The invention provides a compressed biological aerosol disinfection device, method and system and a use method, and belongs to the technical field of drainage systems. The device comprises a contact cylinder, a spiral baffle, a hollow rotating shaft, an ultraviolet lamp tube, a water replenishing pipe, a high-frequency atomizer, a water storage cylinder, a photocatalyst coating and a shaft bracket. Aiming at different fan flows of ventilation systems of different drainage pumping stations, airflow can be compressed to a certain degree through the spiral baffle so as to prolong the stagnation time of the airflow in a disinfection area, and the disinfection efficiency is improved; a large number of micron-sized water drops formed by water surface fragmentation excited by the high-frequency atomizer are used for trapping microorganisms in gas and supplementing free radicals for the surface of the photocatalyst, so that stable operation of the ultraviolet-photocatalysis combined disinfection system is ensured. 本发
