| 摘 要： | 油船含油压载水大量排放入海会对海洋生态环境产生较大的危害。在研究中,通过强电离放电技术制取高浓度臭氧,应用臭氧氧化方法来深度处理含油压载水,模拟实验表明在臭氧投加浓度达到120mg/L,在较短的接触时间(2min)内,臭氧对不同浓度的含油压载水中的油去除率可达到50%以上,同时使芳香族类物质显著减少,降低含油污水的生物毒性,处理方法具有可观的应用前景。

| Abstract: | The discharge of large amount of dirty ballast water from oil tankers poses a threat to the marine ecological environment. High concentration ozone gas generated with dielectric barrier discharge technique is used to the in-depth treatment of the oil polluted ballast water. The research shows that the oil removal rates of the ballast water can reach to over 50 percent after 2 minutes oxidation by ozone when the concentration of the ozone gas load reaches up to 120 mg/L. The aromatic hydrocarbon and the biological toxicity of the treated ballast water can also be reduced obviously. The ozone oxidation technique has a considerable application prospect. |
