The effect of different hydrolysis characteristic of poly-ferric sulfate (PFS) on the coagulation in starch wastewater is mainly studied. By jar tests, the effect of the PFS dosage and the pH value of the wastewater on the coagulating efficiency of the PFS in starch wastewater is analysed. The tests show that the coagulating efficiency is the best when the alkalinity is between 0.1 ~ 0.2. With the prolonging of aging time, the middle polymeric PFS is converted into the high polymeric PFS, the coagulating efficiency of PFS is getting lower. It is feasible to treat starch wastewater with PFS. The removal rate of COD can be as high as 80%.
