摘要(Abstract)：

海水电池镁阳极腐蚀产生Mg⁽²⁺⁾,与虾池养殖废水中的NH_4(2+),与虾池养殖废水中的NH_4⁺和P形成鸟粪石,实现资源化利用.研究了磷氮物质的量比、pH值、温度对海水电池发电和鸟粪石结晶的影响.结果表明,海水电池阴极产生OH-使废水pH值稳定在10. 0左右,适合于鸟粪石结晶. 1∶1的磷氮物质的量比可促进鸟粪石结晶,NH_4+和P形成鸟粪石,实现资源化利用.研究了磷氮物质的量比、pH值、温度对海水电池发电和鸟粪石结晶的影响.结果表明,海水电池阴极产生OH-使废水pH值稳定在10. 0左右,适合于鸟粪石结晶. 1∶1的磷氮物质的量比可促进鸟粪石结晶,NH_4⁺-N和P的回收率分别为38. 12%和98. 78%.在15～35℃范围内,提高温度可以缩短回收时间.实验过程中海水电池可以产生相对稳定的电能,产电量约为21 m W.
