高铁酸盐稳定性及氨氮去除情况研究

The Study of Stability and Ammonia-Nitrogen-Removaling Performance of Ferrate

为了克服高铁酸盐溶液容易分解和储存困难的缺点,推动高铁酸盐溶液在净水方面的应用,本文研究了高铁酸盐溶液的稳定性和对生活污水中氨氮的去除效果。实验结果表明,对溶液进行稀释和添加络合剂Na3PO4均有助于提高高铁酸盐的稳定性。氨氮去除效果的实验表明,高铁酸盐对于去除氨氮有显著的效果,其体积和浓度的增加有利于提高氨氮的去除率。

In order to overcome the shortcomings of poor storage stability of ferrate solution, promote the industrial produce and application, the stability of ferrate solution as well as the treatment of ammonia nitrogen in sewage were studied. The experiment result showed that the solution stability can be improved by dilution and adding a complex agent of Na3 PO4. Ammonia nitrogen removaling experiments showed that ferrate had a significant effect on removing ammonia.
