Abstract

remoção simultânea anóxica de fósforo e nitrogênio. a presente invenção refere-se a métodos e sistemas que são fornecidos para o tratamento de água servida para remover simultaneamente nitrogênio, carbono e fósforo. o processo inclui um tanque anóxico que recebe pelo menos dois fluxos, incluindo águas servidas afluentes e lodo ativado de retorno. estes fluxos são misturados no tanque anóxico para promover a liberação de fermentação de particulado e matéria orgânica dissolvida. o licor misturado é transferido para um tanque aerado com baixas concentrações de oxigênio dissolvido para promover o desenvolvimento de bactérias de liberação de fósforo que é eventualmente reclicado para o tanque anóxico por meio do lodo de retorno ativado. nutrificação simultânea, desnitrificação, e a liberação de fósforo ocorrem no tanque aerado. um tanque de membrana separa o efluente tratado do lado ativado em um tanque de membrana.
