  • 摘要: 为了提高固定化微生物凝胶球的性能，实验研究了在凝胶球中添加无机材料粉末活性炭、SiO2、CaCO3和人造沸石，并从固定化微生物凝胶球的生物活性、机械强度、微观结构和溶出性多方面考核，比较不同无机材料对凝胶球性能的影响。研究结果表明，添加CaCO3能明显提高凝胶球的传质性能，进而提高凝胶球对氨氮的处理效果，添加人造沸石能提高凝胶球的抗拉强度，添加SiO2能提高凝胶球的密度，添加粉末活性炭能提高凝胶球的压缩强度。
    Abstract: A variety of inorganic materials, such as powdered activated carbon, SiO2, CaCO3 and artificial zeolite, were added into immobilized microorganism gel beads, in order to improve their properties. Evaluating from biological activity, mechanical strength, microstructure and solubility together, the effects of inorganic materials on properties of immobilized microorganism gel beads were studied. The results show that CaCO3 can significantly improve the mass transfer performance, and then improve the removal efficiency of ammonia nitrogen, artificial zeolite can enhance the tensile strength of gel beads, while SiO2 can increase the density of gel beads, whereas powdered activated carbon can improve the compression strength of gel beads.
