【摘要】：在中国淡水资源日趋匮乏以及节能减排压力日益加剧的背景下,海水淡化和风力发电越来越受到人们的关注。文章以江苏大丰的风能海水淡化工程为例,重点从制水生命周期成本、二氧化碳排放以及知识产权市场等角度对风电海水淡化技术的环境经济效益和未来发展前景进行了分析。结果表明:(1)拟算的大丰市风电海水淡化装置的风电成本为0.75元/kW,制水成本为3.65元/m3;(2)考虑到二氧化碳的环境价值(80元/t),风电驱动的反渗透膜海水淡化法(WE-RO法)具有较为突出的环境经济效益;(3)中国的风电海水淡化技术方兴未艾,涌现出一批以风能为唯一驱动力的海水淡化技术专利。可以得出,在沿海缺水地区,风能海水淡化技术将具有较好的环境经济效益和发展前景。
[Abstract]:Under the background of the scarcity of freshwater resources and the increasing pressure of energy saving and emission reduction in China, seawater desalination and wind power generation have attracted more and more attention. This paper takes the wind and sea water desalination project in Dafeng, Jiangsu Province, as an example. Focusing on the life-cycle costs of water production, The environmental and economic benefits and future development prospects of wind power desalination technology are analyzed from the point of view of carbon dioxide emission and intellectual property market. The results show that the wind power cost of wind power desalination plant in Dafeng city is calculated by the proposed wind power desalination unit. Considering the environmental value of carbon dioxide (80 yuan / t), wind power driven reverse osmosis membrane desalination method (WE-RO method) has more outstanding environmental and economic benefits) China's wind power desalination technology is in the ascendant. A number of patents of seawater desalination technology with wind energy as the sole driving force have emerged. It can be concluded that wind desalination technology will have good environmental economic benefits and development prospects in coastal water shortage areas.
