| 摘 要： | 采用化学氧化还原-中和-絮凝沉淀法处理电镀废水中铬，研究了还原pH值、絮凝pH值、絮凝剂的用量、沉降时间对处理效果的影响。还原六价铬的最佳pH在2.0-2.2之间时，絮凝最佳pH值为9时，加入PAM，絮凝时间为0.5小时絮凝效果最好，处理后的Cr浓度最小。

| Abstract: | Study of removal of Chromium in electroplate wastewater by the method of oxidation - reduction - neutralization - flocculation - precipitation. The effect of pH during reduction, pH during flocculation, the amount of flocculant and sedimentation time on the treatment of Chromium ware studied. The optimal condition are： pH during reduction is 2.0-2.2, pH during flocculation is 9, sedimentation time is 0.5h. |
