| 摘 要： | The cooling water was the major part of industrialwater, and its quantity was above 90%1]. Since1970s, as the research of high efficiency inhibitor,such as organic polyelectrolyte and phosphate ester, thealkaline treatment approach of cooling water becamemore popular; and tended to be high concentration andhigh pH.This led to the low disinfection effect of somepreparation containing chlorine. Chlorine dioxide was ahigh effect disinfectant2], being used widely in circu-lating cooling water in…

| Abstract: | The disinfection effect of chlorine dioxide, chlorine and their mixture on heterotrophic bacteria, iron bacteria and sulfate-reducing bacteria in circulating cooling water was studied. The results of the test indicated that high purity chlorine dioxide was the most effective biocide in the 3 disinfectants, and with a dosage of 0.5mg/L, chlorine dioxide could obtain perfect effect. High purity chloride dioxide could have the excellent effect with the pH value of 6 to 10, and could keep it within 72 h. Chlorine and their mixture couldn't reach the effect of chlorine dioxide. |
