摘　　要：测定了三相逆流离子交换-除CO2联合水处理床中不同截面和不同径向位置的瞬时电导率，探讨了联合水处理床中离子交换的变化规律，研究了运行工况对出水电导率的影响，推导出了这种床中离子交换的速度方程式。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.
