ABSTRACT:
The specification describes an oxidation and adsorption method for removing contaminating materials (pollutants) from aqueous liquids. The liquids are first subjected to an electrochemical treatment for the purpose of coagulation or agglomeration and partial oxidation by addition of NaOCl. Following this, using sedimentation and/or flotation, the agglomerated and coalesced sludge is removed from the liquid. In the liquid an excess of OCl.sup.- remains and this liquid, enriched in this manner, is supplied to adsorption columns, in which inorganic adsorption compositions are located having a high specific surface area so that a further oxidation is achieved by the excess OCl.sup.-, together with a partial adsorption and by addition of O.sub.3, complete oxidation is achieved. The organic contaminating materials are converted into CO.sub.2 products of adsorbing materials of different grain sizes and specific surface areas made of inorganic materials, following which the CO.sub.2 escapes from the liquid and is stored. The thus cleaned liquid then leaves the oxidation and adsorbing columns.
