As detection showed, such a sanitary system of air disinfection, integrated by ultraviolet air disinfection and Grade Ⅱ filters can reach the same standard of cleanliness as a high efficiency particle filter. This system easily satisfies the cleaning of air in hospital wards, surpassing the sterile air standards and the requirements of the National Bacteria Indicator （NBI）. As a result of this system＇s efficiency, resources and running costs can be reduced dramatically. Therefore, revision of the national standards of Structural Technical Specification of the Cleaning Operation Department needs to move forward.展开更多

However, in the stage of garden engineering construction, some environmental pollution problems often occur. In order to improve the problems and strengthen the construction of conservation-oriented garden engineering, it is an important means to ensure the urban ecological environment. On the basis of ensuring the effect and quality of garden construction, the impact of construction on the environment is reduced. This paper mainly focuses on the research and analysis of the application of ecological measures in conservation-oriented garden projects, hoping to provide reference for the future construction and development of garden projects.展开更多
