The relationship of dialysis time with wastewater conductivity，saltness，the concentration of sulfates，Ca，Mg and
organic were studied，in order to investigate the dialysis of yam diosgenin hydrolytic wastewater in homogeneous ion exchange
membrane． The results showed that the treatment effect reached steady state after 100 h of dialysis and the conductivity of
wastewater and dialysate were practically equal． The separation efficiencies for saltness，H +
and SO2 －
4 were 71%，62%，
78% respectively． The removal effect of Ca
2 +
was better than that of Mg
2 +
． Most of the organic substances were membrane-
impermeable in the process of dialysis．
