PROCESS FOR LOWERING THE CONTENT OFORGANIC MATTER AND NITROGENOUS PRODUCTS CONTAINED IN BROMIDE CONTAINING EFFLUENTS

摘要

The invention relates to a method of lowering the content of organic materials and in nitrogenous substances contained in a brominated liquid effluent to the solid, which consists in subjecting the said effluent to one or more treatment - chemical, physicochemical chosen from: a) the acidification of an aqueous solution brominated or of a solution obtained by dissolving, if the effluent bromide is solid with a vapor entrainment of the light organic compounds; b) the conversion of the solution obtained in a) or else of the aqueous solution initial brominated obtained by dissolving if the effluent bromide is solid with a vapor entrainment of the light organic compounds, amines and / or nh3; c) the drive to the vapour of the light organic compounds of the aqueous solution obtained in a), or else of the solution obtained at b), or else of a solution initial brominated obtained by dissolving if the effluent is solid, without any change of ph; d) the washing of an effluent bromide solid to be treated, or else of a solid from the evaporation of an aqueous solution brominated resulting from one or more treatment (s) above (s), with an organic solvent, filtration of the suspension obtained, washing and drying of the cake obtained.
