Abstract

PROCEDIMIENTO DE TRATAMIENTO DE AGUAS, POR LODOS ACTIVADOS, QUE COMPRENDE, UN PROCESO DE OXIDACION DE CONTAMINACIONES CARBONADAS Y UN PROCESO DE NITRIFICACION, EVENTUALMENTE ASOCIADO A UN PROCESO DE DESNITRIFICACION Y/O DE DESFOSFATACION. ESTE PROCEDIMIENTO COMPRENDE UNA ETAPA REACCIONAL A LO LARGO DE LA CUAL TIENEN LUGAR REACCIONES DE DESCONTAMINACION; UNA ETAPA DE CONCENTRACION DE LOS LODOS; UNA ETAPA DE GENERACION EN LA QUE SE FORMA LA EDAD DE LOS LODOS Y/O UNA ETAPA DE INICIACION DE REACCIONES QUE SE DESARROLLAN A LO LARGO DE LA ETAPA REACCIONAL. ESTACION DE DEPURACION DE AGUAS QUE COMPRENDE UNA FUENTE PARA EL DESARROLLO DE OPERACIONES DE DEPOLUCION (1), UNA FUENTE PARA LA FORMACION DE LA EDAD DE LO LODOS Y/O LA INICIACION DE REACCIONES DE DESCONTAMINACION (4) Y UN APARATO DE CONCENTRACION DE LODOS MONTADO EN BUCLE (3). APLICACION A LA DEPURACION BIOLOGICA DE AGUAS RESIDUALES.
