Abstract

L'invention concerne un procédé de traitement d'eaux usées. Dans un mode de réalisation, on introduit des eaux usées brutes dans un contacteur biologique 22 comportant une série de disques 24 montés sur un arbre commun 25. On ajoute au courant d'eaux usées un adsorbant pouvant adsorber les impuretés du liquide. Cet adsorbant est par exemple du charbon activé que l'on ajoute en 26. L'addition de cet adsorbant améliore les caractéristiques de fonctionnement du contacteur biologique et on enlève les matières solides accumulées sur le contacteur à une vitesse équivalente à la vitesse à laquelle ces solides s'accumulent.The invention relates to a method for treating wastewater. In one embodiment, raw wastewater is introduced into a biological contactor 22 comprising a series of discs 24 mounted on a common shaft 25. An adsorbent capable of adsorbing impurities in the liquid is added to the wastewater stream. This adsorbent is for example activated carbon which is added at 26. The addition of this adsorbent improves the operating characteristics of the biological contactor and the solids accumulated on the contactor are removed at a speed equivalent to the speed at which these adsorbent. solids accumulate.
