摘　　要：经对微生物进行适应性驯化培养,获得了在较高全铁质量浓度下具有较高催化氧化活性的菌株,当全铁质量浓度为80 kg/m3时,其平均催化氧化速率可达1.1 g/(L.h);基于反复分批式操作方法,将驯化获得的菌株用于生物聚合铁的制备,制得全铁质量浓度在0—100 g/L间的不同质量浓度的生物聚合铁溶液,并对其性质进行了分析。基于偏摩尔量理论,通过实验测定和理论推导,建立了硫酸亚铁加入量与生物聚合铁溶液体积的关系,从而可利用生物催化氧化技术制备出预定质量浓度的生物聚合铁,以满足不同用户对该产品的需求。The strains with obvious catalytic oxidizing activity at higher total-iron content were obtained on the basis of adaptability acclimation. When the total-iron mass concentration was 80 kg/m^3, average catalytic oxidizing velocity was up to 1.1 g/（ L · h ）. The different mass concentration bio-polymeric ferric sulfate solutions at the range of 0-100 g,/L were prepared with the strains based on repeated batch operation and their properties were analyzed. According to the theory of the partial molar quantity, experimental data was determined, then the relationship of the solute and the volume of solution was deduced. Based on the relationship, the solution of ferrous sulfate with expected mass concentration can be prepared for the different consumer＇s requirement by using biocatalytic oxidation technology.
