Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA SEPARACION DE METALES PESADOS A PARTIR DE MATERIALES CONTAMINADOS, EN PARTICULAR A PARTIR DE SUSTANCIAS SOLIDAS DISPERSAS, SUELOS, DESPERDICIOS ORGANICOS, LODOS ACTIVADOS DE CLARIFICACION O SIMILARES. DE ACUERDO CON LA INVENCION DEL PROCEDIMIENTO ABARCA LA SIGUIENTES ETAPAS: A) AFLUENCIA DE LA SUSTANCIA ORGANICA DESINTEGRABLE Y AGUA EN EL MATERIAL CONTAMINADO CON METALES PESADOS; B) MEZCLA DE LA SUSPENSION GENERADA BAJO CIERRE DE OXIGENO Y ELEVACION DE LA SOLUBILIDAD DEL METAL PESADO MEDIANTE DESCENSO DEL VALOR DE PH DE LA SUSPENSION POR MEDIO DE ACIDOS ORGANICOS FORMADOS BAJO CIERRE DE OXIGENO CON LA AYUDA DE MICROORGANISMOS A PARTIR DE LA SUSTANCIA ORGANICA Y PASO DEL METAL PESADO A UNA FASE ACUOSA; C) SEPARACION DEL MATERIAL LIBRE DE METAL PESADO PREDOMINANTE A PARTIR DE LA FASE ACUOSA QUE CONTIENE METAL PESADO; D) INTRODUCCION DE LA FASE ACUOSA QUE CONTIENE METAL PESADO EN UN REACTOR (20) DE BIOGAS; E) REDUCCION DE LA SOLUBILIDAD DEL METAL PESADO EN LA FASE ACUOSA MEDIANTE DESCOMPOSICION BIOLOGICA DE LOS ACIDOS ORGANICOS FORMADOS EN LA ETAPA B) DEL PROCEDIMIENTO BAJO EXCLUSION DE OXIGENO EN EL REACTOR (20) DE BIOGAS, CON LO CUAL SE FORMAN COMPUESTOS DE METAL PESADO DIFICILMENTE SOLUBLES; Y F) SEPARACION DE LOS COMPUESTOS DE METAL PESADO DIFICILMENTE SOLUBLES A PARTIR DE LA FASE ACUOSA YA LIBRE DE METALES PESADOS.
