Abstract

REFERIDO A UN PROCEDIMIENTO PARA TRATAR AGUAS RESIDUALES PARA ELIMINAR SIMULTANEAMENTE MATERIA ORGANICA, NITROGENO Y FOSFORO CON RECUPERACION DE ENERGIA EN FORMA DE METANO Y DIOXIDO DE CARBONO. DICHO PROCEDIMIENTO COMPRENDE DIRIGIR UNA CORRIENTE QUE CONTIENE AMONIACO A UN TANQUE DE PRETARATAMIENTO QUE PRODUCE LODO EN EXCESO, BIOGAS Y UNA CORRIENTE PRETRATADA. LA CORRIENTE PRETRATADA TIENE AL MENOS 45 % MENOS DE CARBONO QUE LA CORRIENTE QUE CONTIENE AMONIACO. LA CORRIENTE PRETRATADA SE DIRIGE ENTONCES HASTA UN TANQUE ANOXICO, QUE FOMENTA LA LIBERACION DE FOSFORO Y LA FERMENTACION DE MATERIA ORGANICA PARTICULADA Y DISUELTA. EL LIQUIDO MIXTO SE TRANSFIERE A UN TANQUE AIREADO QUE TIENE BAJAS CONCENTRACIONES DE OXIGENO DISUELTO PARA FOMENTAR EL DESARROLLO DE BACTERIAS DE LIBERACION DE FOSFORO QUE SE RECIRCULA EVENTUALMENTE AL TANQUE ANOXICO A MODO DE LODO ACTIVADO DE RETORNO. SE PRODUCEN LA NITRIFICACION, DESNITRIFICACION Y LIBERACION DE FOSFORO SIMULTANEAS EN EL TANQUE AIREADO. UN TANQUE DE MENBRANA SEPARA EL EFLUENTE TRATADO DEL LODO ACTIVADO QUE CONTIENE MICROORGANISMOS, EN EL UE UNA PRIMERA PARTE DEL LODO ACTIVADO SE RETORNA AL TANQUE ANOXICO COMO EL LODO ACTIVADO DE RETORNO
