摘　　要：通过中试试验,探讨了在春季温度较低的情况下,不同滤料介质的生物滤池对于姚江微污染水源水的处理效果。研究表明,双层生物滤料滤池能够有效地去除浊度、有机物、氨氮等污染物质,适合于传统滤池的改造。采用颗粒活性炭-石英砂滤料滤池的综合处理效果优于同类型的沸石-石英砂滤料滤池,通过加入一定量的臭氧(1.50 mg/L)可以进一步提高生物滤池的处理效果。　The effect of biofilters with different filter media on treatment of Yao-jiang slightly-polluted water in spring lower temperature was discussed through the pilot-scale experiment.The results showed that,dual-media biofilter could effectively remove the turbidity,organic matters,ammonia nitrogen and some other pollutants,which is fit for the traditional filter modification.The comprehensive treatment effect of the slightly-polluted water by the filter with granular actived carbon-quartz sand as filter media was superior to that by the filter with zeolite-quartz sand as filter media,and the treatment effect could be further improved by adding certain amount of ozone（1.50 mg/L）.
