摘　　要：目的了解一种弱酸性电解水生成器的杀菌效能,研究不同消毒学方法对试验结果的影响。方法分别采用2002年版《消毒技术规范》和GB 28234-2011《酸性氧化电位水生成器安全与卫生标准》中杀菌试验方法,对某弱酸性电解水生成器的杀菌效能进行检测。结果依据2002年版《消毒技术规范》,该生成器制备的酸性电解水对大肠杆菌、金黄色葡萄球菌和白色念珠菌作用3.0 min,杀灭对数均值分别为1.97、1.81和0.49;依据GB 28234-2011《酸性氧化电位水生成器安全与卫生标准》,该生成器的酸性电解水对大肠杆菌、金黄色葡萄球菌和白色念珠菌作用3.0 min,杀灭对数值均>5.00。结论不同的试验方法对结果能够产生较大的影响,消毒体系中消毒因子的浓度、试验菌的浓度以及有机干扰物的浓度等都是差异产生的重要影响因素。Objective To study the germicidal efficacy of a weak acid electrolyzed water generator and the effect of different test methods on the experimental results. Methods According to the test methods of Technical Standard For disinfection（ 2002） and GB 28234-2011,the germicidal efficacy of a weak acid electrolyzed water generator was tested and analyzed. Results According to Technical Standard For disinfection（ 2002）,the average killing logarithm values of this water for 3. 0 min were 1. 97,1. 81 and 0. 49 to Escherichia coli,Staphylococcus aureus and Candida albicansrespectively. According to GB 28234-2011,the average killing logarithm values of this water for 3. 0 min were all above 5. 00 to Escherichia coli,Staphylococcus aureus and Candida albicans. Conclusion Different test methods have a great influence on the experimental results. The concentration of test bacteria,disinfection factors and organic substance are important factors affecting the results.
