海上围隔进行羟基杀灭赤潮生物的研究

采用强电场电离H2O、O2方法,在分子层次上加工成高浓度羟基自由基(OH.)溶液,喷洒在有赤潮生物的海面上,当海水的羟基质量浓度达到0.68 mg/L时,致死洛氏角刺藻(Chaetoceros lorenzianus)等31种赤潮生物效率达到99.89%,致死细菌、弧菌效率达到100%,致死膝沟藻孢囊、多甲藻孢囊效率达到100%;赤潮生物叶绿素a含量低于检测方法低限值;剩余OH.分解成H2O和O2;尸体将分解成CO2、H2O和微量无机盐。从试验数据表明,OH.是治理赤潮有效可行的绿色新方法。实现了治理赤潮以及加工羟基过程的零污染、零废物排放、零残留物。

Study on enclosure test of treating red tide with hydroxyl radical

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.
