Abstract: |
In order to make use of the advantage of membrane separation and supported photocatalystcoupling technology, TiO2-doped PVDF membrane was prepared by the nonsolvent induced phase method, and theeffect of process conditions (such as UV light intensity, membrane filtration flow rate, solution concentration) on membrane performance were studied by self-made testing device, ultraviolet-visible spectrophotometer and scanning electron microscope(SEM), and the optimal process condition was obtained. Results indicated thatthe foulants’ rejection and photocatalytic degradation could be got simultaneously by the coupling technology. And the optimal removal of humic acid could be attainedwhen the UV light intensity was 1.0mW/cm2, the flow rate was 300mL/min, and the solution concentration was 2mg/L. |
