| 摘 要： | 近年来,在厌氧条件下,以Fe(Ⅲ)作为电子受体氧化氨氮的现象(Feammox)逐步受到研究者的关注.通过对由厌氧氨氧化(ANAMMOX)污泥驯化而来的Feammox污泥进行活性恢复,研究了pH值和温度对Feammox过程氮素转化的影响.结果表明,经过40 d运行,Feammox污泥活性获得恢复,环境中存在明显的氨氮转化和总氮去除,产物主要为硝酸盐和气态氮.亚硝酸盐一直处于2 mg·L~(-1)以下.pH值和温度对Feammox过程氮素转化的影响很大.Feammox过程pH值7和温度为30℃时,总氮去除量相对最高,去除率均达到50%以上.pH值为6.5时,氨氮的转化量最高为80.2%.Feammox反应过程中,铁离子的化合物沉淀及在污泥表面包裹是导致反应器持续运行和反应机制探索的主要干扰因素.
