Abstract

EN UN PROCESO DE DEPURACION DE AGUAS RESIDUALES SULFATADAS SE HACEN REACCIONAR LAS AGUAS RESIDUALES CON PH DE 1 A 6 EN UNA ZONA DE MEZCLA CON UNA SOLUCION DE CLORURO CALCICO DE FORMA QUE EN LA ZONA DE MEZCLA SE AJUSTE LA PROPORCION MOLAR DE CA++ A SO4++ DE (0,5 A 3) : 1. LA BAJADA DE LA ZONA DE MEZCLA SE INTRODUCE EN UNA ZONA DE TRATAMIENTO REMOVIDA, MIENTRAS QUE EL REBOSE DE LA ZONA DE TRATAMIENTO SE TRASPASA A UNA ZONA DE ESPESAMIENTO, DE LA QUE SE LLEVA EL LODO DE ESPESADO A UNA ZONA DE FILTRADO. UNA INSTALACION PARA EJECUTAR ESTE PROCESO CONSTA DE UN DISPOSITIVO DE NEUTRALIZACION, EL CUAL CONSTA DE UN RECIPIENTE DE NEUTRALIZACION, UN CRISTALIZADOR Y UN RECIPIENTE DE SEDIMENTACION. SIMULTANEAMENTE, ESTA CONECTADO UN TUBO CONDUCTOR DE AGUAS RESIDUALES (1) CON UN SEGMENTO DE MEZCLA (2) EN EL QUE DESMBOCA TANGENCIALMENTE UNA CONDUCCION (3) PARA UNA SOLUCION DE CALCIO IONOGENICO. EL SEGMENTO DE MEZCLA (2) ESTA CONECTADO CON LA ZONA INFERIOR DE AL MENOS UN RECIPIENTE DE TRATAMIENTO (5) EN EL SENTIDO DE LA CORRIENTE. EL RECIPIENTE DE TRATAMIENTO (5) ESTA UNIDO SEGUN LA CORRIENTE A UN ESPESADOR (12), DE CUYO DESAGUE SALE UNA CONDUCCION DE LODO (13) HACIA IN DISPOSITIVO DE FILTRACION. FINALMENTE, ESTA PREVISTA UNA CONDUCCION (14) DE LA ZONA SUPERIOR DEL ESPESADOR (12) AL RECIPIENTE DEL DISPOSITIVO DE NEUTRALIZACION.
