Biofiltration of polluted gas streams containing malodorous triethylamine (TEA) was studied. The experiments were conducted in a laboratory-scale reactor with a mixture of sieved compost and chaff particles as the filter material on which the microorganisms were immobilized. The concentrations of TEA in the inlet gas varied from 0.32 to 3.45 g/m (78 ppmv to 841 ppmv), while the superficial velocity of the inlet gas ranged from 60.1 to 322.2 m/hr. The removal efficiency of triethylamine in the biofilter decreased as the gas velocity or TEA concentration in the inlet gas increased. Moreover, the elimination capacity of this biofilter could reach up to 140 g/(m hr). When the loading of TEA exceeded this critical value, substrate inhibition occurred and the elimination capacity decreased. A mathematical model predicting the removal efficiency of the pollutant was also developed in this study. The inhibitory effect of the substrate on the growth rate of the biomass was considered in this model. The proposed model could accurately represent the experimental data obtained in this study.
对含有恶臭三乙胺（TEA）的污染气流进行生物过滤研究。实验在实验室规模的反应器中进行，使用筛分堆肥和谷壳颗粒的混合物作为固定微生物的过滤材料。进气中TEA的浓度在0.32至3.45 g/m（78 ppmv至841 ppmv）之间变化，而进气的表观速度在60.1至322.2 m/hr之间。生物滤池中三乙胺的去除效率随着气体流速或进气中TEA浓度的增加而降低。此外，该生物滤池的去除能力可达140 g/(m³·hr)。当TEA负荷超过此临界值时，会发生底物抑制，去除能力下降。本研究还建立了一个预测污染物去除效率的数学模型。该模型考虑了底物对生物质生长速率的抑制作用。所提出的模型能够准确地反映本研究中获得的实验数据。
