"最近這幾十年來，由於海上貿易及交通的擴展，外來海生物的入侵問題變得更為嚴重。國際海事組織(IMO)於2004年制定『國際船舶壓艙水及沉積物控管公約』（International Convention for the Control and Management of Ships’Ballast Water andSediments，簡稱BWM）期以公法為約束力保護全球海洋環境。本產學合作計劃以目前尚未利用於海水除菌的銅銀片作為電極，置於海水中電解產生銅銀離子，並測量電解後海水中大腸桿菌、腸球菌的數量，以及導電度與銅銀離子的濃度。電解5秒後，銅銀離子所達到的殺菌效果已達到IMO於2004制訂之『國際船舶壓艙水及沉積物控管公約』中D-2的排放標準。能以此海水導電度及銅銀離子濃度，作為壓艙水處理系統中殺菌效果的參考。而未來研究應想辦法克服海水導電度對銅銀離子濃度的影響，以避免低導電度導致離子濃度無法產生符合D-2規範的殺菌效果。銅銀離子回收系統，本研究回收裝置採用電解氧化還原方式，電流通過物質而引起化學變化的過程。電解過程是在電解池中進行的，電解池是以石墨為陽極、不銹鋼或鐵片為陰極，通入電流後，銀離子則還原成金屬銀沉積於陰極上，由於滅菌後之海水銀離子濃度不高，實驗回收銀離子濃度都偏低，使得回收的量不明顯。""In recent decades, due to the expansion of maritime trade and traffic, the invasion of exotic sea creatures problems become moreserious. The International Maritime Organization (IMO) was enacted“ International Convention for the Control and Management of Ships’Ballast Water and Sediments (BWM)“ in 2004, as the binding of public law to protect the global marine environment. In industry-university cooperative project, we using sheet of copper and silver as an electrode, placed in seawater electrolysis copper and silver ions for sterilized seawater. At the same time, we measure the electrolytic solution, the number of enterococci and E. coli, as well as conductivity and concentration of copper and silver ions. Electrolysis After 5 seconds, the bactericidal effect of copper and silver ions has been reached the “International Convention for the Control and Management of Ships’Ballast Water and Sediments (BWM)” in the D-2 standards. Can this seawater conductivity of copper and silver ion concentration as a ballast water treatment system in the sterilizing effect of the reference. The Future studies should think of ways to overcome the effects of seawater conductivity of copper and silver ions concentration in order to avoid low conductivity lead ion concentration can’t produce bactericidal effect in line with D-2 specification. Copper and silver ions recovery system , in this study, recovery using electrolytic oxidation-reduction mode , current through the material and cause chemical changes in the process . Electrolysis process is carried out in an electrolytic cell , electrolysis cell with graphite as an anode, stainless steel or iron sheet as the cathode, After passing a current, silver ion is reduced to metallic silver is deposited on the cathode , sterilization of seawater silver ion concentration is not high , so that the amount recovered is not obvious ."
