In the paper, some factors influencing the effect of reduction including the anodic material, the cathodal material, the area ratio of cathode to anode and the kind of electrolyte have been investigated and screened out. The result showed that under the same reduction conditions, the reduction of Cr6+ has better effect to use lead-antimony alloy as anode, iron plate as cathode, which area ratio is 7:1 and potassium sulphate as electrolyte.

本文首先对影响电解还原效果的阳极材料、阴极材料、阴阳极面积比和支持电解质加入的种类等因素进行了研究筛选，结果表明：在同样电解还原条件下，实验中阳极采用铅-锑合金，阴极采用铁板，阴阳极面积比取7∶1，支持电解质取为硫酸钾时，具有较好的Cr~(6+)还原效果；同时在采用铅-锑合金作阳极的条件下，通过正交实验，对影响直接在碱性介质中电解还原低浓度含铬废水的其他因素进行了研究，即研究了在电化学还原过程中，Cr~(6+)的初始浓度、极板间距、支持电解质的加入量、搅拌情况等因素对还原效果的影响程度，确定出了主要的影响因素。

To solve this problem we have done a lot of analysis tests, the use of solubilizer to increase the solubility of dye; dyeing process using soft water, and add the chelating agent to reduce the sodium sulphate caused by hardness, while improving, but you can not completely avoid the dyeing flowers and subsequently by a large number of trials found that there is a dye bath Fe3 +, Cu2 +, Zn2 +-induced dye accumulation of heavy metal ions such as lead-color flowers.

为解决此问题我们做了大量分析试验，使用增溶剂，增加染料的溶解度；染色过程中使用软水，并添加螯合剂来降低元明粉引起的硬度，虽有所改善，但不能彻底避免染花，后经大量的试验发现是染浴中存在Fe3+，Cu2+，Zn2+等重金属离子诱发染料聚集引起色花。
