Abstract: Wastewaters are subjected to an oxidative treatment with a carbon-containing catalyst and an oxidizing agent by a process in which the carbon carrier used, e.g. graphite, coke or active carbon, is subjected to anodic oxidation in an aqueous mineral acid and then doped with molybdenum(Vl) and/or tungsten(VI) and/or vanadium(V) compounds.

Abstract: Oxidizable for organic and/or inorganic compounds in waters are subjected to catalytic degradation using a catalyst applied to an oxygen-storing inert carrier, for example of graphite, coke, a non-gassing coal or active carbon. The carrier used is coated with a cationic dye complexed with heteropolyacids and/or polyacids and/or salts or metal acids of subgroups V to VIII. The advantages of the process include the prevention of biological growth on the catalyst surface by the biocidal dye cation and the avoidance of calcium and magnesium deposits on the catalyst surface through the presence of the cationic solid.

Abstract: Anodic oxidn. of dye-contg. waste waters by electrolysis, opt. in presence of Cl' and/or SO4" ions, is effected in the presence of NO3', present in 0.1 - 20 (1-6) wt.% concn. w.r.t. dye-contg. waste water, esp. at pH 6. Pref. cathode consists of W and/or Mo opt. alloyed with 60 wt.% Fe and/or Ni, at least on surface facing the counter-electrode, and the anode of carbide-free alloys of Ti, Ta a and W, with 25 (18-22) wt.% Fe gp. elements, at least on surface facing the counter-electrode. The cell is cylindrical comprising an anode- or cathode core and a concentrically surrounding tubular cathode or anode, spaced by 10 (1-3) mm.

Abstract: In the catalytic breakdown of oxidisable organic and/or inorganic cpds. in water, with a supported catalyst, and oxidising agents, there is used an inert carrier, which has been coated with cationic dyes, coated with heteropolyacids and/or polyacids and/or metal salts or metal acids of Sub-gps. V-VIII.

Abstract: In a fuel cell which has an activated carbon-containing anode and an activated carbon-containing cathode and is preferably used for the oxidative treatment of waste waters containing oxygen or oxygen-containing compounds, the cathode has been subjected to partial anodic oxidation in a mineral acid at a potential epsilon h of from +1.3 to +10V and then doped with molybdenum(VI) and/or tungsten(VI) and/or vanadium(V) compounds, and the anode has been subjected to partial anodic oxidation in an aqueous mineral acid, cathodically reduced in an aqueous mineral acid and then impregnated with cobalt hydroxide and/or nickel hydroxide and/or copper hydroxide and/or zinc hydroxide, the anode and the cathode being separated by a porous polyelectrolyte through which the waste water flows.
