摘要(Abstract)：

为了研究不同磁感应强度对同步硝化反硝化(SND)工艺中脱氮机制及其对微生物群落和功能基因的影响，在SND工艺中施加不同磁感应强度的磁场，构建磁性序批式活性污泥反应器，研究不同磁感应强度作用下SND系统的脱氮效率及微生物多样性与群落结构的变化规律。结果表明，磁场作用有利于保持SND工艺的稳定性，并能提高反应器的氨氮负荷，使得氨氮去除率逐步趋近100.00%，总氮去除率也都稳定在75.00%以上，显著优于无磁场作用的工艺条件；磁场对微生物的种群结构有显著影响，经磁场作用的3组污泥样品中微生物的种群结构具有较高的相似性，其中磁感应强度为20 mT时样品中异氧硝化-好氧反硝化菌群的相对丰度较高，SND工艺脱氮效能相对较好。磁场作用通过提升代谢、细胞过程及遗传信息处理等功能基因的相对丰度来促进氮的去除。
