Abstract
The invention relates to the protection of the environment. The invention may be most efficiently used for removing from aqueous media ions of heavy, non-ferrous and noble metals, organic substances, flotation reagents and petroleum products. The process comprises dissolving a metal anode in the presence of a non-soluble cathode and precipitating organic and inorganic impurities on the resultant compounds. The precipitation is conducted using a cathode made of a material having a potential which is higher than the potential of the anode, the electrodes being alternately brought in contact with the air oxygen and the liquor being treated. An apparatus for carrying out the process comprises a drum having openings for charging a metal scrap and the liquor being treated and for discharging the resultant precipitate. Wings are concentrically arranged on the inner surface of the drum. A perforated partition wall is provided adjacent to the outlet opening for preventing the loss of scrap from the drum. The metal scrap charged into the interior of the drum is used as the soluble anode and is in contact with the cathode. The cathode may be in the form of the inner surface of the drum lined with copper.
