This study was conducted through elelctrolysis since titanium (Ti) as cathode and RuO₂-IrO₂ coating stabilized (RuO₂-IrO₂/Ti) as anode to control the cyanobacteria bloom and the remediation of water exposed to cyanobacteria bloom events. The order of influence on theoretical energy consumption of algaecide was electrode spacing > electrode voltage > electrolysis time through the orthogonal test method, considering the energy consumption of algaecide, the electrode spacing of 60 mm, electrode voltage was 30 V and electrolysis time was 12 hours were the most appropriate factors to removal cyanobacteria bloom. The strong acidic environment produced by anode enhanced the concentration of production of ·OH and other strong oxidizing substances which were the main reasons to remove cyanobacteria bloom; phosphorus and nitrogen factors causing algal blooms were also analyzed, the electrolysis reaction was conducive to the transformation of organophosphorus in cyanobacteria to DIP in water and some DIP was deposited on the cathode through electro-deposited enhanced the removal of P in water with the prolongation of electrolysis time, and meanwhile it was beneficial to reduce the total nitrogen (TN) and ammonia nitrogen (NH₃-N) in the water. Thus, elelctrolysis was an effect way to remove cyanobacteria bloom and recovery P as the concentration was higher.
