| 摘 要： | 利用焦炭和铁屑在酸性含铬溶液中形成接触电池，使六价铬转化为三价铬，再在碱性液中把三价铬沉淀析出的方法，采用简单的设施对电镀厂含铬废水进行处理，以较少的投入达到国家废水排放标准。

| Abstract: | Cr(VI) is reduced to Cr(III) by contact batteries formed with coke and scrap iron in acid solution, then Cr(III) is deposited in alkaline solution. Using this theory, electroplating waste water can be treated to reach national discharge standards with less investment. |
