利用微藻固定CO_2实现碳减排的研究进展

Recent progress in fixation of CO_2 with microalgae for carbon emission reduction

CO2减排是目前社会经济发展所面临的重大环境问题之一,如何高效、绿色地进行减排已成为各国科研工作者关注与研究的热点。利用微藻技术进行减排符合碳循环规律,显示出很好的应用前景。本文结合笔者近年在利用微藻技术进行碳减排方面的研究工作,从固定CO2的微藻选育、微藻的培养、微藻减排在光生物反应器方面的开发以及CO2减排与污水深度处理及高价值生物质生产的耦合等4个方面对近些年来国内外在利用微藻技术实现CO2减排方面的研究情况进行了归纳与评述,并对前景进行了展望。

The reduction of carbon dioxide emission was now one of the barriers to be overcome for the sustainable development.Therefore,to fix CO2 with high efficientcy and environmentally friendly had become the hot research field.It met natural carbon cycle by using microalgae to fix CO2.This paper reviews the recent progress in reduction of CO2 emission with microalgae.Breeding of the microalgae,the microalgae cultivation,development of photobioreactor for reduction of carbon dioxide emission by microalgae,and wastewater treatment coupling with reducing CO2 emission were highlighted in this review.Finally,perspectives of the microalgae technique were also discussed.
