Peking University, striving to be a top university in world, has made rapid progress in research and teaching, resulting in the subsequent increase in the production of hazardous waste in laboratories. How to ensure the safety and temporary storage of these hazardous wastes during campus hours has become an important part of the laboratory safety management and environmental protection work. We manage the hazardous waste by classification according to its different natures. We have also optimized the structure of the cabinet for temporary storage of hazardous chemical waste. The VOCs volatilized in the temporary storage environment were monitored, and the purification test of the polluted gas was carried out by using the titanium dioxide nanowire photocatalyst. It was found that all detected pollutants could be degraded by the catalyst, which showed that photocatalytic technology is a promising method used to solve the complex VOCs pollution problem in campus hazardous waste temporary storage.
