摘　　要：目的观察一种小间距板式催化臭氧消毒机对密闭空间内空气、物体表面消毒效果以及对金属腐蚀性。方法采用载体定量杀菌试验和现场消毒试验方法,对某板式催化臭氧消毒机的消毒效果及其金属腐蚀性进行观察。结果该臭氧消毒机以10 mg/m^(3)臭氧量对空气中白色葡萄球菌作用30 min,平均杀灭率为99.99%;对布片载体上大肠埃希菌作用40 min,对金黄色葡萄球菌作用120 min,杀灭对数值均>3.00。该臭氧消毒机以30 mg/m^(3)臭氧量对纸片载体上枯草杆菌黑色变种芽孢作用3 h,杀灭对数值>3.00。该臭氧消毒机以20 mg/m^(3)臭氧量,循环处理20次,累计60 h,对不锈钢片、碳钢片、铜片和铝片基本无腐蚀。结论该臭氧消毒机在常温下可用于空气和物体表面消毒,对纸片染菌载体可达到高效消毒效果,并且对金属基本无腐蚀性。Objective To observe the disinfection efficacy and corrosiveness to metals of a compact catalytic ozone generator on air and object surface in enclosed spaces.Methods Quantitative carrier tests and on-site tests were carried out to observe the disinfection effect and metal corrosion of an ozone disinfection device.Results The killing rate of the ozone disinfection device on Staphylococcus albus in air was 99.99%with 10 mg/m^(3) ozone for 30 min.For fabric carriers acted with 10 mg/m^(3) ozone,the killing logarithmic values were>3.00 against Escherichia coli for 40 min and against Staphylococcus aureus for 120 min.For Bacillus subtilis var.niger spores on the paper carrier,the killing logarithmic values were>3.00 with 30 mg/m^(3) ozone for 3 h.After being treated with ozone 20 mg/m^(3) for 20 cycles,totaling 60 h,minimal corrosion was observed on stainless steel,carbon steel,copper,and aluminum.Conclusion The ozone disinfection device can be used for air and object surface disinfection at room temperature,achieving highly effective disinfection.It can achieve efficient disinfection of paper bacterial carriers and has little corrosive effect on metals.
