| Abstract: | The composition of ion exchange resin regenerated waste liquid was analyzed in refined sugar mill, and the membrane filtration technique was researched according to the characteristics. The results showed that the permeate reuse rate was more than 80% and the pigment could be extracted from concentrated solution through ion exchange resin regenerated waste liquid in refined sugar mill dealed with process of "chemical pretreatment-0.45 μm ceramic membrane ultrafiltration treatment- nanofiltration- concentrated solution- pigment extraction (cyclic utilization of permeate)", the effluent zero emissions was realized in refined sugar mill and the pigment could be extracted, which produced some economic and social benefits to the sugar mill. |
