Ammonium removal from artificial wastewater by microalgal-bacterial consortia in a flat-panel reactor (FPR1) was compared with a microalgae-only flat-panel reactor (FPR2). The microalgal-bacterial consortia removed ammonium at higher rates (100±18mgNH-NLd) than the microalgae (44±16mgNH-NLd), after the system achieved a stable performance at a 2days hydraulic retention time. Nitrifiers present in the microalgae-bacteria consortia increased the ammonium removal: the ammonium removal rate by nitrifiers and by algae in FPR1 was, respectively, 50(±18) and 49(±22)mgNH-NLd. Apparently ammonium removal by algae was not significantly different between FPR1 and FPR2. The activity of the nitrifiers did not negatively affect the nitrogen uptake by algae, but improved the total ammonium removal rate of FPR1.
在平板式反应器（FPR1）中，通过微藻-细菌共生体去除人工废水中的铵与仅用微藻的平板式反应器（FPR2）进行了比较。在水力停留时间为 2 天时，系统达到稳定性能后，微藻-细菌共生体的铵去除率（100±18mgNH-NLd）高于微藻（44±16mgNH-NLd）。共生体中存在的硝化菌提高了铵的去除率：FPR1 中硝化菌和藻类的铵去除率分别为 50（±18）和 49（±22）mgNH-NLd。显然，藻类对铵的去除率在 FPR1 和 FPR2 之间没有显著差异。硝化菌的活性并没有对藻类的氮吸收产生负面影响，反而提高了 FPR1 的总铵去除率。
