【摘要】：目的探讨饮用水臭氧水机的评价方法,为市场准入提供安全有效的检测评价方案。方法在臭氧水机的额定产水量内,自来水以1.0 L/min流速流经该净水器,通过中和剂鉴定、总体性能、饮用水消毒效果、臭氧水定量杀菌等试验对饮用水臭氧水机的安全及应用效果进行评价。结果含0.2%硫代硫酸钠、0.2%吐温-80的0.03 mol/L PBS溶液的中和剂和中和产物对大肠杆菌及培养基无不良影响。总体性能试验、饮用水消毒效果试验符合《生活饮用水消毒剂和消毒设备卫生安全评价规范》(试行)和GB 5749—2006《生活饮用水卫生标准》的要求;当作用时间达到30 min时,该臭氧水机产生的臭氧水对染菌载体上的大肠杆菌、金黄色葡萄球菌、铜绿假单胞菌杀灭的对数值均大于3,符合《消毒技术规范》(2002)的要求。结论通过中和剂鉴定、总体性能、饮用水消毒效果、臭氧水定量杀菌等指标可对臭氧水机的使用安全性能及消毒应用效果等做出全面的评价。
[Abstract]:Objective to explore the evaluation method of drinking water ozone water machine and to provide a safe and effective test and evaluation scheme for market access.Methods within the rated water production of ozone water machine, tap water passed through the water purifier at a flow rate of 1.0 L/min. The overall performance and disinfection effect of drinking water were evaluated by neutralizer.The safety and application effect of ozone water machine were evaluated by ozone water quantitative sterilization test.Results the neutralizer and neutralization product of 0.03 mol/L PBS solution containing 0.2% sodium thiosulfate (0.2% Tween-80) had no adverse effects on Escherichia coli and culture medium.The overall performance test and the drinking water disinfection effect test meet the requirements of the Standard for Sanitary Safety Evaluation of domestic drinking Water disinfectants and Disinfection Equipments (for trial implementation) and GB5749-2006 for drinking Water Sanitation Standards. When the working time reaches 30 min,The ozone water produced by the ozone water machine can kill Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa on the carrier of bacteria more than 3, which meets the requirements of Technical Specification for Disinfection (2002).Conclusion through the identification of neutralizer, overall performance, disinfection effect of drinking water and quantitative sterilization of ozone water, the safety performance and disinfection application effect of ozone water machine can be comprehensively evaluated.
