The rapid development of agriculture has led to a large amount of wastewater, which poses a great threat to environmental safety. Microalgae, with diverse species, nutritional modes and cellular status, can adapt well in agricultural wastewater and absorb nutrients and remove pollutants effectively. Besides, after treatment of agricultural wastewater, the accumulated biomass of microalgae has broad applications, such as fertilizer and animal feed. This paper reviewed the current progresses and further perspectives of microalgae-based agricultural wastewater treatment. The characteristics of agricultural wastewater have been firstly introduced; Then the microalgal strains, cultivation modes, cellular status, contaminant metabolism, cultivation systems and biomass applications of microalgae for wastewater treatment have been summarized; At last, the bottlenecks in the development of the microalgae treatment methods, as well as recommendations for optimizing the adaptability of microalgae to wastewater in terms of wastewater pretreatment, microalgae breeding, and microalgae-bacterial symbiosis systems were discussed. This review would provide references for the future developments of microalgae-based agricultural wastewater treatment.
农业的快速发展导致了大量废水的产生，这对环境安全构成了极大的威胁。微藻具有多样的物种、营养模式和细胞状态，能够很好地适应农业废水，并有效地吸收养分和去除污染物。此外，经过农业废水处理后，积累的微藻生物质具有广泛的应用，如肥料和动物饲料。本文综述了基于微藻的农业废水处理的最新进展和未来展望。首先介绍了农业废水的特点；然后总结了微藻处理农业废水的藻种、培养方式、细胞状态、污染物代谢、培养系统和生物质应用；最后，讨论了微藻处理方法发展的瓶颈，以及针对废水预处理、微藻养殖和微藻-细菌共生系统优化微藻对废水适应性的建议。本文的综述为基于微藻的农业废水处理的未来发展提供了参考。
