Zusammenfassung:	To provide a fluid treatment method and apparatus capable of improving the effect of regenerating an adsorption function. A method of reducing the concentration of carbon dioxide included in air-to-be-treated includes the following steps. The air-to-be-treated is caused to pass through a first rotor (10) to thereby reduce the concentration of water in the air-to-be-treated and is thereafter caused to pass through a second rotor (20) to thereby reduce the concentration of carbon dioxide in the air-to-be-treated. This second rotor (20) has a zeolite capable of adsorbing both carbon dioxide and water, and the lower its temperature is, the more efficiently it can adsorb carbon dioxide. When thermally regenerating the second rotor (20), air whose water concentration has been reduced in the first rotor (10) and which has been heated by a heater (8) is used.
