摘　　要：目的石研究缓释型固体二氧化氯以气体释放方式对密闭空间物体表面消毒效果。方法采用载体定量杀菌试验方法,对不同条件下缓释型固体二氧化氯对细菌繁殖体杀灭效果进行观察。结果缓释型固体二氧化氯有效含量和数量、加人试剂种类及加入量、试验菌种、染菌载体类型、消毒剂与染菌载体距离均为缓释型固体二氧化氯对密闭空间物体表面消毒的重要影响因素。在室温10~15℃,相对湿度为20%~30%条件下,30片9.35mg/片缓释型固体二氧化氯加人7.5mL水,消毒作用4h,消毒剂与染菌载体距离为60cm时,通过调整消毒剂放置方式,可实现固体二氧化氯对密闭空间物体表面的消毒。结论缓释型固体二氧化氯加水活化后,在一定空间范围内对常见物体表面有较好的杀菌效果。Objective To study the disinfection effect of sustained release solid chlorine dioxide on the surface of objects in confined space by gas release.Methods The inactivation effect of sustained release solid chlorine dioxide on bacterial propagules under different conditions was observed using the carrier quantitative bactericidal test.Results The effective content and quantity of sustained release solid chlorine dioxide,the type and amount of reagent added,the test bacteria,the type of bacteria carrier,and the distance between disinfectant and carriers were all the important factors affecting the object surface disinfection in confined space for sustained release solid chlorine dioxide.Under the conditions of room temperature of 10-15℃and relative humidity of 20%-30%,solid chlorine dioxide could achieve effective disinfection on the object surface in confined space by adjusting the placement mode of disinfectants when 30 tables of 9.35 mg/table sustained release solid chlorine dioxide were added to 7.5 mL of water and acted for 4 h of disinfection,and the distance between disinfectant and bacteria carriers was 60 cm.Conclusion After sustained release solid chlorine dioxide is activated by adding water,it has good bactericidal effect on the surface common objects within a certain space range.
