| 摘要 |
The invention relates to a process for photocatalytic purification of underground waters from sulphureted hydrogen and/or sulphides and may be used at the industrial enterprises and in household conditions. The process includes the flow aeration of water in the presence of dispersed in water particles of titanium dioxide and/or zinc oxide or activated coal, impregnated with polyvalent metal oxides, with fluidization of particles with oxygen-enriched air in constant magnetic field at the air consumption of 5...10 L per 1 g of sulphureted hydrogen and/or sulphides, during 3...5 min at the action of ultra-violet radiation with the wavelength of 180...380 nm and the intensity of 20...30 J/cm2?min.At the same time, as oxides of polyvalent metals are used the oxides of the type MenOm, where n=1 or 2; m=1, 2, 3 or 5; Me ? Ni; Co, Mo, V, Mn, Cu, Fe, Ti or Cr, at their concentration in the water of 3...5 g/dm3, and the concentration of the titanium dioxide particles constitutes 0,2...0,3 g/dm3, of the zinc oxide û 1,0...2,0 g/dm3.
