| Abstract: | In the coupling process of polymer enhanced ultrafiltration,macromolecular polyelectrolytes complex metal ions and then are rejected by ultrafiltration membranes.And the coupling process is newly applied in the treatment of wastewater containing heavy metal ions.Based on the introduction of the basic principle and theory of the process,the influences of pH values,metal/polymer ratio,complexation of metallic species simultaneously and ionic strength on complexing process were discussed.At the same time,the effects of temperature,pressure,flow velocity and polymer concentration on ultrafiltration process were concerned,and the regeneration of polymer was also discussed briefly.The results show that the coupling process has a great potential application in the near future. |
