微藻采收技术的研究进展

Progress in microalgae harvesting technology

摘要:

微藻作为一种有巨大应用前景的生物质资源，在环境保护、废水处理和清洁能源等领域广泛应用。但是微藻采收成本过高严重限制了微藻产业的发展，因此，寻找一种经济、环保、高效的采收技术对促进微藻产业的发展具有十分重要的意义。本文分析了常用微藻采收技术的优缺点，包括离心分离、沉降、过滤、浮选和絮凝技术，重点论述絮凝技术在微藻采收方面的研究进展，以期为微藻高效、低成本采收方案的选择及其研究方向提供参考。

Abstract:

Microalgae are promising biological resource, which will play important role in environmental protection, wastewater treatment and clean energy production. However, the high-cost of the harvesting process limits its large-scale application. Thus, it is quite important to find economical, environment-friendly, and efficient microalgae harvest technologies. This paper reviewed the advantage and disadvantage of different microalgae harvesting methods, including centrifugation, sedimentation, filtration, flotation, and flocculation technology. This paper focus on research progress about flocculation technology. The main aim is hoping to provide some theorical and technological support for economic, environment-friendly, efficient harvesting technologies to promote the microalgae industry.
