Abstract
The object of the invention is to provide a method of treating wash water resulting from the scrubbing of process gases in smelting plants, according to which method the wash water is brought into intimate contact with the process gas and is circulated when the solids have been deposited. The method according to the invention draws off a partial flow from the wash water, mixes it with fresh water and uses it for rewashing the process gas. According to the invention, the wash water necessary for the scrubbers is drawn from a wash water container. In the sedimentation tank the insoluble portions are removed from the substance-charged wash water which is then introduced into the wash water container. The wash water required for the rewashing stage is removed from the wash water container and mixed with fresh water via the fresh water pipe. Solids are likewise removed in the sedimentation tank from the wash water from the rewashing stage, this wash water then being, circulated after introduction into the wash water container.
