摘要
本文根据地铁中存在的细菌种类,提出了采用光等离子改善地铁环境空气质量,并介绍了光等离子灭菌原理,分析了其对不同菌种的灭菌效果,实验结果表明对白色葡萄球菌的灭菌率在99.94%以上,物表金黄色葡萄球菌的灭菌率为99.3%,对耐甲氧西林金黄色葡萄球菌(MRSA)的灭菌率为77.1%,说明光等离子技术可以有效地消灭广州地铁所检出的菌种,可以有效地改善广州地铁的空气质量,确保公众出行健康,营造良好的乘车环境。
According to the type of bacteria present in the subway,proposed the use of plasma to improve air quali-ty in the metro environment,and introduces the plasma sterilization principle,analyzes its sterilization effect of dif-ferent strains,the experimental results show that the sterilization rate of white staphylococcus more than 99.94%, sterilants table Staphylococcus aureus was 99.3%,and sterilization methicillin -resistant Staphylococcus aureus （MRSA）rate of 77.1%,indicating that plasma technology can effectively eliminate the detected bacteria of Guang-zhou Metro,can effectively improve the air quality in Guangzhou subway,ensure public travel health,to create a good traveling environment.
