摘　　要：针对挥发性有机废气的生物法净化过程 ,进行了吸附 生物膜新型理论的相关动力学模型研究 .经采用实验室数据和工业应用试验结果的对比验证表明 ,该模型对描述实际过程有很好的适用性 .应用该模型对入口气体甲苯浓度、气体流量及生物膜填料层高度等主要因素的影响进行模拟研究 ,模拟计算值与实验值之间有较好的相关性 ,相关系数r为 0 80～ 0For the process of biopurifying waste gas containing VOC in low concentration by using a biological trickling filter, the related kinetic model and simulation of the new Adsorption Biofilm theory were investigated in this study. By using the lab test data and the industrial test data, the results of contrast and validation indicated that the model had a good applicability for describing the practical bio purification process of VOC waste gas. In the simulation study for the affection of main factor, such as the concentration of toluene in inlet gas, the gas flow and the height of biofilm packing, a good pertinence was showed between calculated data and test dada, the interrelation coefficients were in 0 80～0 97.
