PROBLEM TO BE SOLVED: To provide a carbon dioxide neutralizing device which can cost effectively execute a neutralization treatment of alkaline waste water by enhancing the utilization efficiency of carbon dioxide. SOLUTION: This device has a gas-liquid mixing means 5, such as a line mixer, which mixes the alkaline waste water and the carbon dioxide, a gas- liquid separating means 21, such as a gas-liquid separator, which separates the carbon dioxide not dissolved in the alkaline waste water and a gas circulating route 24 which circulates and mixes the carbon dioxide separated by the gas-liquid separating means into the alkaline waste water or the carbon dioxide before being introduced into the gas-liquid mixing means or into the gas-liquid mixing means.
