中文摘要：

选用生物陶粒和Hat Creek煤两种颗粒载体，应用于滴滤床颗粒填料生物反应器模型中，进行去除有机污染物的性能对比试验研究。研究表明，生物陶粒可作为滴滤床填料去除低浓度污水中的有机污染物，但在贫营养条件时，处理效果不如Hat Creek煤；而在进水浓度或水量增加，营养不成为限定因素的运行条件下，其极限负荷与处理效果明显要优于Hat Creek煤。

英文摘要：

The comparative study on the performance of organic pollutants removal was carried out using oarticle carder biotrickling filter. Bio-ceramics and High Creek Coal were used as two kinds of bio-carriers. The experimental results indicated that bio--ceramics are suited to be as can＇iers for trickling filter used for removing organic pollutants from lowconcentration wastewater. However, its treatment efficiency is lower than that of Hat Creek coal carriers in trickling filter in the running condition of poor nutrition. Comparatively, its limit load and treatment efficiency are obviously better than that of Hat Creek coal carriers in trickling filter when nutrition is not the limit factor of running condition as the increase of inlet concentration or inlet amount.
