Abstract

"PROCESSO DE TRATAMENTO DE EFLUENTES AQUOSOS QUE CONTêM COMPOSTOS PEROXIDADOS". A presente invenção trata de um processo de purificação de efluentes aquosos que contêm em particular compostos peroxidados. Ela trata mais particularmente de um processo de purificação de efluentes aquosos que compreendem um processo de decomposição biológica anaeróbica dos compostos contidos nos efluentes. Os efluentes são tratados antes de sua decomposição biológica anaeróbica, em uma etapa de desperoxidação para diminuir a concentração de peróxido e evitar um efeito nocivo desses compostos sobre as enzimas ou bactérias.
