Scale-up potential of cultivating Chlorella zofingiensis in piggery wastewater for simultaneous wastewater treatment and biodiesel production was tested. The cultivation of C. zofingiensis with autoclaved wastewater and NaClO-pretreated wastewater, cultivation of algae indoors and outdoors, and stability of semi-continuous feeding operation were examined. The results showed that C. zofingiensis cultivated in piggery wastewater pretreated by autoclaving and NaClO had no evident difference in the performance of nutrient removal, algal growth and biodiesel production. The outdoor cultivation experiments indicated that C. zofingiensis was able to adapt and grow well outdoors. The semi-continuous feeding operation by replacing 50% of algae culture with fresh wastewater every 1.5 days could provide a stable net biomass productivity of 1.314 g L(-1) day(-1). These findings in this study can prove that it is greatly possible to amplify the cultivation of C. zofingiensis in piggery wastewater for nutrient removal and biodiesel production.
研究了在猪场废水中培养栅藻（Chlorella zofingiensis）以实现同时进行废水处理和生物柴油生产的放大潜力。考察了用高压灭菌和 NaClO 预处理废水培养 C. zofingiensis、室内和室外培养藻类以及半连续进料操作的稳定性。结果表明，用高压灭菌和 NaClO 预处理的猪场废水培养的 C. zofingiensis 在去除营养物、藻类生长和生物柴油生产方面的性能没有明显差异。室外培养实验表明，C. zofingiensis 能够很好地适应和在室外生长。每 1.5 天用 50%的新鲜废水代替藻类培养物进行半连续进料操作，可以提供稳定的净生物质生产率为 1.314 g L(-1) day(-1)。本研究中的这些发现可以证明，在猪场废水中大量培养 C. zofingiensis 以去除营养物和生产生物柴油是非常可行的。
