Process for treating effluents from waste incinerating installations and product obtained by this process.

摘要

Process for the treatment of effluents produced during the incineration of industrial and/or domestic waste, and the product originating from this process. According to the process the acidic gases present in the fumes (6) produced by the incineration of the waste are neutralised in a reactor (7) with an unsaturated basic solution, the gaseous heavy metals present in the fumes are condensed and adsorbed on solid particles entrained by the gaseous flow of the said fumes, and then these particles are filtered off and separated from the gaseous phase in a dust precipitator (9). These solid particles, consisting of the products of the neutralisation reactions of the acidic gases, of the excess reactant and of the fly ash, are then conveyed to a washing (10) or vitrification (13) plant. This process applies to the treatment of industrial and/or domestic waste and makes it possible to obtain a solid residue free from soluble pollutants and presenting no danger to the natural environment. <IMAGE>
