| Abstract: | The distribution of gas holdup of a combined water treatment device of three-phase(solid, liquid, gas) fluidized cationic exchange -CO 2 removal was studied under a certain conditions. The effects of operational conditions and amount of resin added on the device were discussed. A two dimensional pseudo-two-phase fluid dynamic model was used to calculate values of gas holdup in a combined water treatment of three-phase fluidized cationic exchange -CO 2 removal, and the simulating results were compared with the exprimental ones, indicating that both is consistent with each other. |
