Abstract
A method and an apparatus for the purification of residual products from flue gas purification plants. Between a wet-desulphurization plant (1) for flue gas and an associated waste water-treatment plant (2) for the purification of the water used in the wet-desulphurization there is inserted a leaching apparatus (3, 7, 4) for the purification of hazardous residual products supplied through a conduit (6) from flue gas purification in dry-and and semidry-desulphurization plants by means of waste water supplied through a conduit (5) from the plant (1). The hazardous residual products supplied through the conduit (6) are admixed with the waste water supplied through the conduit (5) in a container (3) whereupon the mixture is conveyed to a filtration step (4) wherein the soluble salts and leachable heavy metals are separated from the filter cake produced and said filtrate being, through a conduit (8) conveyed to the waste water-treatment plant (2) whereas the leached out filter cake, now in the form of a waste dump-safe residual product, is conveyed to a deposit site through a conduit (9).
