摘要

基于生命周期方法与水足迹理论,建立了涵盖燃煤生产、运输、发电过程的煤电生命周期水足迹评价模型。以我国内蒙古自治区为研究对象,进行了煤电的水足迹评价,结果表明,内蒙古地区煤电水足迹为5.974L/(kWh),其中灰水足迹占比67.3%,蓝水足迹占比32.7%。内蒙古自治区2017年煤电产生水足迹21.85亿m~3,其中蓝水足迹7.13亿m~3,占年工业用水总量34.27%。煤电行业对水资源的巨大占用,将会影响农业等领域以及工业领域内其他行业的用水。以鄂尔多斯、锡林郭勒、呼伦贝尔为代表的大型煤电基地建设应充分考虑用水来源及煤电发展对当地水资源的影响。
        Based on the life cycle assessment and water footprint method, a life cycle water footprint assessment model for coal-fired power, including coal production, transportation and power generation, was established. Taking Inner Mongolia as the research object, the water footprint of coal-fired power was evaluated. The results showed that the water footprint of coal-fired power in Inner Mongolia was 5.974 L/(kWh), of which gray water footprint accounted for 67.3% and blue water footprint accounted for 32.7%. Also, the total annual water footprint of coal-fired power in Inner Mongolia in 2017 was 2.185 billion m~3, of which blue water footprint was 713 million m~3, accounting for 34.27% of the total industrial water consumption. The huge occupation of water resources by the coal-fired power industry would affect water use in agriculture as well as in other industries.The construction of large coal-fired power bases represented by Ordos, Xilin Gol and Hulun Buir should fully consider the influence of source of water and the impact of coal-fired power development on local water resources.
