摘　　要：东北地区的地下水大都存在铁锰等金属超标的情况。采用生物滤层接种混合细菌法,探究了启动周期对石英砂滤料和混层滤料除铁锰效果的影响。结果表明:接种混合细菌的石英砂滤料和混层滤料对含铁锰地下水均有较好的处理效果。石英砂滤料对锰的去除率为97. 00%,滤层的成熟期为47 d;混层滤料对锰的去除率为97. 99%,滤层的成熟期为35 d;两种滤料均能在较短的成熟期内达到良好的铁去除效果。Most of the groundwater in the Northeastern region contains iron, manganese and other metals exceeding the standards. The biological filter layer inoculated the mixed bacteria method was used to and the influence of the start-up period on the removal of iron and manganese from the quartz sand filter material and the mixed filter media was investigated. The results showed that the manganese removal rate of the quartz sand filter material reached 97.00%, the maturity of the filter layer was 47 days;the manganese removal rate of the mixed layer filter material was 97.99%, and the maturity of the filter layer was 35 days. Both of the filter media could achieve good iron removal in a shorter maturity period. It was indicated that the quartz sand and the mixed layer filter material inoculated with mixed bacteria could achieve better treatment effect of the groundwater containing iron and manganese.
