摘　　要：　在pH中性条件下生物接触滤层中Mn2+的氧化是生物氧化,滤层中以除锰菌为核心的生物群系的平衡与稳定是除锰活性的基础。生物滤层不但可以同时氧化去除Fe2+、Mn2+,而且对进入滤层前已氧化成Fe3+的微细颗粒也有良好的截留作用。以此生物固锰除锰机制为基础开发了弱曝气、一级过滤的生物除铁除锰简缩流程,确定了相应的设计与运行参数并指导了沈阳市开发区生物除铁除锰水厂的设计与运行。投产一年多来出水水质良好,总铁为痕量,锰<0.05mg/L。Manganese (Mn2+) oxidation in contact filter layer under neutral pH condition is the biological oxidation, the balance and stability of biome with Mn2+ removal organism as center in filter layer is the basis of Mn2+ removal activity. The bio-filter can not only result in the simultaneous removal of Fe2+ and Mn2+, but also effectively capture the fine particles that have been oxidated to Fe3+ before entering the filter layer. Based on the mechanism of biological Mn2+　fixation and removal, simple process of weak aeration and primary filtering has been developed for biological Fe2+ and Mn2+ removal, the related design and operating parameters have been determined, and instruction has been given to the design and operation of water treatment plant with Fe2+ and Mn2+removal in Shenyang Development Area. Since the plant was put into operation for one more year, it has achieved good effluent quality with trace amount of total iron and Mn2+ < 0.05 mg/L.
