Biodegradation of mixture of VOCs in a biofilter
Abstract： Volatile organic compounds(VOC' s) in air have become major concem in recent years. Biodegradation of a mixture of ethanol and methanol vapor was evaluated in a laboratory biofilter with a bed of compost and polystyrene particles using an acclimated mixed culture. The continuous performance of the biofilter was studied with different proportion of ethanol and methanol at different initial concentration and flow rates. The result showed significant removal for both ethanol and methanol, which were composition dependent.The presence of either compound in the mixture inhibited the biodegradation of the other. 作 者： D.Arulneyam T.Swaminathan 作者單位： Biotechnology Research Centre, Department of Chemical Engineering, Indian Institute of Technology, Madras, Chennai 600 036, India 期 刊： 環境科學學報(英文版) ISTICSCI Journal： JOURNAL OF ENVIRONMENTAL SCIENCES 年，卷(期)： 2004, 16(1) 分類號： X701.7 Keywords： biofilter methanol ethanol elimination capacity upset loading VOCs biodegradation
