Abstract

LA PRESENTE SOLICITUD ESTÁ DIRIGIDA A MÉTODOS PARA RETIRAR SULFURO DE UNA CORRIENTE DE AGUAS RESIDUALES. EL PH DE LA CORRIENTE DE AGUAS RESIDUALES SE AJUSTA PARA ESTAR ENTRE 7,0 Y 8,0. UN PRIMER AGENTE OXIDANTE SE MEZCLA CON LA CORRIENTE DE AGUAS RESIDUALES, OXIDANDO EL SULFURO EN AZUFRE ELEMENTAL. LA CORRIENTE DE AGUAS RESIDUALES LUEGO ES ABLANDADA MEZCLANDO CAL CON LA CORRIENTE DE AGUAS RESIDUALES. LA ADICIÓN DE CAL ADEMÁS ELEVA EL PH DE LA CORRIENTE DE AGUAS RESIDUALES A 10,0 O SUPERIOR, Y CONVIERTE EL AZUFRE ELEMENTAL EN SULFURO SOLUBLE (S2-) Y/O TIO–SULFATO SOLUBLE. EL CARBONATO DE CALCIO SE PRECIPITA Y EL SULFURO (S2-) Y/O TIO–SULFATO ES ADSORBIDO SOBRE ÉL. LUEGO DE ELLO, LA CORRIENTE DE AGUAS RESIDUALES SE DIRIGE A UN PROCESO DE SEPARACIÓN DE SÓLIDOS–LÍQUIDOS, LA CUAL SEPARA EL CARBONATO DE CALCIO Y EL SULFURO (S2-) Y/O TIO–SULFATO ABSORBIDOS DE LA CORRIENTE DE AGUAS RESIDUALES. EL SEPARADOR DE SÓLIDOS–LÍQUIDOS PRODUCE UN EFLUENTE QUE INCLUYE AZUFRE ELEMENTAL RESIDUAL. EL EFLUENTE LUEGO SE MEZCLA CON UN SEGUNDO AGENTE OXIDANTE, EL CUAL OXIDA EL AZUFRE ELEMENTAL RESIDUAL EN SULFATO, PRODUCIENDO UN EFLUENTE TRATADO.
