摘要

氧化亚铁硫杆菌（A.ferrooxidans）介导的生物矿化方法促使可溶性Fe向次生铁矿物转变对酸性矿山废水（AMD）治理具有重要意义.化能自养菌A.ferrooxidans易受水流冲击而流失，常采用固定化方式来提高菌密度，从而保证较高的Fe²⁺氧化和成矿速率以满足实际需要.本研究在相同初始条件下（pH=2.30、Fe²⁺浓度4.48g/L、A.ferrooxidans密度8×10⁶cells/mL）生物合成固定有A.ferrooxidans的施氏矿物、黄钾铁矾和黄铵铁矾，比较矿物溶解前（固定态）和溶解后（游离态）A.ferrooxidans的Fe²⁺氧化性能，并分析各矿物对A.ferrooxidans的固定能力.结果表明，生物成因次生铁矿物干重排序为施氏矿物（0.24g） < 黄铵铁矾（0.35g） < 黄钾铁矾（0.67g），但矿物固定A.ferrooxidans的能力却依次为施氏矿物 > 黄铵铁矾 > 黄钾铁矾.以游离态A.ferrooxidans的Fe²⁺氧化速率作为参比，推算出本研究所得施氏矿物、黄铵铁矾、黄钾铁矾固定A.ferrooxidans的有效生物量依次为5.33×10⁷~ 5.33×10⁸，5.72×10⁶~5.72×10⁷，6.35×10⁶cells/g（干基）.次生铁矿物载体有效生物量不仅直接影响AMD体系中Fe²⁺氧化速度，也间接决定了总Fe的矿化去除效果.

Abstract：

Biomineralization mediated by A.ferrooxidans to promotes the transformation of soluble Fe into secondary iron minerals is of great significance to the treatment of acid mine drainage (AMD). As a chemoautotrophic bacteria, A.ferrooxidans are vulnerable to hydraulic shock and loss. To ensure a higher Fe²⁺ oxidation and mineralization rate, immobilization method is often used to increase the bacterial density. In the study, schwertmannite, K-jarosite and NH₄-jarosite immobilized with A.ferrooxidans were synthesized under the same initial conditions (pH=2.30, Fe²⁺ concentration 4.48g/L, and A.ferrooxidans density 8×10⁶cells/mL). The he Fe²⁺ oxidation properties of A.ferrooxidans before (fixed state) and after (free state) minerals dissolution and the A.ferrooxidans fixing ability on minerals were compared. Results indicated that the dry weight of biosynthesis minerals was schwertmannite (0.24g) < NH₄-jarosite (0.35g) < K-jarosite (0.67g), however, A.ferrooxidans fixing ability was in the order of schwertmannite > NH₄-jarosite > K-jarosite. According to the Fe²⁺ oxidation rate of free A.ferrooxidans, calculated the effective biomass of A.ferrooxidans immobilized by schwertmannite, NH₄-jarosite and K-jarosite was 5.33×10⁷~5.33×10⁸, 5.72×10⁶~5.72×10⁷, and 6.35×10⁶cells/g (dry basis), respectively. The effective biomass of secondary iron minerals not only directly affects the oxidation rate of Fe²⁺, but also indirectly determines the mineralization removal effect of total Fe in AMD system.

Key words： A.ferrooxidans secondary iron minerals immobilization Fe²⁺ oxidation and mineralization properties
