Abstract

L'invention concerne une installation de traitement de boue qui peut pulvériser de l'eau contaminée de façon égale dans une boue contenant de l'eau qui a été déposée dans un concentrateur de boue. Cette installation de traitement de boue (1) comporte un mécanisme de récupération d'eau contaminée (4) qui comprend : un réservoir de récupération d'eau contaminée (3) pour récupérer de l'eau contaminée (6) résultant du nettoyage soit d'un concentrateur de boue (2) qui stocke de la boue contenant de l'eau (5) transportée à partir de l'installation de traitement des eaux d'égout par camion (8) ou tuyaux dans l'installation de traitement de boue (1) ; et un tuyau de retour d'eau contaminée (7) qui transporte l'eau du réservoir de récupération d'eau contaminée (3) au concentrateur de boue (2). La boue contenant de l'eau (5) qui est stockée dans le concentrateur de boue (2) est traitée par un procédé de fabrication de ciment (13). Une unité de pulvérisation d'eau (7a) sur le côté concentrateur de boue (2) du tuyau de retour d'eau contaminée (7) est disposée au-dessus de la position de chute pour la boue contenant de l'eau (5) dans le concentrateur de boue (2) à partir du camion (8) de telle sorte que l'eau contaminée (6) est pulvérisée sur le pic (5a) de la boue contenant de l'eau (5) qui a été collectée à l'intérieur du concentrateur de boue (2).
