摘要：Through beaker test, it was analyzed the effect on the removal of turbidity, chroma and UV 254 in PI River water with low turbidity by poly-ferric sulfate(PFS).The results showed that it has good effect on removing turbidity and chroma by adding PFS, but it was normal to UV 254 , not exceed 50%,with the increase of PFS dosage, the turbidity and chroma removal trend is similar to that of UV 254 . For turbidity removal, the optimal dosage of PFS was 70 mg / L, and for UV 254 removal, the optimal pH value range is not neutral, and it is speculated that PFS mainly neutralizes pollutants during coagulation in PI River water.
