摘　　要：目的研究对含铁、锰地下水的处理.方法采用曝气-接触氧化过滤工艺,分别处理模拟含铁、锰的水,含铁、锰、氨氮的水,含铁、锰、氨氮和有机物的水(复合型微污染水).结果有机物、氨氮污染物与铁、锰共存时,对地下水中铁、锰的氧化去除具有较大的阻碍作用,接触过滤除铁、除锰效果下降,有机物和氨氮过滤去除效果也较差;氨氮污染物与铁、锰共存时,氨氮质量浓度在6.65 mg/L以下对铁的氧化影响不大,但对锰的去除有影响;铁、锰、有机物、氨氮共存时,在接触氧化滤层中可形成生物氧化有机物及氨氮的作用机制.结论有机物与氨氮污染对含铁、锰地下水接触氧化过滤效果的影响较大.The paper aims to study the treatment technology of groundwater containing iron and manganese with pollutants of ammonium and organics in drinking water.There are three kinds of test water samples in study：（1）the water containing iron and manganese;（2）the water containing iron,manganese and ammonium;（3）the water containing iron,manganese,ammonium and organics（multi-polluted groundwater）.Each sample was treated by aeration then contacted oxidation filter.The test results indicted that removal rate of iron and manganese was very low from the sample（3）.Therefore oxidation of iron and manganese was impeded greatly if ammonium and organics existed in water.The influence of removal iron from（2）,in which ammonium concentration was below 6.65 milligram per liters,was light,but the influence of manganese removal was great.When in the sample（3）,iron,manganese and ammonium coexist in groundwater the biodegradable mechanism in the contact oxidation filter could establish gradually.In conclusion,for drinking water,the effect of groundwater polluted with ammonium and organics on treatment of contact oxidation filter is great.
