英文摘要：

In order to analyze the existing problems in the study of photocatalytic disinfectant technology and the restricting factors of its development, this paper has analyzed the study progress of photocatalytic disinfectant technology in the humidity influence, photocatalyst modification and photocatalyst immobilized film technology based on the disinfection＇s mechanisms. The application of the disinfectant technology in water treatment, central air condition system sterilization, painting and electrical equipment were introduced. It has been pointed out that the key point of transfering the photocatalytic disinfectant technology to industry is the interdisciplinary research among different domains. The future about the photocatalytic disinfectant technology was described.
