SEWAGE TREATMENT IN DOMESTIC REACTOR ANAEROBIC REACTOR OF HYBRID FOLLOWED WITH ALGAE IMMOBILISED

This study was performed aiming to evaluate the fecal contamination indicator and nutrient removals in immobilized algae reactor in post-treatment of anaerobic effluent. An Hybrid Anaerobic Reactor (HAR) fed with sewage was installed and its effluent post treated with Immobilized Algae Reactor (IAR). The RAI operated with moving-bed biofilm characteristics, and the support medium was polyurethane foam cut in cubes. The experiments were operated in three distinct phases at a greenhouse. The first one was characterized by a low insolation and temperature at a range from 22.4 to 30.2 ºC. At second phase ammonium sulfate was added to stimulate the nitrification. At the third phase the reactor was exposed to a greater insolation with temperature between 23.4 and 33.3ºC. The HAR provided an expressive organic matter and suspended solids removals, with 77 and 88% efficiency respectively. The IAR the N-NTK removal efficiency were respectively 96, 79 and 62% for the three phases. Nitrification occurred at first and second phases, at these phases the phosphorus removal was not efficient. On the other hand the third phase obtained a removal efficiency of 87% for orthophosphate and 99.98% for E. coli. The polyurethane was revealed as a good support medium for algae immobilization, being possible to efficiently remove the nutrients and the fecal contamination indicator organisms.Key Words: indicares faecal contamination, nutrients, reactor immobilized algae.

Nesse contexto foi instalado um Reator Anaeróbio Híbrido (RAH) alimentado com esgoto sanitário e o seu efluente foi pós- tratado em Reator com Algas Imobilizadas (RAI). O RAI operou com características de biofilme com leito móvel usando meio suporte de espuma de poliuretano cortada em cubos. O experimento foi instalado em uma casa de vegetação e operado em três fases distintas. A primeira caracterizada pela baixa insolação diária, temperatura variando 22.4 a 30.2 ºC. Na segunda fase foi adicionado sulfato de amônio que estimulou a nitrificação, na terceira fase o reator foi exposto a maior insolação com temperatura ambiente variando 23.4-33.3 ºC. O RAH proporcionou uma expressiva remoção de matéria orgânica e sólidos em suspensão, cuja eficiência foi de 77 e 88%, respectivamente. Com relação ao RAI a eficiência na remoção de N-NTK para as três fases foram respectivamente de 96, 79 e 62%, nas três fases. Na primeira e segunda fase ocorreu nitrificação. A remoção de fósforo mostrou-se pouco significativos na primeira e segunda fase, contudo na terceira fase, a eficiência foi em torno 87% de remoção para ortofosfato e 99.98% em relação a remoção de E. coli. O poliuretano mostrou-se um considerável meio suporte para imobilização de algas, sendo possível remover de forma eficiente os nutrientes e organismos indicadores de contaminação fecal.Palavras chaves: indicares de contaminação fecal, nutrientes, reator de algas imobilizadas.  Instituto de Ingeniería, Universidad Nacional Autónoma de México 2015-08-08 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículos evaluados por pares Artículos evaluados por pares Artículos evaluados por pares application/pdf https://www.revistas.unam.mx/index.php/aidis/article/view/51643 Revista AIDIS de Ingeniería y Ciencias Ambientales.
