The filter medium was composed of composts and wood chips, and the wastewater containing denitrifying bacteria was blended into it. So the microorganisms can grow on the surface of filter medium to reduce NO by microbial denitrification. The gas inlet concentration of NO, oxygen level, additional carbon source, and phosphates that would influence the NO elimination rate of the biofilter were discussed in this study. The results indicate that raising the inlet concentration of NO and the oxygen level decrease the NO removal. However, adding glucose and phosphates increase it. In anaerobic condition, the gas flow rate was maintained at 500 ml/min and the NO inlet concentration was 500 ppm, the NO elimination rate was up to a highest value about 99% when adding glucose 1 g/day and phosphates at the same time. The oxygen level larger than 2% will inhibit the microbial denitrification and the NO elimination rate decreased into 60%. After adding the glucose 1 g/day, the filter effect increased from 21% into 99%, and it also changed from 54% into 72% by adding the phosphates. Moreover, the anaerobic experiment was simulated using reaction limitation model. Under the condition of a fixed flow rate, the NO elimination rate decreased when NO inlet concentration increased in the zero order reaction limitation model, but it was a constant in the first order reaction limitation model. The trend of anaerobic experiment can be well simulated using this model.application/pdf333548 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所自動連續監測生物濾床一氧化氮反應限制biofilterauto-continuous monitoringnitric oxidereaction limitationreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22016/1/872218E002009.pdf
