In this study, a novel internally illuminated mirror photobioreactor (IIM-PBR) was designed to improve microalgae biomass production through providing a homogenous light distribution in cultivation medium. The performance of the IIM-PBR was compared with internally illuminated control photobioreactor (IIC-PBR) and externally illuminated control photobioreactor (EIC-PBR) in terms of cell growth, wastewater treatment and bioproducts generation. Compared with the IIC-PBR and EIC-PBR, the IIM-PBR increased microalgae growth rate up to 60 % and 30%, respectively. Municipal wastewater treatment revealed that the IIM-PBR could significantly improve nutrients removal as the final removal efficiencies of 90%, 95% and 90% were obtained for nitrate, phosphate and COD, respectively. Moreover, the IIM-PBR increased the total bioproducts production by 89% and 46% compared to in the IIC-PBR and EIC-PBR, respectively. Based on the energy consumption calculation, the mirror's light-reflective properties of the IIM-PBR resulted in a significant reduction of total energy consumption (∼10 times).
在这项研究中，设计了一种新型内部照明反射镜光生物反应器（IIM-PBR），通过在培养介质中提供均匀的光分布来提高微藻生物质的产量。从细胞生长、废水处理和生物产物生成三个方面，比较了 IIM-PBR 与内部照明对照光生物反应器（IIC-PBR）和外部照明对照光生物反应器（EIC-PBR）的性能。与 IIC-PBR 和 EIC-PBR 相比，IIM-PBR 分别将微藻生长速率提高了 60%和 30%。城市废水处理表明，IIM-PBR 可以显著提高营养物质的去除率，最终的硝酸盐、磷酸盐和 COD 的去除效率分别达到 90%、95%和 90%。此外，与 IIC-PBR 和 EIC-PBR 相比，IIM-PBR 分别使总生物产物的产量增加了 89%和 46%。基于能耗计算，IIM-PBR 中镜子的光反射特性导致总能耗显著降低（约 10 倍）。
