“凯敏”轮压载水管理系统的科学管理初探

[摘要] 随着世界航运业的发展，船舶压载水问题给全球海洋环境和经济发展带来一定程度的威胁。压载水会把侵害性水生物带到新的环境，从而破坏新环境生物链的正常生产，甚至可能危害人类的正常生活。目前，已经成为影响海洋生态环境安全的四大危害因素之一。因此，安全而有效治理船舶压载水及其沉积物已成为国际海洋环境研究中的热点课题。首先，在查阅多方相关资料后，本文对压载水进行了综合论述，分析了压载水处理的重要性；其次，简述了几种针对压载水处理的管理方法，分析了它们的优缺点；接着，详细论述了“凯敏”轮所使用压载水处理技术，并就其处理原理进行分析。同时针对“凯敏”轮电解法处理压载水所产生的问题进行分析，并提出解决办法。

The Scientific Managment of Ballast Water Treatment System in New Activity Tanker

[Abstract] With the development of the world shipping industry, the ship ballast water problem has brought a certain degree of threat to the global marine environment and economic development. The ballast water will take the invasive aquatic organisms to the new environment, destroy the normal production of the food chain in the new environment, It could even do harm to the human normal life. At present,the ballast water has become one of the four major risk factors that affect the safety of marine ecological environment. Therefore, the safe and effective way to manage ship ballast water and sediment has become a hot topic in the international marine environmental research.Firstly，based on the references，the Paper summarizes the related Problem of ballast water，clarifies the importance. Secondly，the paper briefly introduces

several kinds of treatments of ballast water. Besides, compares the advantages and disadvantages among those treatments and the practicality of the extant methods. Lastly, the paper initially analyses the problem which might be raised by use of electrolytic method for the treatment of ballast water onboard，makes advice about the ballast water treatment system of “NEW ACTIVITY”.
