摘　　要：针对我国近海水域内富营养化程度加深的现状,围绕水体富营养化的核心问题,即高浓度的N和P元素去除,本工作以燃料电池反应机理与置换反应原理为依据,提出发电过程结合脱除N和P并合成MgNH_(4)PO_(4)的思路,设计了反应路线。以含N和P水体作为镁燃料电池电解质,通过镁燃料电池的离子反应将水体内正铵离子、磷酸根离子与镁离子结合生产MgNH_(4)PO_(4)产品。同时探究本实验MgNH_(4)PO_(4)的生成机理,并通过数据分析初步判断其处理海水富营养化有较好的效果且镁燃料电池工作时输出稳定,具有一定的可行性。In view of the deepening of eutrophication in China's offshore waters,the current research focused on the core issue of water eutrophication,that is,the removal of high-concentration N and P elements.Based on the fuel cell reaction mechanism and displacement reaction principle,this work proposed the idea of combining N and P removal and MgNH_(4)PO_(4) synthesis during the power generation process,and designed the reaction route.Water containing N and P was used as the electrolyte of the magnesium fuel cell,and positive ammonium ions,phosphate ions and magnesium ions in the water are combined to produce MgNH_(4)PO_(4) products through the ion reaction of the magnesium fuel cell.The formation mechanism of MgNH_(4)PO_(4) was explored,and preliminarily judge through data analysis that it had a good effect in treating seawater eutrophication,the output of magnesium fuel cells is stable when it is working,which has certain feasibility.
