摘　　要：通过实验室模型试验,对比研究了不同滤料的曝气生物滤池处理有机废水的效能,两组装置对废水CODcr及色度的去除率均达到40%以上。分析了曝气生物滤池脱色机理及需要注意的滤料板结问题,提出了以陶粒和海绵铁混合滤料为佳的结论。Based on the lab experiment and the contrastive study of the efficiency of treating wastewater by biofiltration with different filter materials, the results show that the removal rate of CODcr and color is more than 40 percent. The paper analyses the decolorizing mechanism of biofiltration and the hardening of filter materials and finally concludes that the mixed argil grain and spongy iron is the best.
