Abstract
Este trabalho apresenta os resultados de estudo sobre o comportamento de um reator híbrido, operado em bateladas sequenciais, na remoção conjunta de matéria carbonácea, nitrogênio e fósforo de esgoto sanitário. Operado em ciclos de 8 horas de duração, o reator possuía em seu interior um suporte fixo com rede de nylon. Foram testadas cargas compreendidas entre 0,39 e 1,35 kgDQO.m-3.dia-1, 42 e 60 gN-NH4-.m-3.dia e 51 e 70 gP-PO4-.m-3.dia. O reator funcionou como um sistema estável e apresentou boas condições de depuração. A remoção da matéria carbonácea mostrou-se elevada, com eficiências médias de 92% de DBO5 e 80% de DQO. A remoção de nutrientes variou entre 59 e 71% para nitrogênio total e entre 45 e 67% para fósforo total. Tanto no lodo em suspensão, quanto no biofilme, foi observada a ocorrência de bactérias oxidadoras de amônio e micro-organismos responsáveis pela desnitrificação e remoção biológica de fósforo.
This paper presents the results about the behavior of a sequencing batch hybrid reactor on combined removal of carbonaceous matter, nitrogen and phosphorus from sewage. Operated in 8-hour cycles, the reactor had a nylon net fixed inside. Loads between 0.39 and 1.35 kg COD.m-3.day-1, 42 and 60 gN-NH4-m-3.day-1 and 51 and 70 gP-PO4-m-3.day-1 were tested. The reactor operated as a stable system and showed good depuration conditions. The carbonaceous matter removal was high, with 92 and 80% efficiencies average to BOD5 and COD, respectively. The nutrients removal varied between 59 and 71% for total nitrogen and between 45 and 67% for total phosphorus. In both, sludge in suspension and the biofilm, occurrence of ammonium-oxidizing bacteria and microorganisms responsible for denitrification and biological phosphorus removal was observed.
