摘　　要：对化学强化法提高生物膜填料塔同时脱硫脱氮性能的净化过程,及其动力学进行探讨研究。结果表明:化学刺激作用在化学强化系统中发挥重要作用,化学强化前后,生物膜中的SO_2、NO_x的生化降解反应均为一级反应,且SO_2、NO_x在生物膜中的生化降解反应均为快速生化反应;依据吸附-生物膜理论及其动力学模型,对化学强化前后NO_x的出口浓度、生化去除量及净化效率进行模拟及对比验证表明,利用该理论建立的动力学模型模拟的理论值与实验值之间均具有较好的相关性(相关系数在0.86~0.99)。The study on the purification process and kinetics of simultaneous desulfurization and denitrification by biofilmpacking tower by chemical strengthening method was conducted. The results indicated that chemical stimulation played an important role in the chemical strengthening system,and the biodegradation reactions of SO2 and NOx in the biofilm were firstorder reactions and fast biodegradation reactions before and after chemical intensifying. The results of simulation research and contrast verifications,for simulating the concentration in outlet,bio-elimination capacity and purification efficiency,by applying the adsorption-biofilm theory and its kinetic model before and after chemical intensifying,indicated that there were good relativities between simulated theoretical data and experimental data,with the interrelation coefficicients in the range of 0. 86 ~ 0. 99.
