摘　　要：传统的污水处理工艺大都采用活性污泥法,虽然对污水净化发挥了重要作用,但处理后的出水中依然残留部分有机物、氮、磷等污染物。本研究以污水处理厂出水为莱茵衣藻培养基,探讨莱茵衣藻在污水中的生长情况及对污水中营养元素(氮、磷)的去除效果。研究结果表明,莱茵衣藻在污水中的生长状态良好且对污水中总磷、总氮和 COD 具有较好的处理效果,去除率分别达到了 98.7%、72.6%和 81.5%。本研究为污水处理及微藻培养技术的改进提供了新的理论依据。The traditional waste water treatment process, such as activated sludge process, plays an important role in the purification of waste water. However, there are still some residual contaminants like organic matters, nitrogen and phosphorus in the outlet of waste water treatment plants. Thus, the main aim of the present study was to investigate the feasibility of the treated waste water as the cultural medium for cultivating Chlamydomonas reinhardtii culturation. The growth of C. reinhardtii in treated sewage was investigated by match assays, and the removal capacity of C. reinhardtii for nutrient elements (nitrogen and phosphorus) in sewage was also studied. the results showed that C. reinhardtii could grow in good condition in the treated sewage. Meanwhile, C. reinhardtii exhibited a high removal capacity for contaminants in sewage, with a high removal ratio of 98.7%, 72.6%, and 81.5% for TP, TN, and COD. This study provides a new theoretical basis for the improvement of waste water treatment and microalgae culture.
