摘要
通过研究在酸性条件下利用废铁屑处理剧毒的六价铬电镀废水的工艺条件 ,在最佳条件下废水中六价铬去除率达99 %以上 ,出水总铬含量为0.040mg/l,六价铬含量为0.002mg/l,大大低于国家排放标准0.500mg/l。
Under acidity condition, the process of using waste iron to remove toxic Chromium in waste water has been studied. Under the optimum condition, the efficiency of removing Cr6+ from waste water is beyond 99%, the total Chromium content of the discharged water is 0.040 mg/L, the Cr6+ content is 0.002 mg/L. They are far below the National discharge standard of 0.500 mg/l.
