摘      要：This paper is aimed at introducing our research result in the efficiencyin removing nitrous oxide gas (N_2O) by using compost as a medium filter,which is actually a kind of manure derived from cow faeces at KukusanKelurahan farm conlaing wood chips and some other microorganisms. Practicallyspeaking, N_2O is a major greenhouse gas, whose continuous presence in theatmosphere is expected to last over a 100 years and produce its radiative warmingeffect just next to CO_2. In spite of its rather small concentration in the atmosphere,it is the Number Four largest greenhouse gas contributor to the overallglobal warming, behind carbon dioxide, methane and water vapour. Thebiofiltration experiments we have conducted to explore its removing rate of N_2Ofrom flue gas help us to find various operating factors in the biofilter system. Sofar as we know, N_2O gas has been fed from the top of the column. It was flowingthrough the column when it is made to get circulated with a peristaltic pumpfor 6 hours. The data obtained in our paper prove to be in conformity with theLangmuir adsorption model. The highest N_2O gas removing efficiency can bemade to be as high as 70.22% at the highest biofilter length of 50 cm with thegas flowing rate of 200 mL/min. The results of this research have finally beenmodeled by the Langmuir adsorption isotherm formula with its K value obtainedbeing 16.949 L/mol.
