微藻在CO2生物捕集及废水生态修复领域的研究进展

温室效应、水资源短缺和能源危机是21世纪人类面临的三大挑战。微藻是一种水生植物,在CO₂减排、废水生态修复及生物能源领域已成为全球研究热点。综述了微藻在CO₂生物捕集和废水生态修复的应用研究进展。微藻生物柴油现已成为全球研发热点,但研究主要集中在某个单元的最优化设计,而对各单元之间相互作用和耦合的重要性缺乏充分认知,提出了将CO₂生物捕集、废水生态修复、生物柴油制备、藻渣替代水煤浆与煤共气化的理念,这对微藻生物过程的高效全局优化和环境综合治理具有重要意义,是未来我国发展低碳经济的有效途径,并在此基础上对微藻产业规模化的未来核心研究方向进行了展望。

The Advancement of CO2 Biological Trapping and Wastewater Ecological Recovery Based on Microalgae Cultivation.

Greenhouse effect, water resource crisis and energy crisis are the three major challenges in front of human beings in the 21st century. Microalgae, as a kind of aquatic plant, have become a hot global research topic in the field of CO₂ emission reduction, wastewater ecological recovery and biological energy. The application research progress in using microalgae in the field of CO₂ biological trapping and wastewater ecological recovery is summarized. Based on microalgal biological processes research concentrating on optimum design of one unit and lacking of fully cognition toward the importance of interconnection, The conception of coupling these factors are putted forward. The new biofuel strategy is biodiesel production of high oil content microalgae coupled with wastewater treatment and flue gas, then algal residue and coal both vaporize. Efficient global optimization and environmental comprehensive control is important. To develop low carbon economy is an effective way in China, The future research emphasis and prospect of microalgae interconnection are also mentioned.
