| 摘要 |
The invention relates to a method for treating an aqueous fluid, comprising bringing into contact the aqueous fluid with a fluidised bed of powdered activated carbon, and separating the aqueous fluid from the bed of powdered activated carbon, including a step of managing the fluidised bed of powdered activated carbon. The management step comprises the extraction of a fraction of the fluidised bed of powdered activated carbon in the form of sludge, at least a separation of the sludge extracted in the previous step so as to obtain a fraction having an insoluble index HC1 which is higher than that of the sludge before separation by at least 5 percentage points, and a reinjection of said fraction into the fluidised bed of powdered activated carbon. |
