The Ca(superscript 2+) salt solution as a new regenerant was presented in this paper. The influences of the calcium salt proportioning, temperature, dosage and flow rate on anion exchange fiber regeneration were studied. High regeneration can be obtained with 0.5mol/L CaCl2+8g/L CaO+6.5 °Bx sucrose solution at 70~80℃, the dosage of the Ca(superscript 2+) salt solution was about half of the raw decoloring syrup, the regenerant flow rate should be lower than that of the raw decoloring syrup. It was shown that stable decolorization rate and lower decline in exchange capacity could be achieved with the new regenerant. It performed more effectively than the traditional sodium salt regenerant with less discharge of waste water.
