The invention relates to a method for the treatment of waste water comprising an organic nutrient. According to the invention, the waste water is in a first step fed to sludge granules, after the supply of the waste water to be treated the sludge granules are fluidised in the presence of an oxygen-comprising gas, and in a third step, the sludge granules are allowed to settle in a settling step. This makes it possible to effectively remove not only organic nutrients but optionally also nitrogen compounds and phosphate.

L'invention se rapporte à un procédé de traitement d'eaux usées comprenant un élément nutritif organique. Selon l'invention, dans une première étape les eaux usées sont conduites dans des granules de boue qui, dans une deuxième étape, après le traitement des eaux usées, sont fluidisés en présence d'un gaz comprenant de l'oxygène puis, dans une troisième étape, les granules de boue peuvent être décantés dans une étape de décantation. Ce procédé permet d'extraire efficacement non seulement les éléments nutritifs organiques mais aussi éventuellement les composés azotés et les phosphates.
