| Abstract: | In order to solve chromium waste water by means of electrolyzed deoxidation, we apply polyacrylonitrile carbon blanket as pole, graphite as bipolar plate, positive ion film as diaphragm, to an oxidation-reduction system, in which negative pole electrolyzes and reduces chromium waste water; meanwhile, oxides Fe~{2 } into Fe~{3 } in positive pole. Experimental result shows that the average electric current of battery system amounts to 92.29%, and chromium percentage remains less than 10~{-5} mol/L, which meets the national standard. |
