Conteúdo: |
The biogas produced in an UASB reactor treating domestic sewage was utilized for the evaluation of its effectiveness as alternative source of electron donor for denitrification. The experiment was carried out in a posttreatment unit consisting of a bench scale horizontal flow aerobic-anaerobic immobilized reactor fed with the UASB reactor effluent and supplied with air (for nitrification) and biogas (for denitrification) in separate modules aiming the removal of nitrogen. The experiment lasted five months. Complete denitrification was obtained and the results permit to afirm that H2S instead of CH4 was preferable used as electron donor. Although the reasons for this preference are not clear, some hypotheses are presented. More studies should be developed to provide a better understanding of the mechanisms involved in the use of H2S and elemental sulfur as electron donor for denitrification. The results obtained permit to consider the novel system configuration a promising reactor alternative for biological nitrogen removal and also for the treatment of the biogas produced in anaerobic reactors utilized for domestic sewage treatment. |
