<p>A carbon dioxide recovery system includes a carbon dioxide absorption tower (20) for absorbing carbon dioxide in combustion exhaust gas into an absorbing solution by bringing the combustion exhaust gas into contact with the absorbing solution that absorbs carbon dioxide; a dissolved oxygen removing device (20) that uses at least one device of a device for blowing bubbling gas into the rich absorbing solution into which carbon dioxide has been absorbed, a device for applying ultrasonic oscillation, and a device for heating the rich absorbing solution; a bubble removing device (30) that turns the rich absorbing solution into which carbon dioxide has been absorbed in the carbon dioxide absorption tower (20) into a swirling flow or agitates the rich absorbing solution; and a regeneration tower (40) that regenerates the absorbing solution by releasing carbon dioxide from the absorbing solution from which oxygen has been removed by the dissolved oxygen removing device (20) and the bubble removing device (30) and obtains carbon dioxide gas.</p>
