Apparatus for treating metal containing waste waters

摘要

Method for treating metal containing waste water employing a vessel containing the waste water in which there is provided at least one anode and a cathode comprised of a plurality of electrically conductive elements and in which the waste water is subjected to electrolysis during which the cathode elements are being moved. The cathode elements are provided in the form of rods which are arranged in the vessel by means of at least two holding devices so that the rods extend parallel to one another and can be moved in the holding devices relative to one another. The holding devices are moved during the electrolysis process so that the rods strike one another again and again at spaced intervals. An apparatus is provided for practicing the method.
