摘　　要：在实验室条件下,提取人工挂膜启动后运行效果良好的除铁、锰和氨氮的BAF滤料上的混合菌,将其分离富集培养出铁锰菌和硝化菌,研究了铁锰菌、硝化菌和混合菌各自同步去除铁、锰和氨氮的效能。结果表明,铁锰菌不仅对铁和锰具有去除作用,对氨氮也有去除作用,且主要为亚硝化作用;硝化菌仅对氨氮有去除作用,对铁和锰则几乎无去除作用;混合菌同步去除铁、锰和氨氮的效果最好,铁锰菌和硝化菌共存对同步去除铁、锰和氨氮具有协同作用。Mixed bacteria for removal of iron, manganese and ammonia nitrogen were extracted inlaboratory from the ceramic media in a well-operated BAF after artificial biofilm formation. Iron and manganese oxidizing bacteria and nitrobacteria were separated and enriched from the mixed bacteria. The respective efficiencies of three types of bacteria for simuhaneous removal of iron, manganese and ammonia nitrogen were investigated. The results showed that iron and manganese oxidizing bacteria not only simultaneously removed iron and manganese, but also ammonia nitrogen via nitrosation. Nitrobacteria removed ammonia nitrogen, but not iron and manganese. Mixed bacteria showed the highest efficiency in simultaneous removal of iron, manganese and ammonia nitrogen. Iron and manganese oxidizing bacteria and nitrobacteria had a synergistic effect in simultaneous removal of iron, manganese and ammonia nitrogen.
