The comparative study on the performance of organic pollutants removal was carried out using oarticle carrier 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 carriers for trickling filter used for removing organic pollutants from low- concentration 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.
