摘　　要：采用生物滤柱净化高铁、高锰、高氨氮地下水,考察了生物净化效果及影响因素。结果表明,在设计滤速为5 m/h,试验用地下水的Fe2+、Mn2+和NH4+-N分别为15、1.5和1.2 mg/L的条件下,生物滤柱对其净化效果良好,但所需滤层较厚(为1.5 m),出水的Fe2+、Mn2+和氨氮分别可降至0.13、0.05和0.26 mg/L;在生物滤柱中,Fe2+的高效去除空间为最上部,NH4+-N的为中、上部,Mn2+的为中、下部;溶解氧为影响生物滤层除锰的关键因素。The biological filtration column was used to purify groundwater with high-concentration Fe, Mn and NH^＋4 -N, and the purification efficiency and the influence factors were investigated. When the design filtration velocity is 5 m/h, and Fe^2＋ , Mn^2＋ and NH^＋4 - N in the experimental groundwater are 15mg/L, 1.5 mg/L and 1.2mg/L, the biological filtration column has good purification efficiency, but a thicker filtration layer is 1.5 m. The Fe^2＋ , Mn^2＋ and NH^＋4 - N can be reduced to 0.13mg/L, 0.05 mg/L and 0.26 mg/L respectively. The uppermost part of biological filtration column is effective for removal of Fe^2＋ , the upper and the middle parts are for NH^＋4 - N, the middle and the lower parts are for Mn^2＋. Dissolved oxygen is a main influence factor in the biological removal of manganese.
