摘要：

就零价铁处理含铀废水进行了试验研究, 考察了pH、震荡时间、静止时间、铁的投加量等因素对铀去除率的影响, 得到了最佳实验条件。通过试验对比了铁粉和废铁屑对铀废水的处理效果, 发现废铁屑比铁粉对铀的去除率更高。最后分析探讨了铁粉和废铁屑对废水中铀的去除机理, 指出零价铁对废水中铀的去除符合Langmuir吸附规律。

Abstract:

The treatment of uranium-containing wastewater by using non-valent iron has been studied. The effects of pH, iron dosage, shaking time and still time on the removal rate of uranium are investigated, and the optimum experiment conditions of every factor are obtained. The treatment effectiveness of iron powder and waste scrap iron is compared. It is found that the removal rate of uranium using waste scrap irons is higher than using iron powder. At the end, the removal mechanism of uranium using non-valent iron is discussed, and it fits Langmuir adsorption law.

Key words: uranium-containing wastewater, non-valent iron, adsorption
