摘　　要：传统除铁锰的方法是一级除铁、二级除锰。采用接触氧化—药剂氧化法,利用陶粒—锰砂双层滤料滤池可同时去除铁和锰,即通过一级曝气、药剂氧化和过滤即可同时去除铁和锰,简化了传统的二级曝气、过滤的长流程设计。除铁除锰滤料无需成熟期,无需除锰前处理,可直接生产应用。The conventional treatment technology for Fe^2＋ and Mn2. removal consists of 2-stages： Fe^2＋ removed in the 1st stage and Mn^2＋ removed in the 2nd stage. In this paper, Fe^2＋ and Mn^2＋ removed with a dual medial filter （upper layer loaded with ceramic particles and lower layer with manganese sand particles with KMnO4 addition and aeration） was introdued, ie contract oxidation and oxidant oxidation hold simultaneously in one-stage and after filtration Fe^2＋ and Mn^2＋ be removed to meet the requirement of drinking water quality.
