 70% e DBOs 73%, para a taxa de aplicação hidráulica superficial de 1 ,5 m3 /m2 .dia; 55% de DQO e 59% de DBOs, para a taxa de 7,5-m3 /m2 .dia; e 40% de DQO e 48% de DBOs, para a taxa de 13 m3 /m2 .dia. No estudo comparativo, observou-se melhor correlação dos resultados obtidos ·em relaÇão à remoção de DBOs, · para os modelos de VELZ e ECKENFELDER.

Abstract in English
The pilot system studied in this work is an anaerobic filter existent in the pilot ETE of the Sanitation and Hydraulics Department, modified to operate by forced ventilation in a trickling filter. This work presents the results obtained in the operation of a trickling filter, using three superficial hydraulic rates with no recirculation for post-treatment of effluents of sanitary sewage from an anaerobic bassled reactor. The mean efficiency in terms of remova! of COD was: - 70% for a superficial hydraulic rate of 1,5 m3 /m2 .day; -55% for a superficial hydraulic rate of 7,5 m3 /m2 .day; -40% for a superficial hydraulic rate of 13 m3 /m2 .day. The mean efficiency in terrns of remova! of BOD5 was: - 73% for a superficial hydraulic rate of 1,5 m3 /m2 .day; -59% for a superficial hydraulic rate of 7,5 m3 /m2 .day; - 48% for a superficial hydraulic rate of 13 m3 /m2 .day. In a comparativa analysis, a better correlation of the results obtained was observed en relation to the removal of 8005, for VELZ and ECKENFELDER models.
