| Abstract: | Based on the study of the flocculation property of polymeric ferric sulfate(PFS),this research adopts the chemical precipitation method to make nano-Fe3O4 and studies the intensified effort by nano-Fe3O4 on PFS flocculation property.It is found that nano-Fe3O4 can intensify the flocculation effect of PFS and accelerate the sedimentation of alum.Nano-Fe3O4 is obviously better than other traditional flocculants such as PFS,PAC,FeSO4 in dealing with the decolorization rate on washing wastewater treatment in clothing factory,COD removal rate and floc settling velocity.Decolorization rate and COD removal rate reached 95.3% and 80.4% respectively. |
