英文摘要：

In the industrial application of microalgae, harvesting is a technical problem, which need to be resolved urgently. Among different methods of microalgae harvesting, flocculation is one of the most common and effective methods. This paper summarized and analyzed the relevant reports on microalgae harvesting using chemical flocculation, biological flocculation and physical flocculation in recent years. The principle and operational approach of these flocculation methods were also introduced in this study. Furthermore, the advantages and disadvantages of these methods in terms of efficiency, cost and safety were also compared. The results would provide theoretical basis and technical reference for further research and application of flocculation method in microalgae harvesting.
