With the method of strong ionization discharge, O 2 in air and H 2O in seawater are ionized and dissociated to dissolved OH · of high concentration, and then to spay on ocean. When the dissolved OH · concentration was 0.68 mg/L, the killing efficiencies to 29 kinds of red tide organisms, such as Chaetoceros lorenzianus, reached 99.89 %, to the bacterium and vibrio 100 %, and to the Gonyaulax cysts and Prei. cysts 100 %. At the same time, the content of chlorophyll-a in red tide organisms was less than the lowest limit of test. The residual OH · radical was dissociated to H 2O and O 2 after 20 min, and the bodies of red tide organism were decomposed to CO 2, H 2O and inorganic salts. Therefore, the treatment of red tide using OH · radical is a kind of advanced oxidation technology, which realizes zero pollution, zero emission and aero residual in the process of OH · production of radicals and the treatment of red tide.
