【摘要】 研究了不同 ｐＨ、 Ｆｅ２＋浓度及接种量对氧化亚铁硫杆菌生长的影响；在此基础上，以 Ｈ－２软性填料为载体，固定氧化亚铁硫杆菌．构建了固定床生化反应器．考察了不同稀释 率、通气量下固定床生化反应器氧化 Ｆｅ２＋的情况，最大氧化反应速率可达４ｇＥｅ２＋／ｈ．更多还原

【Abstract】 Thiobacillus ferrooxidans growth were investigated at different conditions: PH, ferrous iron concentration, and cell numbeL Depend on the study, a packed-bed bioreacter was developed which contained H-2 foam as biomass support particles for Thiobacillus ferrooxidans immobilization. With this bioreacter, the maxium Fe2+ oxidation rate of 4g/h was attained. The oxidation of ferrous iron at different dilution was studied in the packed-bed bioreactor更多还原
