Application of PVC/PVDF Blended Filter Membrane in the Treatment of Algae-Containing Wastewater
A non solvent induced phase separation method was used to prepare PVC/PVDF blended filter membranes.The perfor-mance of different formulations of PVC/PVDF blended filter membranes was analyzed,with a focus on studying the efficiency of PVC/PVDF blended filter membranes in the treatment of algae-containing wastewater.The results showed that through testing the viscosity,mechanical properties,hydrophilicity,porosity,pore size,and water flux performance of PVC/PVDF blend filter mem-branes with different formulations,it was found that the PVC/PVDF blend filter membrane had the best performance when the mass fraction of PVDF was 6%,and its treatment efficiency on algae-containing wastewater was studied.The PVC/PVDF blend filter membrane has a higher interception efficiency on solid suspended solids(SS),and it had a good retention effect on algae.This meth-od has certain practical guiding significance for the treatment of seaweed wastewater.
