The basic concepts of circular bioeconomy are reduce, reuse and recycle. Recovery of recyclable nutrients from secondary sources could play a key role in meeting the increased demands of the growing population. Wastewaters of different origin are rich in energy and nutrients sources that can be recovered and reused in a circular bioeconomy perspective. Microalgae can effectively utilize wastewater nutrients for growth and biomass production. Integration of wastewater treatment and microalgal cultivation improves the environmental impacts of the currently used wastewater treatment methods. This review provides comprehensive information on the potential of using microalgae for the recovery of carbon, nitrogen, phosphorus and other micronutrients from wastewaters. Major factors influencing large scale microalgal wastewater treatment are discussed and future research perspectives are proposed to foster the future development in this area.
循环生物经济的基本概念是减少、再利用和再循环。从二次资源中回收可回收的营养物质可以在满足不断增长的人口需求方面发挥关键作用。不同来源的废水富含能源和营养物质,可以在循环生物经济的视角下回收和再利用。微藻可以有效地利用废水中的营养物质进行生长和生物量生产。将废水处理与微藻培养相结合,可以改善目前使用的废水处理方法对环境的影响。本综述提供了关于利用微藻从废水中回收碳、氮、磷和其他微量元素的潜力的全面信息。讨论了影响大规模微藻废水处理的主要因素,并提出了未来的研究展望,以促进该领域的未来发展。
