Wastewater rich in organic carbon, nitrogen and phosphorus may serve as a convenient source of carbon and nutrients for a year-long microalgae production. Scientific reports indicate that some single-cell microalgae such as Chlorella and Scenedesmus, are highly tolerant to wastewater environments and efficiently remove biogenic compounds. The aim of this study was to determine the possibility of using the effluent produced in the process of anaerobic degradation of whey as a culture medium for the multiplication of Chlorella vulgaris algae biomass and to characterise their growth efficiency and rate. The content of nitrogen and phosphorus in wastewater was sufficient for conducting an effective culture of algae. The efficiency of nitrogen removal in the flow system was 15.61 ± 1.38 mg N/dm/day.
富含有机碳、氮和磷的废水可为微藻的全年生产提供便利的碳源和营养物质。科学报告表明，一些单细胞微藻，如绿藻和栅藻，对废水环境具有很强的耐受性，并能有效地去除生物化合物。本研究旨在确定是否可以利用乳清在厌氧降解过程中产生的废水作为培养普通绿藻藻类生物量的培养基，并对其生长效率和速率进行特征描述。废水中的氮和磷含量足以进行有效的藻类培养。在流动系统中，氮的去除效率为 15.61 ± 1.38mg N/dm/day。
