Abstract

The invention relates to a device for decontamination of aqueous effluent, characterised in that said device includes a separator of immiscible liquid phases of the aqueous effluent to be treated connected with a unit for treatment by a germicidal and/or oxidising aqueous phase in order to reduce the COD (chemical oxygen demand) and/or the BOD (biological oxygen demand) of the separated aqueous effluent.
