Background

With increasingly intensified eutrophication degree of fresh water and marine water and more frequent outbreak of harmful algae, the flooding of water bloom and red tide becomes a major water environment problem faced by China at present. The water quality is deteriorated due to the outbreak of algae, and the death of fishes is caused by the exhaustion of dissolved oxygen in water when the water quality is serious; microcystins generated after the microalgae are cracked can be accumulated in filter-feeding aquatic animals, so that potential risks are brought to the safety of water products; the algal toxins can not be effectively removed by the conventional drinking water treatment process and are also harmful to human bodies. Therefore, it is extremely urgent to search for a way to systematically and comprehensively remove cyanobacteria.
