Abstract

A invenção refere-se a um método para tratamento biológico de nitrogênio na forma de amônio em águas residuais por nitrificação em um reator biológico, compreendendo: pelo menos uma etapa a de aeração do reator biológico contendo a água residual a ser tratada, pelo menos uma etapa b de remoção de pelo menos uma porção dos nitritos produzidos na etapa a, e uma etapa c de extração, do reator, de uma fração do lodo resultando das etapas a e b. A invenção também se refere a um método para tratamento biológico de nitrogênio em águas residuais, por nitrificação/desnitrificação e/ou desamonificação, em que a nitrificação é implementada usando o método de nitrificação de acordo com a invenção.
