Abstract：
Starting from biological cleaning technology, analyses the relationship between environmental microbe and hospital infection and between microbial aerosol particle size and bacteria killing or eliminating. Explains that the setting of double standards in China’s Architectural technical code for hospital clean operating department is essential and advanced. Points out that ultraviolet irradiation technology in biological cleaning system has some disadvantages and it can not replace high efficiency particulate air filters.
