| 摘要 |
The objet of the invention is a method and device for purifying aqueous solutions or the like, where the component to be removed, for example in a dissolved or solid state, is converted to the solid phase, the said method including the addition of coagulating and flocculating agents; the separation of larger solid particles from the suspension thus obtained by settling; and the removal of the remaining components from the suspension by electroflotation. The invention is intented especially for purifying water and technical solutions of different types of dissolved and solid substances. In the method, electroflotation is used to remove the remaining components by saturating the suspension with the gas released in the electrolysis in connection with turbulence and by removing the foam in laminar conditions. In the electroflotation device (10) the chamber (30) consists of a gas saturation chamber (12) in which is mounted an electrode unit (13) for saturating the suspension with the gas released in the electrolysis, and of a flotation compartment (15), in which is mounted an electrode unit (18) for foaming. |
