Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA TRATAR AGUAS RESIDUALES UTILIZANDO UN PROCEDIMIENTO DE RETORNO DE SEDIMENTOS ACTIVADOS. EL SEDIMENTO PRIMARIOS SE SEPARA DE LA CORRIENTE DE AGUAS RESIDUALES Y SE LLEVA A UN TANQUE DE FERMENTACION Y SE DEJA SUFICIENTE TIEMPO PARA PERMITIR LA HIDROLISIS DE LOS SOLIDOS SUSPENDIDOS PARA PRODUCIR SUSTRATOS SOLUBLES. LOS SUSTRATOS DE RETORNO SE MEZ<CLAN CON EL SEDIMENTO ACTIVADO DE RETORNO Y SE SOMETEN A UN PERIODO DE TIEMPO SELECCIONADO PARA FORMAR SEDIMENTOS ACTIVADOS DE RETORNO ACONDICIONADOS. DESPUES, EL SEDIMENTO ACTIVADO DE RETORNO ACONDICIONADO SE MEZCLA CON AGUA RESIDUAL PRETRATADA EN UNA ZONA DE TRATAMIENTO AEROBICO INICIAL. DE ESTE MODO EL SEDIMENTO ACTIVADO DE RETORNO ACONDICIONADO MEZCLADO Y EL AGUA PRETRATADA SE LLEVAN A TRAVES DE UNA SERIE DE ZONAS DE TRATAMIENTO, QUE PUEDEN INCLUIR AL MENOS UNA ZONA DE TRATAMIENTO ANOXIDO, DONDE EL FOSFORO Y OTROSD CONTAMINANTES SE EXTRAEN DEL AGUA RESIDUAL
