【摘要】 为了电解还原处理含铬废水,以聚丙烯腈碳毡作电极,石墨板作双极板,以阳离子交换膜为隔膜,组装出氧化还原电池系统.此系统阴极电解还原处理含铬废水,同时阳极氧化Fe2+为Fe3+.电池系统的平均电流效率达92.29%,处理后废水中铬含量小于10-5mol/L,达到国家排放标准.更多还原

【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.更多还原
