摘　　要：在“双碳”目标背景下,碳捕捉、利用及封存(carbon capture,utilization and storage,CCUS)是燃煤电厂实现烟气脱碳的最理想策略。在CCUS技术中,微藻固碳是极具潜力的CO_(2)利用方式。微藻不仅生长速率快而且可以将CO_(2)转化为高附加值的微藻产/制品。然而,由于光能和CO_(2)利用率低,微藻固碳目前的经济可行性还达不到商业化要求,仍需进一步研究。基于国内外的相关研究,本文首先剖析了微藻悬浮液中烟气溶解、转化、被利用的过程以及光衰减现象;讨论了CO_(2)、光质及其强度等因素对微藻生长和固碳性能的影响。其次,从选育高固碳能力藻种、增强CO_(2)传质和优化光供给策略三方面综述了提高微藻CO_(2)固定效率和光合效率的方法;扼要地阐明了其中原理,以期为后续研究提供思路。最后,展望了微藻生物质的利用方向,为微藻固碳在实现我国“双碳”目标过程中的应用提供了参考。In the context of carbon peaking and carbon neutrality,carbon capture,utilization and storage(CCUS)is the most ideal strategy to achieve flue gas decarbonization in coal-fired power plants.As for CCUS technologies,microalgae-based carbon sequestration is a promising CO_(2)utilization method.Microalgae grow fast and convert CO_(2)into high value-added microalgal products/bioproducts.However,due to the low utilization of light energy and CO_(2),the current economic feasibility of microalgae-based carbon sequestration has not met the requirements of commercialization,and further research is still needed.Based on the relevant research at home and abroad,this review firstly illustrates the process of dissolution,transformation and utilization of flue gas in microalgae suspension and the phenomenon of light attenuation.Meanwhile,the effects of CO_(2),light quality and intensity on the growth and carbon sequestration performance of microalgae are discussed.Secondly,the methods to improve CO_(2)fixation efficiency and photosynthetic efficiency of microalgae are reviewed from three aspects:breeding algal species with high carbon fixation capacity,enhancing CO_(2)mass transfer and optimizing light supply strategies.The principle is briefly elucidated to provide constructive ideas for the follow-up research.Finally,the utilization direction of microalgal biomass is prospected to provide essential reference for the application of microalgae-based carbon sequestration in the process of carbon peaking and carbon neutrality in China.
