Abstract

a invenção se refere a um processo para controlar a taxa de aeração durante a fase aeróbica de um processo de tratamento de efluentes, compreendendo: (a) medição, no momento t1, da concentração de amônio [nh4+]1 e concentração de óxido de nitrogênio [nox]1 em uma mistura de efluente e lodo microbiano que está sendo aerada; (b) determinação de uma concentração alvo de óxido de nitrogênio [nox]f1 no final da fase aeróbica com base, pelo menos, na atual concentração de amônio [nh4+]1 e na atual concentração de nox [nox]1; (c) determinação de um ponto de ajuste [nox]sp1 com base na interpolação entre [nox]1 e [nox]f1; (d) ajuste da taxa de aeração para minimizar o erro entre [nox]1 e [nox]sp1; e (e) repetição das etapas (a) a (d) em momentos adicionais ti. a invenção ainda se refere a um processo para o tratamento de efluentes, compreendendo (a) contato do efluente com lodo microbiano em uma zona de reator; (b) aeração da mistura de efluente e lodo; (c) controle da taxa de aeração de acordo com a presente invenção; e (d) separação de lodo do efluente tratado. por fim, a invenção se refere ao uso de monitoramento de concentrações de óxido de nitrogênio e amônio para controlar a taxa de aeração de uma fase aeróbica durante o tratamento de efluentes.
