Abstract

L'invention concerne un procédé combiné de traitement des boues impliquant d'une part un traitement par électro-osmose d'une boue permettant de déshydrater la boue, générant ainsi au moins un effluent, et d'autre part un traitement de cet effluent par électrocoagulation ou électroflottation. L'invention concerne également un procédé de traitement des effluents impliquant d'une part un traitement par électrocoagulation ou électroflottation d'un effluent, générant ainsi une boue à traiter et un effluent traité, et d'autre part un traitement de cette boue à traiter par électro-osmose de façon à la déshydrater. Les procédés de l'invention sont utiles afin de décontaminer des effluents et des boues. Ce procédés peuvent en outre permettre d'obtenir un niveau avancé de purification des boues et effluents traités.The invention relates to a combined sludge treatment process involving on the one hand an electro-osmosis treatment of a sludge making it possible to dehydrate the sludge, thus generating at least one effluent, and on the other hand a treatment of this effluent by electrocoagulation or electroflottation. The invention also relates to a process for treating effluents involving on the one hand a treatment by electrocoagulation or electroflottation of an effluent, thus generating a sludge to be treated and a treated effluent, and on the other hand a treatment of this sludge to be treated by electro-osmosis so as to dehydrate it. The methods of the invention are useful for decontaminating effluents and sludge. This process can also make it possible to obtain an advanced level of purification of the treated sludge and effluents.
