Abstract

remoção biológica anóxica simultânea de fósforo e de nitrogênio com recuperação de energia. a presente invenção refere-se a métodos e a sistemas para tratar água servida para simultaneamente remover nitrogênio, carbono e fósforo, embora recuperando energia na forma de metano e dióxido de carbono. uma corrente contendo amônia é direcionada para um tanque de pré-tratamento que produz lodo em excesso, biogás e corrente pré-tratada. a corrente pré-tratada tem pelo menos 45% menos de carbono do que a corrente contendo amônia. a corrente pré-tratada é então direcionada para um tanque anóxico, que promove liberação de fósforo e a fermentação de matéria orgânica particulada e dissolvida. o liquor misturado é transferido para um tanque aerado tendo baixas concentrações de oxigênio dissolvido para promover o desenvolvimento de bactérias de fósforo que são eventualmente recicladas para o tanque anóxico por intermédio do retorno de lodo ativado. simultaneamente ocorre nitrificação, desnitrificação e liberação de fósforo no tanque aerado. um tanque de membrana separa o efluente tratado do lodo ativado em um tanque de membrana.
