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(huán)境科學(xué)學(xué)報(bào)(英文版)  ISTICSCI   Journal： JOURNAL OF ENVIRONMENTAL SCIENCES  年，卷(期)： 2004, 16(1)  分類號(hào)： X701.7  Keywords： biofilter    methanol    ethanol    elimination capacity    upset loading    VOCs    biodegradation
