Coelastrella sp. QY01, a microalgae species isolated from a local pond, was identified and used for the treatment of anaerobically and aerobically treated swine wastewater (AnATSW). Microalgal growth characteristics, nutrient removal and lipid accumulation of QY01 cultivated in the initial concentration of AnATSW ranged from 63 to 319mg NH3-N/L were examined. The specific growth rate of QY01 cultivated in cultures ranged from 0.269 to 0.325day(-1) with a biomass productivity from 42.77 to 57.46mgL(-1)day(-1). Removal rates for NH3-N, TP and inorganic carbon in AnATSW at the various nutrient concentrations ranged from 90% to 100%, from 90% to 100% and from 74% to 78%, respectively. The lipid content of QY01 ranged from 22.4% to 24.8%. The lipid productivity was positive correlation with the biomass productivity. 40% AnATSW was optimal for QY01 cultivation, in which nutrient removal and productivity of biomass and lipid were maximized.
从当地池塘中分离出的微藻物种 Coelastrella sp. QY01 被鉴定出来并用于处理厌氧和好氧处理的猪废水（AnATSW）。研究了在初始浓度为 63 到 319mg NH3-N/L 的 AnATSW 中培养的 QY01 的微藻生长特性、养分去除和脂质积累。在培养物中培养的 QY01 的特定生长率在 0.269 到 0.325day(-1) 之间，生物量生产力在 42.77 到 57.46mgL(-1)day(-1) 之间。在不同营养浓度下，AnATSW 中 NH3-N、TP 和无机碳的去除率分别为 90%到 100%、90%到 100%和 74%到 78%。QY01 的脂质含量在 22.4%到 24.8%之间。脂质生产力与生物量生产力呈正相关。40%的 AnATSW 是 QY01 培养的最佳条件，在此条件下可以最大程度地去除养分并提高生物量和脂质的生产力。
