研究了生活废水中培养的小球藻的营养物去除效率，以及在废水处理过程中使用膜过滤作为预处理工具的潜力。小球藻在采用两种不同废水处理的泡罩塔系统中分批培养 12 天。 0.2 μm 膜过滤的初级废水中最大吸收量为 94.18% 铵 (NH4-N) 和 97.69% 正磷酸盐 (PO4-P)。膜过滤通过去除细菌、原生动物、胶体颗粒和悬浮固体来增强普通念珠菌的养分吸收性能，从而提高光合作用的光利用率。这项研究的结果表明，在营养丰富的膜过滤废水中生长普通念珠菌为生活废水处理提供了一种选择，以提高最终出水的质量。
The nutrient removal efficiency of Chlorella vulgaris cultivated in domestic wastewater was investigated, along with the potential to use membrane filtration as a pre-treatment tool during the wastewater treatment process. Chlorella vulgaris was batch cultivated for 12 days in a bubble column system with two different wastewater treatments. Maximum uptake of 94.18% ammonium (NH4-N) and 97.69% ortho-phosphate (PO4-P) occurred in 0.2 μm membrane filtered primary wastewater. Membrane filtration enhanced the nutrient uptake performance of C. vulgaris by removing bacteria, protozoa, colloidal particles and suspended solids, thereby improving light availability for photosynthesis. The results of this study suggest that growing C. vulgaris in nutrient rich membrane filtered wastewater provides an option for domestic wastewater treatment to improve the quality of the final effluent.
