Removal Characteristics of Nitrogen Oxides (NO x ) in Low Concentration using Peat-Mixed Media

摘要: In this study, removal characteristics of nitrogen oxides from road transport by using peat as the packing media for biodegradation have been investigated in long term. Physicochemical and biological treatment peatmixed eliminates any requirement to use chemical substances also facilitates biodegradable actions microorganism. Safe pollutants, no need apply additional microbes owing their active growth, generation secondary pollutants were found experiment. It was concluded that average efficiencies nitric oxide (NO) dioxide 80% 97% respectively with respect linear velocity 35~40 mm/s 0.3 ppm ozone concentration period operation. Inflow over 0.05 suitable when pretreated ozone. Non-ozone stage performed 20~100 then efficiency 38% 94% respectively. Other results showed apparent static pressure raised increases applied water content aerial mixed during fan
