摘　　要：目的评价一种稳定型含氯消毒剂的室内空气消毒效果。方法以空气中常见的表皮葡萄球菌为实验菌株,选用0.4%的硫代硫酸钠为中和剂,对稳定型含氯消毒剂进行了定量杀菌实验、实验柜杀菌实验、模拟现场消毒实验、现场消毒实验,并进行了稳定型含氯消毒剂与其他消毒剂的对比实验,以及消毒剂的稳定性实验,得出该稳定型含氯消毒剂对空气中自然菌的消亡率。结果定量杀菌实验结果显示,197.1mg/L的稳定型含氯消毒剂消毒2min,或在3%牛血清白蛋白干扰下消毒20min;1158mg/L的稳定型含氯消毒剂消毒1min,或在3%牛血清白蛋白干扰下消毒5min,对表皮葡萄球菌的杀灭率均可达到100%。实验柜杀菌试验和模拟现场试验结果显示,1158mg/L的稳定型含氯消毒剂消毒30min后,空气中表皮葡萄球菌的杀灭率分别为99.08%和99.07%。现场试验结果表明,1158mg/L的稳定型含氯消毒剂,使用量为20ml/m3,消毒30min后,空气中自然菌的消亡率为90.62%。用于空气消毒时,稳定型含氯消毒剂与次氯酸钠和三氯异氰尿酸的消毒能力相当,但消毒后的空气无明显气味。结论该稳定型含氯消毒剂可用于空气消毒。Objective To evaluate the indoor air disinfection effect of a stable chlorine disinfectant. Methods By using sodium hyposulfite as the neutralization compound, the quantitative disinfection experiments, simulation scene disinfection and the scene disinfection were carried out and a comparison with other disinfectants was made to evaluate the efficiency of the stable chlorine disinfectant. Results When the stable chlorine disinfectant was used in the conditions of an effective chlorine content of more than 1 158 mg/L, a dosage of 20 ml/m3 and a disinfection duration of 30 min, the killing rate of natural bacterium in the air was 90.62%. The stable chlorine disinfectant had a similar capability to sodium hypochlorite and trichloroisocyanuric acid in air disinfection, but it did not produce the obvious odor in the disinfected air. Conclusion The stable chlorine disinfectant tested in the present study is applicable to air disinfection.
