中文摘要：
本文以填料床光生物制氢技术为背景，采用格子Boltzmann传质模型对有机废水绕流表面附着光合生物膜的固体颗粒的三维流动及其表面生化反应和传输过程进行研究，计算分析了进口流速及光照强度对传质过程及产氢性能的影响。结果表明：进口流速的增加降低了底物降解效率；随着光强增加底物降解效率先增大后减小，并在光强I0=6000lx时达到最大。
英文摘要：
3D lattice Boltzmann mass transfer model is adopted to simulate hydrodynamics and mass transfer accompanying with biochemical reaction for organic wastewater around a granule covering with photosynthetic bacteria biofilm, which is the scenario of the photo-biohydrogen production in packed bed reactor. The effects of influent solution velocity and illumination intensity on mass transfer and hydrogen production performance are investigated. The numerical solutions indicate that the substrate consumption efficiency decreases with increasing influent velocity; the substrate consumption efficiency increases with increasing illumination intensity and reaches a maximum value atⅠ0=6000lx, and then it drops down once further increases.
