微藻磁分离进展研究

Progress in Magnetic Separation of Microalgae

微藻能源是理想的可再生能源,能部分替代化石能源。然而其开发利用受微藻细胞小、浓度低导致的采收困难、采收成本高的限制。低成本、高效率地将微藻与水体有效分离是保障微藻推广利用的关键。本文分析了传统微藻分离技术存在的难点及研究趋势,讨论了国内外微藻磁分离技术研究现状及存在问题。为微藻水处理、资源回收等领域的进一步应用提供一定的基础理论研究保障。

Microalgae is an ideal renewable energy source that can partially replace fossil fuels. However, the difficulties and high cost of microalgae harvesting which caused by small cell and low concentration are the main constrains of microalgae utilization and further application. Hence, cost-effec- tive separation of microalgae from water body becomes the key issue to microalgae utilization. This paper analyzed the difficulties and research trends of traditional microalgae separation technology, discussed the current problems of microalgae magnetic separation technology, and further provided a theoretical basis for microalgae water treatment, resource recovery and its other application.
