空气消毒净化方法研究

为寻找安全、有效、无毒、无害的空气消毒净化方法，还医院一个绿色环境，本研究选用永健 Ｋ Ｊ Ｄ１２００ Ａ 灭菌型静电空气消毒净化器，对医院环境进行空气细菌、二氧化硫、二氧化碳、一氧化碳、二氧化氮、甲醛６ 项指标进行现场及实验现场的杀菌、净化研究。实验结果表明，使用现场在额定电压下，可１００ ％ 杀灭现场空气中的细菌，而低于额定电压下其杀菌率达８４ ．３ ％ ～９６ ．７ ％ ，在连续８ 人流动污染，开机净化下空气细菌数稳定地保持在１００ ～２００ Ｃ Ｆ Ｕ／ Ｍ３ ，在５０ 支香烟污染２ｈ 后开机净化，对一氧化碳、二氧化氮、烟尘、异味等有较好的净化效果，对高浓度甲醛和二氧化硫的污染也有一定的净化作用，而对二氧化碳无明显的净化效果。

Research on Air Disinfection and Purification

A study is conducted to find an environment-friendly methods of air disinfecting and purification which is safe,effective and innocuous in hospital.Experiments were carried out on Yongjian KJD1200A electrostatic bactericide air cleaner.It is tested in two conditions by six index:air bacteria,sulfur dioxide,carbon dioxide,carbon monoxide,nitrogen dioxide and formal dehyde. In work field,bacteria in the air is 100% destroyed if the cleaner runs at normal voltage and bacteria in the air is destroyed at rate 84.3%-96.7% if it runs below normal voltage.In the area mobile polluted by eight person,running of the cleaner makes the bacteria number steadily remain at the rate of 100-200CFU/M3.In area polluted by 50 cigarettcs burning at stretch in 2 hours,the cleaner is run to purifying the air:it removes carbon monoxide,nitrogen dioxide,smoke dust and smell completely,partly removes formol dehyde and sulfur dioxide but has no effect on removing carbon dioxide.
