【Abstract】 A new water treatment device, which is a combination of cationic exchange and desorption of carbon dioxide in a countercurrent three-phase fluidized bed, was invented. The effects of operation condition of the bed on the quality of effluent water were investigated. Instantaneous conductivity in different section of the column was measured. Ion exchange in the column moved forward in the form of fluctuation. The velocity equation of ion exchange in the bed has been derived.更多还原
