Abstract

Procédé pour le traitement de liquides par épuration biologique aérobie, et dispositif pour la mise en oeuvre de ce procédé. Le liquide à traiter est d'abord soumis à un traitement primaire physico-chimique comportant une flottation. La boue en excès de l'épuration biologique est recyclée vers le traitement primaire, de sorte que la boue de flottation est le seul produit à évacuer. L'invention s'applique particulièrement à l'épuration des eaux résiduaires urbaines ou industriellesProcess for the treatment of liquids by aerobic biological purification, and device for carrying out this process. The liquid to be treated is first subjected to a primary physicochemical treatment comprising flotation. The excess sludge from the biological purification is recycled to the primary treatment, so that the flotation sludge is the only product to be removed. The invention is particularly applicable to the purification of urban or industrial wastewater.
