Abstract:Because of its broad spectrum and high efficiency, the microwave disinfection was used to control the airborne microbial contaminates in VAC system. Some microwave disinfection devices were developed combined with air filter, the design and calculation method was presented, and the disinfection effects on White staphylococcus, Staphylococcus aureus, Bacillus Subtilis, Escherichi coli were measured. The results show that the major influence factors on disinfection effect are microwave power, water-content of filter material, disinfecting duration. After 15 min, the kill ratio is >90%, and the log value is >1. The microwave field is uniform and the kill effect of bacteria on each surface of filter is the same, without statistically significant difference.
