Four common used microalgae species were compared in terms of settleability, nutrient removal capacity and biomass productivity. After 1 month training, except cyanobacteria Phormidium sp., three green microalgae species, Chlamydomonas reinhardtii, Chlorella vulgaris and Scenedesmus rubescens, showed good settleability. The N and P removal efficiency was all above 99% within 7, 4, 6 and 6 days for N and 4, 2, 3 and 4 days for P, resulting in the N removal rates of 3.66±0.17, 6.39±0.20, 4.39±0.06 and 4.31±0.18 mg N/l/d and P removal rates of 0.56±0.07, 0.89±0.05, 0.76±0.09 and 0.60±0.05 mg P/l/d for Phormidium sp., C. reinhardtii, C. vulgaris and S. rubescens, respectively. Phormidium sp. had the lowest algal biomass productivity (2.71±0.7 g/m(2)/d) and the other three green microalgae showed higher algal biomass productivity (around 6 g/m(2)/d). Assimilation into biomass was the main removal mechanism for N and P.
比较了四种常用的微藻物种在沉降性能、养分去除能力和生物量生产力方面的差异。经过 1 个月的培养，除蓝藻 Phormidium sp.外，三种绿藻小球藻（Chlamydomonas reinhardtii）、普通小球藻（Chlorella vulgaris）和栅藻（Scenedesmus rubescens）均具有良好的沉降性能。N 和 P 的去除效率在 7、4、6 和 6 天内分别达到 99%以上，在 4、2、3 和 4 天内分别达到 99%以上，导致 N 的去除率分别为 3.66±0.17、6.39±0.20、4.39±0.06 和 4.31±0.18mgN/l/d，P 的去除率分别为 0.56±0.07、0.89±0.05、0.76±0.09 和 0.60±0.05mgP/l/d，Phormidium sp.的生物量生产力最低（2.71±0.7g/m(2)/d），其他三种绿藻的生物量生产力较高（约 6g/m(2)/d）。同化到生物量是去除 N 和 P 的主要机制。
