摘要

The method for oxidation anodic treatment of electrically conductive, natural water and/or aqueous solution for its disinfection by anodically generated ozone and/or for oxidatively decomposing of organic and/or inorganic components under use of an electrolysis cell divided as solid electrolyte by cation exchanging membrane suited for anodic ozone generation, where the electrolysis cell having anode plate made of conductive material coated with doped diamond, with perforated structure, comprises pressing the structure in a cell housing on cation exchanger membrane and porous cathode plate. The method for oxidation anodic treatment of electrically conductive, natural water and/or aqueous solution for the purpose of its disinfection by anodically generated ozone and/or for oxidatively decomposing of organic and/or inorganic components under use of an electrolysis cell divided as solid electrolyte by cation exchanging membrane suited for anodic ozone generation, where the electrolysis cell having an anode plate made of a conductive material coated with doped diamond, with a perforated structure, comprises pressing the structure in a cell housing on a cation exchanger membrane and a porous cathode plate that flows through by formed and/or supplied gas from top towards bottom. The anode plate has a strength of 0.5-3 mm, is disposed over a gap volume of 30-80% and is flowed in longitudinal direction of the aqueous solution to be treated with a flow velocity of 0.02-1.0 m/s, related to the gap volume of the anode plate. A diamond-coated expanded grid made of niobium is introduced as anode plate with perforated structure. The aqueous solution to be treated has an electrical conductivity of 10 mS/cm. The porous cathode consists of foam, knitted fabrics or nonwoven made of carbon, stainless steel or from nickel and/or its alloy. The aqueous solution to be treated is conveyed in circulation through the electrode plate. The anolyte circuit is flowed through in the sense of a reactor cascade one after another from the aqueous solution to be treated. The aqueous solution is conveyed without circulation guidance in unique conduit by the anode plate. Ozone formed in unique flow per gram is conveyed to 100% of the solution to be treated through the anode plate. A diluted acid (5) is dosed in the porous cathode plate in such a quantity in the existence of hardeners in the aqueous solution to be treated so that a weak acid with a pH-value of = 3 exists at lower discharge. An independent claim is included for an electrolysis cell for oxidation anodic treatment of electrically conductive, natural water and/or aqueous solution.
