The cultivation of microalgae Chlorella pyrenoidosa (C. pyrenoidosa) using anaerobic digested starch wastewater (ADSW) and alcohol wastewater (AW) was evaluated in this study. Different proportions of mixed wastewater (AW/ADSW=0.176:1, 0.053:1, 0.026:1, v/v) and pure ADSW, AW were used for C. pyrenoidosa cultivation. The different proportions between ADSW and AW significantly influenced biomass growth, lipids production and pollutants removal. The best performance was achieved using mixed wastewater (AW/ADSW=0.053:1, v/v), leading to a maximal total biomass of 3.01±0.15 g/L (dry weight), lipids productivity of 127.71±6.31 mg/L/d and pollutants removal of COD=75.78±3.76%, TN=91.64±4.58% and TP=90.74±4.62%.
本研究评估了利用厌氧消化淀粉废水（ADSW）和酒精废水（AW）培养微藻蛋白核小球藻（C. pyrenoidosa）。使用不同比例的混合废水（AW/ADSW=0.176:1、0.053:1、0.026:1，v/v）和纯 ADSW、AW 进行 C. pyrenoidosa 培养。ADSW 和 AW 的不同比例显著影响生物量生长、脂质生产和污染物去除。使用混合废水（AW/ADSW=0.053:1，v/v）可获得最佳性能，最大总生物量为 3.01±0.15 g/L（干重），脂质产率为 127.71±6.31 mg/L/d，污染物去除率为 COD=75.78±3.76%、TN=91.64±4.58%和 TP=90.74±4.62%。
