建立了一个多相混合模型，用于研究不同堆积类型下的光产氢和基质降解特性。在固定化细胞光生物反应器中填充了含有光合细菌(PSB)的凝胶颗粒，研究了有机负荷率(OLR)对光产氢和基质降解性能的影响。结果表明，数值模拟结果与文献报道的实验数据吻合较好，在产氢率和基质降解效率方面，文献报道的实验数据与数值模拟结果的相对偏差分别在−2.8%~+12.4%和−2.9%~+8.4%范围内。此外，还探讨了不同堆积方式下光生物反应器高度(H)和有机负荷(OLR)的影响。结果表明，OLR由7.2降至4.2，HPR由0.1升至0.2，HPR降低，但有利于提高SDE。此外，由于基质和产物传质量的增加，紧密堆积型可以改善光产氢和基质降解的性能。
A multiphase mixture model was developed for investigating the characteristics of photo-hydrogen production and substrate degradation under various stacking types. In this work, the entrapped-cell photobioreactor was packed with gel granules containing photosynthetic bacteria (PSB) and the effect of organic loading rate (OLR) on the performances of photo-hydrogen production and substrate degradation was studied. It was presented that the numerical simulation results were in good agreement with the reported experimental data, and the relative deviations between the reported experimental data and the numerical simulation results are within the range of −2.8 to +12.4% and −2.9 to +8.4% for the hydrogen production rate (HPR) and substrate degradation efficiency (SDE), respectively. Moreover, the effects of theOLRand the height of photobioreactor (H) under various stacking types were also explored. The results showed that the decrease of theOLRfrom 7.2 to 4.2 mmol/h and the increase of theHfrom 0.1 to 0.2 m led to the lowerHPR, but were beneficial to enhance theSDE. In addition, more closely stacking type can improve the performances of photo-hydrogen production and substrate degradation owing to the increased mass transfer amount of substrate and products.
