摘　　要：目的观察过氧化氢对物体表面和室内空气的消毒效果。方法通过现场模拟评价和现场评价方法,对过氧化氢消毒物体表面和室内空气的效果进行评估。结果以35 g/L过氧化氢消毒液进行常量喷洒,对物体表面大肠埃希菌和金黄色葡萄球菌标准株作用15 min,杀灭对数值均>3.00;用105 g/L过氧化氢进行常量喷洒消毒,对食品生产车间物体表面作用30 min,其自然菌平均杀灭率>90%。用气溶胶喷雾作用30 min,对室内空气中自然菌的消毒效果达到合格要求。结论用过氧化氢消毒液对物体表面和室内空气进行常量喷洒和气溶胶喷雾,具有较好的消毒效果。Objective To observe the disinfection effect of hydrogen peroxide on object surface and indoor air.Methods Field simulation and field evaluation test were applied to evaluate the disinfection effect of hydrogen peroxide on object surface and indoor air.Results The killing log valve was>3.00 for Escherichia coli and Staphylococcus aureus standard strains with 35 g/L hydrogen peroxide for disinfection of 15 min.The average killing rate of natural bacteria on objects surface was above 90%with 105 g/L hydrogen peroxide for disinfection of 30 min at food production workshop,and the disinfection effect of natural bacteria of indoor air reached the qualified level by aerosol spraying for exposure of 30 min.Conclusion Spraying and aerosol spraying with hydrogen peroxide disinfectant are effective on object surface and indoor air disinfection.
