The algaecide phycocyanobilin and the dephosphorizing agent nano lanthanum carbonate, nano lanthanum oxide or nano lanthanum hydroxide are environment-friendly preparations which have no radioactivity, explosiveness, corrosiveness and volatility, and have no toxic action on other algae, aquatic plants and aquatic animals when the blue algae is killed and the phosphorus is removed.
