摘要
针对羟基自由基(·OH)法处理船舶压载水过程中可能对压载舱造成腐蚀情况进行研究。在最大羟基处理浓度2.5 mg/L条件下作用压载舱常用低碳钢、不锈钢及非金属材料,检测处理前后压舱水对压载舱材料的腐蚀影响。结果表明羟基法处理压载水系统在高效杀灭外来有害生物的过程中,对压载舱金属与非金属并不具有明显的腐蚀增强,这一结果满足IMO的技术要求。羟基法在快速处理船舶压载水的同时对于压载舱壁金属腐蚀而言是安全的。该研究结果对日后压载舱的防腐设计以及压载水处理装置在船舶上的推广应用具有重要的意义。
The thesis presents the study of the situation that hydroxyl radical （ · OH） may cause the corrosion of bal- last tank material in the process of ballast water treatment. Under the highest using concentration of hydroxyl radical, the materials, such as low-carbon steel, stainless steel, and Non-metallic, are commonly used in the ballast tank to e- valuate the corrosion influence that ballast water makes on the materials of ballast tank in the pre-and post-treatment testing. The result showed that the corrosion effect of the hydroxyl radical on the metal and non-metal materials does not increase obviously when used in the system of ballast water treatment to effectively kill the exotic pests, which meets the requirements of IMO. It is safe for ballast tank wall metal to utilize the hydroxyl radical in the ballast water treatment. The study result holds a great significance for the anti-corrosion design of the ballast tank and the populari- zation as well as the application of this ballast water treatment system on board.
