Production of bio-polymeric ferric sulfate coagulant by sequencing batch reactor
摘要
Abstract
Relationship between blomass, Fe^2＋ concentration and Fe^2＋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 ox- idization rate under the experimental conditions. There existed a linear relationship between the remainder Fe^2＋concentration and reacting time. The optimal conditions for the bacteria to get the highest ferrous oxidation rate may be with the Fe^2＋ concentration of 20 g/L and the initial inoculums concentration of 8 ×10^8/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 seawa- ter turbidity removal.关键词
