Abstract

PROCEDIMIENTO Y DISPOSITIVO ASOCIADO PARA LA DEPURACION DE AGUAS RASICUALES, EN EL QUE LOS FANGOS EN SUSPENSION FORMADOS SON SOMETIDOS A DESGASIFICACION. PRIMERAMENTE, MEDIANTE MEDIOS (A), SE SOMETEN LAS AGUAS A PRETRATAMIENTO FISICO Y AJUSTE DEL PH. A TRAVES DEL CONDUCTO (6), LAS AGUAS PASAN A UNA INSTALACION DE POZO PROFUNDO (B), DONDE TIENE LUGAR LA PURIFICACION DE LAS MISMAS. EL FANGO FORMADO EN EL TRATAMIENTO PASA, POR CANAL (19), A UNA CELULA DE FLOTACION NATURAL (20) CON ARGOLLA (22 DE RETORNO DE FANGO RECUPERABLE. EL RESTO ES CONDUCIDO, POR CANAL (23), HACIE UN DEPOSITO (24), DESDE DONDE ES ELVADO HASTA UN DISTRIBUIDOR DE RIEGO (26), REGULABEL, SITUADO PRO ENCIMA DE UN LECHO DE GUARNICION (27) CONSTITUIDO POR UN APILAMIENTO DE MODULOS Y SEMBRADO DEMICROORGANISMOS. CADA MODULO ESTA FORMADO POR FINAS PLACAS PLANAS Y ONDULADAS. LOS FANGOS, YA DESGASIFICADOS, CAEN SOBRE UN RECIPIENTE (28), SALEN POR EL CNAL (29) Y ALIMENTAN UN DECANTADOR (30). PARTE DE LOS FANGOS SON RECICLADOS POR LA ARGOLLA (31) AL DISTRIBUIDOR (26).
