三种空气消毒方法消毒效果的比较

为了解三种消毒方法对室内空气消毒效果,采用现场试验方法对二氧化氯气溶胶喷雾、臭氧熏蒸和氯溴异氰尿酸烟雾剂熏蒸等三种方法进行了比较观察。结果,用50 mg/L二氧化氯按20 m l/m3用量进行气溶胶喷雾作用90 m in,对室内空气中自然菌消亡率91.58%。用10 mg/m3臭氧熏蒸作用60 m in,对空气中自然菌消亡率为82.00%。用氯溴异氰尿酸烟雾剂按照0.3 g/m3用量进行烟雾熏蒸作用120 m in,对空气中自然菌消亡率为80.63%。结论,三种消毒法对空气中自然菌都有杀灭作用,但以二氧化氯气溶胶喷雾法效果最好且用药量低。

COMPARISON OF DISINFECTION EFFICACY OF THREE AIR DISINFECTION METHODS

In order to know the efficacy of three disinfection methods in disinfection of indoor air,on-the-spot trial method was used to carry out comparative observation on three methods including chlorine dioxide aerosol spray,ozone fumigation and chlorobromoisocyanuric acid smoke agent fumigation.Results: Aerosol spray of 50 mg/L chlorine dioxide at a dose of 20 ml/m~3 with a 90 min dwelling time eradicated 91.58% of natural bacteria in indoor air.Funigation with 10 mg/m~3 ozone for 60 min eradicated 82.00% of the natural bacteria in air.Smoke fumigation of chlorobromoisocyanuric acid smoke agent at a dose of 0.3 g/m~3 for 120 min eradicated(80.63%) of the natural bacteria in air.Conclusion: All the three disinfection methods have certain killing effect on the natural bacteria in air,but chlorine dioxide aerosol spray has the best efficacy and its dosage is low.
