摘要
对生物强化法烟气同时脱硫脱氮的动力学进行探讨研究,结果表明:生物强化前后,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,对生物强化前后NO_X的出口气体浓度、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0.95~0.99)。
The study on kinetics of simultaneous desulfurization and denitrification from flue gas by bioaugmentation was conducted. The results indicated that the biodegradation reactions of SO2 and NOxin the biofilm were first-order reactions and fast biodegradation reactions before and after bioaugmentation. The simulation research results 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 bioaugmentation indicated that there were good relativities between simulated theoretical data and experimental data by applying this theory and its kinetic model(the interrelation coefficients were in the range of 0. 95 ~ 0. 99).
