摘　　要：采用生物氧化过滤的方法对地下水除铁进行了研究。探讨了滤柱生物除铁的影响机理。在进水Fe2+的质量浓度为4.3mg/L,pH值为6.4～6.6,水温为23～25℃,溶解氧的质量浓度为1.5mg/L,滤速为8m/h的条件下出水水质良好,出水Fe2+的质量浓度达到0.1mg/L以下。通过灭活试验和细菌计数等试验验证该滤柱在除铁中,生物氧化起主要作用。Iron-removal from ground water by biological oxidation filtration was studied. The influencing mechanism of the filter candle on biological iron-removal was discussed. Under the condition that the mass concentration of Fe^2＋ was 4.3 mg/L, the pH value of the raw water was 6.4 - 6.6, the water temperature was 23 - 25℃, the mass concentration of dissolved oxygen was 1.5 mg/L, the filter speed was 8 m/h, a good effluent quality was obtained, the mass concentration of Fe^2＋ in effluent water was below 0.1 mg/L. The inactivation experiment, bacteria counting experiment and some other experiments indicated that biological oxidation had a significant effect on ironremoval in the said filter candle.
