A METHOD FOR PURIFYING FRESH, COMBINED AND SALINE WASTEWATER FROM RADIOACTIVE HEAVY METALS

摘要

The invention relates to environment management, particularly to methods for purifying a wastewater in order to climate a toxic impact of heavy and radioactive metals. A method for purifying fresh, combined and saline wastewater from radioactive and heavy metals using an electrolysis and a special active substance (sorbent), wherein the wastewater is fed to an electrolyzer with a chamber that is separated by a special membrane that is permeable for ions of metals separately of water, then changes of the pH occur in order to form complex compounds, which comprise ions of radioactive and heavy metals. Afterwards, the adsorption of the obtained compounds by the special active substance (sorbent) and filtering-off on a precoat filter that retains ions of heavy and radioactive metals are performed. The obtained filtrate is cemented without drying and evaporation in order to perform final deposition of the radioactive compounds.
