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
