Abstract:

The character of the circulating cooling water containing ammonia and the performance of chlorodioxide in this kind of water are analysed. emphatically on the chemical change of chlorodioxide when nitrobacteria are in existence. On the basis of making a summary on the result in practice,it is affirmed that chlorodioxide has unique bactericidal effect on the ammoniacontaining water. An effective bactericidal project to treat circulating water that contains ammonia has been put forward. This method can assure that the total number of bacteria and the amount of nitrite can meet the requirement of the National Standard.

Key words: ammonia, circulating cooling water, chlorodioxide, sterilization

摘要：

分析了含氨循环冷却水的特点和二氧化氯在此类水中的表现。重点分析了二氧化氯在硝化菌类存在下的化学变化。在总结实际应用效果的基础上, 肯定了二氧化氯在含氨水中有独到的杀菌作用。提出了对含氨循环水行之有效的杀菌方案。应用该方案杀菌, 完全能保证循环水中异养菌总数及亚硝酸根达到国标要求。
