Abstract

La présente invention concerne un dispositif pour traiter les boues d'épuration générées dans une station de traitement des eaux usées. Le dispositif de traitement des boues d'épuration comprend les éléments suivants: un cadre; un rouleau presseur installé dans le cadre; un rouleau d'entraînement installé dans le cadre et disposé au-dessous du rouleau presseur; un moteur d'entraînement pour fournir de l'énergie pour faire tourner le rouleau d'entraînement; une bande filtrante passant entre le rouleau presseur et le rouleau d'entraînement, celle-ci étant reliée au rouleau d'entraînement de manière à tourner dans le sens des aiguilles d'une montre ou dans le sens inverse des aiguilles d'une montre par rotation du rouleau d'entraînement; et un orifice d'alimentation en eaux usées à travers lequel les eaux usées peuvent être acheminées vers la bande filtrante, cet orifice étant installé au-dessus de la bande filtrante. Le rouleau presseur et le rouleau d'entraînement ont le même diamètre et tournent à la même vitesse.
