The invention discloses a tower-type super fine bubble reactor. The tower-type super fine bubble reactor comprises a body, a primary bubble breaker and a secondary bubble breaker, wherein a reaction cavity is formed in the body, a through hole, a liquid inlet, a circulating liquid outlet, an air inlet and a circulating air outlet are formed in the wall of the reaction cavity, one part of the primary bubble breaker penetrates through the through hole and extends into the reaction cavity, the primary bubble breaker is provided with a circulating liquid inlet, a circulating air inlet and an air-liquid mixture outlet, the circulating liquid inlet is communicated with the circulating liquid outlet, and the circulating air inlet is communicated with the circulating air outlet. The secondary bubble breaker is provided with a feeding port and a discharging port, and the feeding port is communicated with the air-liquid mixture outlet. The tower-type super fine bubble reactor has the advantages of being high in mass transfer efficiency, high in reaction rate, low in energy consumption and the like, the reaction time can be remarkably shortened, and reactor size can be decreased.
