| 摘 要： | 迄今为止的除铁、除锰工艺大多是采用传统的处理方法，即：一级除铁、二级除锰。在生物固锰、除锰技术确立之后，通过长期的试验研究，发现了铁、锰离子可以在同一生物滤层中去除的规律，从而可以采用一级曝气、过滤的简缩流程以更新传统的二级曝气、过滤的长流程设计。

| Abstract: | The conventional treatment technology has been used so far for Fe 2+ and Mn 2+ removal process, that is: Fe 2+ removal is achieved in the 1st stage and Mn 2+ removal in the 2nd stage. After the development of biological fixation and removal of Mn 2+, we have made experiments for a long time and found the regularity that Fe 2+ and Mn 2+ can be removed in the same biological filtering layer. Thus, a simple process of one-stage aeration and filtration may be used for renewal of the conventional two-stage aeration and filtration process. |
