| 摘 要： | 为模拟微生物浸铀过程中各组分的动态变化,通过将微生物浸铀动力学过程的3个反应和4个方程嵌入PHREEQC地球化学数据库拟合试验结果。结果表明:建立的基于PHREEQC软件的微生物浸铀动力学数据库能够模拟微生物浸铀的化学反应动力学过程,模拟结果分析发现,铀的浸出既受溶液中铁离子浓度的直接影响,又受微生物数量和亚铁离子浓度及氧化的间接影响。

| Abstract: | In order to simulate dynamic change of various components during uranium bioleaching, three reactions and four equations of microbial immersion uranium dynamics were embedded in PHREEQC geochemical database to fit experimental results. The results show that microbial immersion uranium dynamics database based on PHREEQC software can simulate chemical reaction kinetics of uranium bioleaching. The simulation results show that leaching of uranium is directly affected by concentration of iron ions in solution, and indirectly affected by number of microorganisms and concentration and oxidation of ferrous ions. |
