pH值对地下水除铁效果的影响

The Influence of pH Value on De-ferrous Effect of Groundwater

以理论探讨与实际工程相结合,研究pH值对地下水除铁工艺的影响;结果说明,在除铁工艺中,pH值的影响是不容忽视的。将Fe^(2+)转变成Fe^(3+)沉淀的pH值须大于5.5,保持很好的除铁效果和除铁速度pH值在中性范围内。pH值>7反应速度更快。

With the combination of theoretic discussion and realistic practice, the article studies theinfluence of pH value on groundwater de-ferrous process. The result shows that, in de-ferrous process, theinfluence of pH value can't be neglected. For transforming Fe～(2+) to Fe～(3+) sediment pH value must be bigger than5.5, then can get a satisfactory de-ferrous effect and keep the de-ferrous velocity in a neutral range. pHvalue bigger than 7 will result in a faster reaction velocity.
