Abstract

MELHORAMENTO DO PROCESSO DE REDUçãO DE DQO PARA OXIDAçãO ELETROQUìMICA. A presente invenção refere-se à descrição de um procedimento de tratamento da DQO de efluentes para oxidação anódica que combina a utilização de dois tipos diversos de ânodo com uma oportuna divisão proporcional da corrente. O primeiro tipo de ânodo é preferivelmente à base de diamente sintético dopado com boro, o segundo é um ânodo com tensões excedentes de oxigênio que preferivelmente contém óxidos de estanho e antimónio.
