摘要

目的 观察有效氯浓度、温度、有机干扰物对微酸性电解水消毒效果的影响.方法 采用悬液定量和载体定量杀菌试验方法对某微酸性电解水杀菌效果进行观察,分析其影响因素.结果 该微酸性电解水有效氯含量范围为52.4～160.4 mg/L.有效氯含量为52.4 mg/L的微酸性电解水作用0.5 min,可杀灭悬液中的大肠埃希菌;有效氯含量为160.4 mg/L的微酸性电解水作用5.0 min,可杀灭悬液中的枯草杆菌黑色变种芽孢.在0℃和10℃条件下,有效氯含量为160.4 mg/L的微酸性电解水作用0.5 min,可杀灭载体上的大肠埃希菌;作用30 min,对载体上的枯草杆菌黑色变种芽孢平均杀灭对数值分别为2.46和3.55.有机干扰物会降低微酸性电解水的消毒效果.结论 有效氯浓度、作用温度和有机干扰物均可显著影响微酸性电解水的消毒效果.

Abstract

Objective To observe the influence of available chlorine,temperature and organic interference substances on disinfection effect of slightly acidic electrolyzed water.Methods Suspension quantitative and carrier quantitative germicidal tests were used to observe the influencing factors of germicidal efficacy of a slightly acidic electrolyzed water,and influencing factors were analyzed.Results The available chlorine content of the slightly acidic electrolyzed water ranged from 52.4 mg/L to 160.4 mg/L.With the 52.4 mg/L available chlorine and the contact time of 0.5 min,E.coli in the suspension was killed.With the 160.4 mg/L available chlorine content and the contact time of 5.0 min,Bacillus subtilis var.black spores were killed.In temperature environments of 0℃and 10℃,E.coli on the carrier was killed with 160.4 mg/L available chlorine content and the contact time of 0.5 min.With the contact time of 30 min,the average killing log values of Bacillus subtilis var.black spores on the carrier were 2.46 and 3.55,respectively.Organic interference would reduce the disinfection effect of slightly acidic electrolyzed water.Conclusion The concentration of available chlorine,reaction temperature and organic interference substances are important factors affecting the disinfection effect of slightly acidic electrolyzed water.
