摘　　要：由于不同地区的地下水中总铁浓度差别很大,考察了进水总铁升高对生物滤柱中锰、氨氮去除效果的影响。研究结果表明:当进水总铁约1 mg/L,锰、氨氮分别约2、1.3 mg/L时,铁、锰、氨氮均有很好的去除效果,出水总铁、锰、氨氮分别为0.077、0.041、0.032 mg/L;当进水总铁升高到约5、10 mg/L时,锰、氨氮的去除效果受到明显影响,但在稳定阶段,锰、氨氮又降到了国家标准以下。沿程分析发现,铁、氨氮均从滤层顶部开始去除,当二价铁全部氧化后锰开始去除;随着进水总铁的升高,锰、氨氮的去除区域均明显向下延伸。Due to the concentration of total iron in groundwater varies greatly in different areas, the influence of total iron in influent on the removal efficiency of manganese and ammonia in biofilter was investigated. The results showed that when total iron was about 1 mg/L, and manganese and ammonia were about 2 mg/L and 1.3 mg/L, respectively, an excellent performance for iron, manganese and ammonia removal was achieved. Total iron, manganese and ammonia in effluent were 0.077, 0.041, 0.032 mg/L, respectively. When total iron increased to about 5 mg/L and 10 mg/L, the removal efficiency of manganese and ammonia was obviously affected, but at the stable stage, manganese and ammonia were below the national standard. It was found that iron and ammonia were removed from the top of the filter layer, and manganese was removed after ferrous iron was completely oxidized. With the increase of total iron in the influent, the removal areas of manganese and ammonia extended downward.
