摘要:

污水处理过程中会排放大量CO2,占全社会碳排放总量的1%~2%。微藻具有生长速度快、环境适应性强、固碳效率高、成本低等优点,故微藻技术被认为是目前污水处理中最环保、安全、可持续的CO2生物固存方式。微藻废水处理技术是一种很有前景且具有成本效益的方法,既可以用于CO2的生物固定,也可以用于废水的处理与修复。基于当前研究现状,综述了微藻技术在不同体积分数CO2曝气条件下减污降碳的效能,分析了影响微藻碳固定效率的因素并介绍了微藻技术的强化措施,探讨了单一微藻技术和菌藻共生技术减污降碳的机制,同时展望了未来需重点关注的研究方向,为实现“碳中和”目标及该集成技术的规模化发展打下基础。

Abstract:

A large amount of CO2 is emitted during the sewage treatment process, accounting for 1% to 2% of the total carbon emission of the whole society. Microalgae have the advantages of fast growth, strong environmental adaptability, high carbon sequestration efficiency, and low cost. Therefore, microalgae technology is considered to be the most environmentally friendly, safe, and sustainable CO2 biological sequestration method in sewage treatment. Microalgae wastewater treatment technology is a promising and cost-effective method for both biological fixation of CO2 and wastewater treatment and remediation. Based on the current research status, this paper reviewed the effectiveness of microalgae technology in reducing pollution and carbon dioxide under different volume fractions of CO2 aeration conditions, analyzed the factors affecting the carbon fixation efficiency of microalgae and introduced the enhancement measures of microalgae technology. The mechanisms of microalgae technology and bacterial-algae symbiosis technology in reducing pollution and carbon emissions were also discussed, while the research directions that needed to be focused on in the future were outlined to lay the foundation for achieving the goal of “carbon neutrality” and the large-scale development of this integrated technology.

Key words: microalgae, wastewater treatment, carbon fixation, pollution reduction and carbon reduction mechanism, carbon neutralization
