Abstract

Ballast water management is an effective measure to ensure that organisms and bacteria do not migrate with the ballast water to other areas. The International Maritime Organization adopted the International Convention on the Control and Management of Ballast Water and Ship Sediments, in 2004 which regulates issues of ballast water management. Many technologies have been researched and developed; in particular, using UV rays is the method that is evaluated with many advantages and meets the requirements of the Convention. The UV reactor in the ballast water treatment system has a very large capacity, so in the ballast water treatment system, it is often necessary to use many high-power UV lamps in one UV reactor. These high-power UV lamps consume a lot of electrical energy and are very expensive. Research on the control of UV radiation in the process of disinfecting water appropriately and effectively is necessary in order to improve the life of UV lamps, consume less electricity, and ensuring anti-bacterial duty is well conducted. This paper presents the development of a controller for a UV reactor and ballast water flow in the ballast water treatment system installed on ships. Experimental results on ships indicate the efficiency achieved by the developed UV controller.

开发压载水处理系统中的紫外线反应器控制器,以尽量减少对海洋环境的生物威胁
压舱水管理是确保生物和细菌不会随压舱水迁移到其他地区的有效措施。2004 年,国际海事组织通过了《压载水和船舶沉积物控制与管理国际公约》,对压载水管理问题做出了规定。目前已经研究和开发了许多技术,其中使用紫外线的方法被认为具有许多优点,并且符合公约的要求。压舱水处理系统中的紫外线反应器容量很大,因此在压舱水处理系统中,往往需要在一个紫外线反应器中使用许多大功率紫外线灯。这些大功率紫外线灯消耗大量电能,价格昂贵。为了提高紫外线灯的寿命、减少电能消耗并确保抗菌任务的顺利进行,有必要研究如何在水消毒过程中合理有效地控制紫外线辐射。本文介绍了船舶压载水处理系统中紫外线反应器控制器的开发情况。船上的实验结果表明了所开发的紫外线控制器的效率。

期刊介绍: The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
