摘　　要：当前,能源危机和环境污染的双重压力严重制约着经济发展,开发清洁可再生型生物燃料显得尤为重要。微藻具有易繁殖、富含脂质、不与农作物争地等特点,被认为是极具前景的生物燃料,但微藻采收的高成本是藻类工业化的主要瓶颈。絮凝法是收获微藻生物质高效和优选的方法。该文简述了目前已使用的一些微藻絮凝采收方法,比较了化学絮凝、生物絮凝和物理絮凝等方法的收获效率、能耗及技术可行性,分析了各种方法的絮凝机理和影响因素,旨在为选择适宜的微藻采收方法提供参考。Currently,the development of economy is seriously restricted by the dual pressure of energy crisis and en⁃vironmental pollution,it is particularly important to develop clean and renewable biofuels.Microalgae is considered to be promising biofuels due to its easy reproduction,fat-rich,and non-competition with crops and so on.However,the high cost associated with microalgae harvesting is a major bottleneck for commercialization of algae-based indus⁃trial products.Hence,microalgae harvesting is recognized as an area that needs to be explored and developed.Addi⁃tionally,flocculation is an efficient and optimal method for harvesting microalgae biomass.This article aims to collate and present an overview of current harvesting strategies such as physical,chemical,biological,methods along with their future prospects.This review also analyzes their flocculation mechanism and influencing factors.In contrast,the use of natural polymer organic flocculants has received more attention,and future research should focus on assessing the economic feasibility on an industrial scale.This review intends to provide guidance for the high-efficiency and low-cost flocculation recovery technologies in the biofuel industry.
