A lab-scale study of Scenedesmus obliquus: Acinetobacter pittii (S. obliquus: A. pitti) partnership cultured in synthetic domestic wastewater was conducted to evaluate the partnership performance for growth and removal of nutrients from wastewater. To draw out the functional dependencies of this partnership measured the ammonia-nitrogen (NH-N), ortho-phosphate (PO-P), soluble total phosphorus (TP), chemical oxygen demand (COD) and have got the nutrient removal rate of 85.90%, 91.50%, 73.75% and 100% respectively. The results showed that their optimized partnership ratio is 2:1 for S. obliquus: A. pitti and, CO & O exchanges in between was the more crucial parameters to shifting the best nutrient removals performance and promoted biomass quantity.
以斜生栅藻-不动杆菌（S. obliquus: A. pitti）共培养为对象，在实验室规模下，以人工模拟生活污水为处理对象，研究了共培养系统在去除污水中营养盐方面的性能。为了深入了解这种共培养系统的功能关系，我们对氨氮（NH-N）、正磷酸盐（PO-P）、总可溶性磷（TP）、化学需氧量（COD）等参数进行了测量，并得出了 85.90%、91.50%、73.75%和 100%的营养盐去除率。结果表明，在 S. obliquus: A. pitti 共培养中，最优化的配比为 2:1，并且 CO 和 O 的交换是影响最佳营养盐去除性能和促进生物量增长的更关键参数。
