PURPOSE:To remove efficiently gaseous carbon dioxide in a short time by dispersing compressed air, which is atomized through a porous partition wall, into water to bring the air into close contact with water. CONSTITUTION:By driving a blower 5 and opening a valve 10, the compressed air is introduced into a bubbling chamber 2, and atomized through a partition wall 4 to bubble the water flowing on the surface of the chamber. The water rises in bubbles up to the ceiling of the bubbling chamber 2, then pressed to the side of an overflow wall 11, and overflowed from the overflow wall 11 into a gas-liquid separation chamber 12, wherein the air contg. gaseous carbon dioxide is separated from the water. The sending pressure of the air to be supplied is set strong enough so that the flow of the bubbles from the partiton wall 6 to the gas-liquid separation chamber 12 may not be disturbed by the remaining water in the bubbling chamber 2, and the amt. of the air is set to be enormous enough as compared with the water supply to a water spouting tube 8. The water after treatment is discharged from a discharge port 14 to a water storage tank 13.
