Abstract

a invenção refere-se a um método de tratamento de fluxo de efluente aquoso obtido durante a produção de furfural. a corrente de efluente aquoso contendo solventes orgânicos, furfural e água é submetida a destilação azeotrópica para obter uma corrente destilada e uma corrente de efluente tratada tendo valores mais baixos de dbo e dqo que podem ser ainda mais reduzidos por biometanização.
