The invention concerns a method and device for the continuous treatment of a flow of organic liquid sludge. Following the optional addition of granular mineral matter to the flow, the sludge (5) is injected at a rate q into a column of air which is at overpressure relative to atmospheric pressure, the air column circulating at a rate Q ] 5q in a chamber (2, 4) extending over a specific length L along a longitudinal axis (3), in order to create a fluidized bed, in which the sludge is aerolized, between air supply piping upstream of the sludge injection and an outlet reservoir or duct downstream of the resulting fluidized bed, the duct or reservoir being at atmospheric pressure or substantially at atmospheric pressure, and a flocculant (21) is introduced continuously downstream of the chamber into the fluidized bed in order to aggregate the organic matter before the solid part obtained in this way is separated from the liquid part, the resulting solid part thus being deodorized. |
