The sulfate reducing bacteria tends to adhere on to the surface obtains 1) super hydrophobicity; 2) macro pores whose average diameter is 1~5 times larger than the bacteria’s scale; 3) iron element. Based on these, a magnetic macroporous polymer beads were prepared and applied as biofilm support. The oleic modified Fe3O4 particles and the magnetic porous polymer were characterized by TGA, and the actual content of Fe3O4 could be calculated from file “TGA.opj”. The saturate magnetizations of the Fe3O4 particles, magnetic polymer before and after biofilm loading were characterized by VSM, and the data named "VSM.opj" The morphology of the polymer sphere was characterized by SEM, as shown in the article. The biofilm loading and the desulfurization performances of three bio-supports at the start-up stage and the long-term cultivation were evaluated, and the raw data has been listed as “starting stage.opj” and ”Fe-desulfurization rate.opj”,respectively.

硫酸盐还原菌（sulfate reducing bacteria）附着于该类表面后，可获得以下特性：1）超疏水性；2）平均孔径为菌体尺寸1~5倍的大孔；3）铁元素。基于上述特性，研究人员制备了磁性大孔聚合物微球，并将其用作生物膜载体。采用热重分析法（TGA）对油酸改性Fe3O4颗粒及磁性多孔聚合物进行了表征，Fe3O4的实际含量可通过文件"TGA.opj"计算得到。采用振动样品磁强计（VSM）对Fe3O4颗粒、成膜前及成膜后的磁性聚合物的饱和磁化强度进行了表征，相关数据存储于"VSM.opj"文件中。聚合物微球的形貌通过扫描电子显微镜（SEM）进行了表征，具体结果见本文。评估了三种生物载体在启动阶段与长期培养过程中的生物膜负载性能及脱硫性能，原始数据分别列于"starting stage.opj"与"Fe-desulfurization rate.opj"文件中。
