Abstract：Objective The purpose of this study is to explore the application of nano-photocatalyst in the exhaust emission of
medical center negative pressure suction system, to achieve the purpose of purified exhaust emission, and to improve the level of
decontamination of medical exhaust in modern large- and medium-sized hospitals. Methods In this paper, we proposed the current
situation of exhaust emission of medical center negative pressure suction system and the treatment method of the exhaust. We set a
purification link for the pollution exhaust by adding a photocatalyst purification box in the suction system. The ultraviolet catalyzed
photocatalyst was used to purify the pollution exhaust. Results The purification rate of the exhaust purified by nano-photocatalyst
was more than 90%. Conclusion In this study, the exhaust from the suction system was discharged after purification using our
purification device, making the exhaust purification simple and feasible.
