Algae odor collecting device and odor collecting method

The invention discloses an algae odor collecting device. The algae odor collecting device comprises a columnar culture bottle, a light source, an aeration device, a fan, a gas flow meter and an adsorption bottle. The columnar culture bottle is connected with the aeration device through a vent tube, and the controllable light source is mounted on the top of the columnar culture bottle and adjustedby a light source controller. The columnar culture bottle and the adsorption bottle are connected by a collecting tube through the fan, and the gas flow meter can be used for setting the wind speed and time. Adsorption materials with different adsorption characteristics can be placed in the collection tube. The illumination intensity and the aeration intensity can be set for different algae growthconditions, and meanwhile aeration is utilized to drive the release of odorous substances in water. According to a method, the volatilization of the odorous substances is reduced to the maximum extent, extraction of an algae
