Abstract: Microalgae is an important basis for protection of aquatic artificial breeding, furthermore it has an irreplaceable position. Algae harvesting costs remains high, so this has become one of an important factors in a serious impediment Microalgae large-scale cultivation and industrial production. This paper not only various techniques of the recent harvest microalgae, but also analyzes the advantages and disadvantages of different harvesting techniques. And the microalgae harvesting technology`s development direction should use a variety of methods of combining, in order to develop low-cost, microalgae harvesting technology and help industrial development of high efficiency.
