Abstract

Traitement de boues aqueuses renfermant des substances organiques, virus, bactéries et composés métalliques toxiques. Le procédé consiste à mélanger les boues avec de l'oxyde de calcium, ce qui conduit à une réaction exothermique dégageant de la vapeur d'eau. Le produit obtenu est solide, friable, sensiblement inodore et présente un pH d'au moins 12, ce qui désactive les bactéries et virus. Les composés toxiques métalliques (du plomb, de l'arsenic, etc.) sont rendus insolubles dans l'eau par l'augmentation de pH. L'invention concerne également le produit obtenu par ce procédé et un dispositif pour sa mise en oeuvre. Application du produit, une fois rendu compact, à la réalisation de remblais ou d'infrastructures de routes et, une fois neutralisé avec un acide, dans le domaine de l'agriculture.Treatment of aqueous sludge containing organic substances, viruses, bacteria and toxic metal compounds. The process consists of mixing the sludge with calcium oxide, which leads to an exothermic reaction releasing water vapor. The product obtained is solid, friable, substantially odorless and has a pH of at least 12, which deactivates bacteria and viruses. Toxic metallic compounds (lead, arsenic, etc.) are made insoluble in water by increasing pH. The invention also relates to the product obtained by this process and to a device for its implementation. Application of the product, once made compact, to the realization of embankments or road infrastructures and, once neutralized with an acid, in the field of agriculture.
