Abstract

UN METODO PARA EL TRATAMIENTO DEL LODO DE AGUAS RESIDUALES QUE CONTIENE AL MENOS UN METAL QUE SE ORIGINA DE UN COAGULANTE DE TRATAMIENTO DE AGUAS RESIDUALES, Y FOSFORO Y METALES PASADOS PARA RECUPERAR DICHO METAL QUE HAY POR LO MENOS Y EL FOSFORO Y DESCARGAR DICHOS METALES PESADOS, EN DONDE DICHO METODO CONSISTE EN: ACIDIFICAR DICHO LODO DE AGUAS RESIDUALES PARA DISOLVER LOS METALES QUE SE ENCUENTRAN EN EL LODO; SOMETER EL LODO ACIDIFICADO DE AGUAS RESIDUALES A UNA EXTRACCION LIQUIDO-LIQUIDO PARA RECUPERAR AL MENOS UNA PORCION DE DICHO METAL QUE HAY POR LO MENOS; TRATAR EL REFINADO DE LA EXTRACCION EN UNA PRIMERA ETAPA DE PRECIPITACION CON LOS PRODUCTOS QUIMICOS ADECUADOS PARA PRECIPITAR METALES PESADOS, Y DESCARGAR DESPUES EL PRECIPITADO DEJANDO ASI UNA SOLUCION QUE TENGA UN CONTENIDO REDUCIDO DE METALES PESADOS; Y TRATAR LA SOLUCION QUE TIENE EL CONTENIDO REDUCIDO DE METALES PESADOS EN UNA SEGUNDA ETAPA DE PRECIPITACION CON LOS PRODUCTOS QUIMICOS ADECUADOS PARA PRECIPITAR EL FOSFORO Y RECUPERAR DESPUES EL FOSFORO PRECIPITADO.
