| Abstract: |
| Using strong ionization discharge, H2O and O2 are ionized and made into OH· solution of high concentration. When this solution is sprayed on sea surface with red tide and the ratio concentration of OH· in sea water attains to 0.68 mg/L, the efficiency of killing twenty nine kinds of organisms such as Chaetoceros lorenzianus in red tide attains to 99.89%. The efficiency of killing bacterium and Vibrio attains to 100%. The efficiency of killing Gonyaulax cysts and Peridinium cysts. Cysts attains to 100%; the chlorophyll-a content of organisms in red tide is lower than the lowest limit which can be tested; the saturation DO is obviously increased; the residual OH· is decomposed into H2O and O2; the bodies are decomposed into CO2, H2O and few inorganic salts. The experimental data show that strong ionization advanced oxidation OH· is an effective and feasible green method of treating red tide which realizes zero pollution, zero waste emission and aero residua during treating red tide and producing hydroxyl radicals. |
