摘　　要：臭氧作为强氧化剂可以用于循环冷却水的处理中。试验研究了影响臭氧杀菌的基本因素,冷却水的pH和水温对处理效果基本没有影响。臭氧的杀菌能力取决于水中的剩余臭氧浓度,臭氧的消耗量与系统中的微生物数量有关。当水中剩余臭氧浓度为0.05mg/L和接触时间为14min时,可以使臭氧的灭菌力达99%。即在循环冷却水系统中,投加0.05mg/L臭氧,就可以控制系统中微生物的生长。由此确定了循环水处理过程中为控制系统中微生物的生长所需维持的最低臭氧浓度。As a strong oxidizer, ozone can be used in the treatment of recycling cooling water. Researches on basic factors of ozone disinfection were done in experiments. Temperature and pH of water almost have nothing with the treating effect. Ozone＇s disinfecting capability depends on ozone reniaining concentration. Ozone＇s consumption relates to the number of microbes in the system. When the remaining concentration is 0.05mg/L and the contacting time is 14 minutes, ozone can disinfect 99% of the microbes. So we can add 0. 05mg/L ozone to the recycling cooling water to check the growing of microbes in the system. Thus the lowest ozone concentration to check the growing of the microbes in recycling cooling water treatment was determined.
