Abstract

Un procédé de traitement chimique de cendres de boues d'épuration consiste à dissoudre (S10) un matériau de départ, provenant de cendres de boues d'épuration, dans un acide comprenant de l'acide chlorhydrique. Le matériau de départ comprend au moins des composés de silicium et de fer. Les résidus non dissous sont séparés (S12), laissant un lixiviat. La quantité de silice colloïdale dans les cendres de boues d'épuration dissoutes est régulée (S15). Le fer et/ou le phosphore sont extraits (20) du lixiviat par extraction liquide-liquide à l'aide d'un solvant organique. Au moins une partie d'un raffinat au moins partiellement appauvri en fer et/ou en phosphore provenant de l'étape d'extraction du fer et/ou du phosphore est remise en circulation (S90) pour dissoudre le matériau de départ, provenant de cendres de boues d'épuration. La partie remise en circulation du raffinat, au moins partiellement appauvrie en fer et/ou en phosphore, comprend des ions chlorure. Est également divulgué un agencement pour le traitement chimique de cendres de boues d'épuration.
