Abstract: The structure of an exhaust gas treatment apparatus is simplified so that dissolved oxygen concentration and pH of a froth layer can be maintained at a value within a predetermined range even if the number of gas risers of the exhaust gas treatment apparatus is reduced. The exhaust gas treatment apparatus has a sealed vessel 21. The sealed vessel 21 is vertically partitioned into two spaces by a partition 22. The space under the partition 22 is an absorbing liquid storage portion 24, and the space above the partition 22 is an exhaust gas introducing portion 26. The partition 22 is provided with a gas riser 30 for deriving treated exhaust gas from an upper space 24a of the absorbing liquid storage portion 24. A large number of sparger pipes 29 are provided in a effective region where the gas riser 30 of the partition 22 is not provided, so as to reach inside an absorbing liquid stored in the absorbing liquid storage portion 24. A non-jet region where the sparger pipe 29 is not provided is provided in the effective region. The froth layer is not formed in the non-jet region, and the absorbing liquid in a foamed state flows down from the froth layer therearound to circulate the absorbing liquid.
