Abstract: The non-thermal plasma technology has the characteristics of simple operation, high treatment efficiency, low energy consumption and environmental friendliness, and has been studied and applied in algae removal in water. The mechanisms of non-thermal plasma for algae removal, different types of reactors and their application and effects of algae removal were systematically summarized based on summarizing and collating the relevant literature at home and abroad. Furthermore, the factors affecting the algae removal efficiency of non-thermal plasma technology were reviewed, and the advantages of this technology applied to algae removal were analyzed. In addition, some prospects for the development and application of this technology in algae removal were made in order to provide reference for the engineering application of non-thermal plasma on algae removal.
