Real field demonstrations to assess the removal efficiency of nutrients and organic matter from domestic wastewater were carried out using algal-bacterial photobioreactors. The reactors which consisted of three basins of 200 L were fed with secondary effluent of domestic wastewater and operated under natural day light/dark cycles. The results demonstrated that reaction time (RT) has a substantial role on the whole process performance. Whereas inoculation with nitrifiers affected the process only in some aspects. The enhancement in the dissolved oxygen production rate (1.15 mg O₂. L⁻¹.h⁻¹) was in alignment with growing higher algal biomass concentrations due to the increase in RT. COD removal rates were significantly increased (p < 0.05) with increasing the RT, and removal rates of 27%, 46% and 50% were obtained under RTs of 2, 3 and 4hrs. respectively. Meanwhile, 30%, 84% and 95% of the phosphorus was removed under the same studied RTs. No significant effect was recorded due to the addition of nitrifying bacteria on the removal of both COD and phosphorus. Ammonium (NH₄⁺-N) removal rates were also increased with increasing RT and by the addition of nitrifiers, such that removal rates of 13%, 21% and 31% were obtained in basins inoculated with nitrifiers, but 11%, 14% and 19.5% were obtained in non-inoculated basins under RT of 2, 3, and 4 hrs. respectively. These results provide some new insights into algal-bacterial symbiosis systems under real field conditions which could be helpful for further process development.

使用藻类细菌光生物反应器进行了现场演示，以评估从生活废水中去除营养和有机物的效率。将由三个200 L的水盆组成的反应器喂入生活污水的次级污水，并在自然光/暗周期下运行。结果表明，反应时间（RT）对整个过程的性能具有重要作用。而硝化剂的接种仅在某些方面影响该过程。在溶解氧生产速率的提高（1.15毫克邻₂：L ^-1 ·H ^-1）与RT的增加所导致的藻类生物质浓度的增加相一致。随着RT的增加，COD去除率显着提高（p <0.05），在2、3和4小时的RT下，去除率分别为27％，46％和50％。分别。同时，在相同的研究条件下，分别去除了30％，84％和95％的磷。由于添加硝化细菌对COD和磷的去除没有明显影响。铵（NH ₄ ⁺-N）的去除率也随着RT的增加和硝化器的添加而增加，因此在接种硝化器的水池中去除率分别为13％，21％和31％，但分别为11％，14％和19.5％。在2小时，3小时和4小时的RT下未接种的盆中。分别。这些结果为在真实条件下的藻-细菌共生系统提供了一些新见解，这可能有助于进一步的工艺开发。
