| 摘 要： | 目的 观察真空臭氧消毒机对家庭饮用水的消毒效果。方法 以大肠杆菌（Escherichia coli)8099作为指示菌，按照 GB /T5750-2006《生活饮用水标准检验方法》对不同水量、水温、盛水容器下的饮用水消毒效果进行检测。结果 当消毒机箱内压强为50 kPa时，对各水样消毒15 min后，50、100、150 ml水样的平均杀灭率分别为（79.14±0.01）%、（70.99±0.00）%、（64.12±0.02）%；常温（22℃）和低温（4℃）水样的平均杀灭率分别为（70.99±0.00）%、（92.01±0.00）%；100 ml烧杯、250 ml烧杯、平皿（150 mm）所盛放水样的平均杀灭率分别为（67.48±0.01）%、（70.99±0.00）%、（97.75±0.00）%。结论 在本实验条件下，所用真空臭氧消毒机对家庭饮用水中的大肠杆菌有一定的杀菌效果，具有开发成为家庭日常杯量饮用水消毒机器的潜力。

| Abstract: | Objective To observe the disinfection effect of vacuum ozone disinfector on family drinking water. Methods Escherichia coli 8 099 was used as the indicator microorganism to test the disinfection effect of drinking water under different water yield, water temperature and water container according to GB /T5750-2006 Standard Test Method for Drinking Water". Results Under the condition that the pressure was 50kPa in the disinfection the water samples for 15 minutes, , the average killing rate of 50 ml, 100 ml, 100 ml water samples were (79.14±0.01)%, (70.99±0.00)%, (64.12±0.02)%, respectively. The average killing rate of room temperature (22℃) and low temperature (4℃) water samples were (70.99±0.00)%, (92.01±0.00)%, the average killing rate of the sterilization of 100ml beaker, 250ml beaker, and plate was(67.48±0.01)%, (70.99±0.00)%, (97.75±0.00)% after disinfection of all water samples for 15 min. Conclusion Under the condition of this experiment, the vacuum ozone disinfector has a certain bactericidal effect on the Escherichia coli in family drinking water, and has the potential to develop for drinking water disinfection in the household daily cup. |
