%X Relationship between biomass,Fe2+ concentration and Fe2+ oxidation rate in sequencing batch reactor(SBR)was investigated to produce bio-polymeric ferric sulfate coagulant(BPFS).Results revealed that larger initial inoculums concentration and lower initial ferrous ion concentration induced the higher ferrous ion oxidization rate under the experimental conditions.There existed a linear relationship between the remainder Fe2+ concentration and reacting time.The optimal conditions for the bacteria to get the highest ferrous oxidation rate may be with the Fe2+ concentration of 20 g/L and the initial inoculums concentration of 8×108/mL.Jarosite was synthesized during the ferrous biological oxidation process.After being dried,the essential properties of BPFS completely met PRC’s state standard.BPFS’s performance in seawater coagulating compared with a commercial product were investigated,results showed that BPFS performed better than chosen commercial product in seawater turbidity removal.
