A 4m pilot-scale baffled continuous-flow photoreactor with four sequential chambers (#1-#4) was established and tested to evaluate its photo-fermentative hydrogen production from wastewater that contains (10g/L glucose using a functional consortium at 30°C, under light with an intensity of 3000±200lux with a hydraulic retention time (HRT) of 24-72h. The hydrogen production rate and the broth characteristics varied significantly in the flow direction. The hydrogen production rate was highest in chamber #1, and lower in chambers #2-#4 at an HRT of 72h, while the peak production rate shifted to the latter chambers as the HRT was shortened. The overall H production rate increased as HRT decreased, but was not consistent with the predictions that were based on the complete-mixing assumption.
建立并测试了一个 4 米长的带有四个连续腔室（#1-#4）的中试规模挡板连续流光反应器，以评估其利用含有（10g/L 葡萄糖的废水）在 30°C 下、光照强度为 3000±200lux 条件下、水力停留时间（HRT）为 24-72h 时利用功能菌群进行的光发酵产氢性能。在流动方向上，氢气的产率和发酵液特性有显著差异。在 HRT 为 72h 时，氢气的产率在腔室#1 中最高，在腔室#2-#4 中较低，而当 HRT 缩短时，产率峰值转移到后面的腔室。随着 HRT 的降低，整体氢气产率增加，但与基于完全混合假设的预测并不一致。
