| 摘要 |
The present invention concerns a method for treating an ascending flow of an aqueous fluid by adsorption on activated carbon powder in a fluidised bed of activated carbon. The method comprises bringing the aqueous fluid to be treated into contact with a coagulation agent, a flocculation agent and fresh activated carbon powder, followed by injecting the aqueous fluid obtained from this first step into the lower part of a fluidised bed of activated carbon powder of which the average concentration of activated carbon varies from 2 to 10g/L. This step is followed by gravity separation of the aqueous fluid from the activated carbon powder particles, producing a cleaned and settled aqueous fluid. |
