海水淡化全成本分析及其发展前景探讨——以天津北疆电厂海水淡化项目为例

摘要

Water shortage is a major environmental issue that attracts global concern. China is one of the countries with water scarce in the world. This study evaluated and analyzed the cost of desalination project in Tianjin Beijiang Power Plant. In accordance with the relevant theory and desalination cost evaluation methods, the study analyzed the components and calculated the full cost of seawater desalination, then made comparisons with other new ways of water resource use, including the South-to-North Water Diversion, reclaimed water use, rainwater usage, so as to explore the feasibility of desalination in alleviating the water crisis in Beijing and Tianjin areas.%水资源短缺是全球关注的重大环境问题，而中国是全球最为缺水的国家之一。选取天津北疆发电厂海水淡化项目进行成本实证评估与分析，进行全成本的构成分析和综合核算评估，进而与其他新型水资源利用方法（南水北调、中水回用与污水资源化、雨水利用）进行成本比较与分析，探讨其海水淡化模式应对京津地区水资源危机的可行性。
