Abstract
L'invention concerne un appareil (10) et un procédé pour éliminer le phosphore d'un débit d'effluents d'eaux usées (16) provenant d'un étang d'épuration d'effluents porcins. Le débit d'effluents d'eaux usées (16) est placé au fond d'un cristallisoir continu en forme de cône inversé (12) contenant un lit fluidisé de struvite. Une quantité efficace d'ammoniac (20) est introduite dans les effluents (16), au fond du cristallisoir (12), pour en augmenter le pH d'une valeur préétablie. Une quantité efficace de magnésium (18) est également introduite dans les effluents (16), au fond du cristallisoir (12). Les effluents d'eaux usées, dont la composition est rajustée, sont ensuite circulés en continu vers le haut, au travers du lit fluidisé de struvite, afin de réduire la teneur totale en phosphore des effluents (16) d'une quantité préétablie d'environ 80 % ou plus. Le débit d'effluents d'eaux usées traité (24) est retiré du sommet du cristallisoir (12), et les cristaux de struvite suffisamment grands pour s'enfoncer du fond du cristallisoir (12) sont périodiquement retirés du collecteur (22) situé sous le cristallisoir.
