摘要
目的观察二氧化氯消毒剂对空气消毒效果。方法采用空气微生物采样器采样和培养方法,对二氧化氯喷雾气溶胶消毒空气的效果进行了实验室和现场试验。结果用含量为585 mg/L二氧化氯消毒剂水溶液,按14ml/m3用量进行气溶胶喷雾,作用30 min,对试验柜内空气中白色葡萄球菌平均杀灭率达到99.90%以上。以相同浓度和用量进行气溶胶喷雾,对室内空气中自然菌平均消除率达到90%以上。结论二氧化氯气溶胶状态对室内空气中人工污染菌和自然菌杀菌效果均达到消毒标准要求。
Objective To observe the air disinfection efficacy of chlorine dioxide disinfectant.Methods The microbiological aerosol sampler and the culture method were used for laboratory and field air disinfection tests of chlorine dioxide arosol.Results Aerosol spraying disinfectant containing 585 mg/L chlorine dioxide of 14 ml/m3 for 30 min could kill 100% of Staphylococcus albus sprayed artificially in aerosol chamber.In the field trial,the same dosage for 30 min could eliminate over 90% natural bacteria in indoor air.Conclusions The efficacy of chlorine dioxide spray in killing artifically contaiminating bacteria and natural bacteria in indoor air can reach the requirement of disinfection standards.
