PROCESS FOR LOWERING THE CONTENT OF ORGANIC MATERIALS AND NITROGEN PRODUCTS CONTAINED IN BROMIDE EFFLUENTS

摘要

P The invention relates to a process for lowering the content of organic matter and nitrogenous products contained in a brominated effluent liquid to solid which consists in subjecting said effluent to one or more physicochemical treatment chosen from: a) l acidification of a bromide aqueous solution or of a solution obtained by dissolving if the bromide effluent is solid followed by a vapor entrainment of the light organic compounds; b) the basification of the solution obtained in a) or well of the initial bromide aqueous solution obtained by dissolving if the bromide effluent is solid followed by a vapor entrainment of light amino organic compounds and / or NH3; c) the vapor entrainment of light organic compounds of the aqueous solution obtained in a), or of the solution obtained in b), or else of an initial bromide solution obtained by dissolution if the effluent is solid, without modification of pH; d) washing d a solid bromide effluent to be treated or a solid from the evaporation of a bromide aqueous solution resulting from one or more previous treatment (s), with an organic solvent, filtration of the suspension obtained, washing and drying of the cake obtained. /P
