摘要
西北地区煤炭资源丰富,但水资源极其贫乏,水环境容量相对有限。煤炭加工转化技术项目在促进区域经济发展的同时,也面临着水资源短缺的供需矛盾。针对西北地区特定资源环境背景,提出了水环境影响评价指标体系和评价标准,利用灰色关联分析方法,就空冷发电、煤炭间接液化和煤基甲醇3种具有代表性的煤炭加工转化技术项目对水环境的影响进行了评价。结论是煤炭加工转化对水环境的影响程度随地区、技术的不同会有所差异,宁夏自治区煤炭加工转化对水环境的影响程度相对较高。
Northwest China was rich in coal resources,but was very poor in water resources.The volume of the water environment was relatively limited.The coal processing and conversion technical projects can promote the area economic development and will be facing the supply and demand contradiction of water resources in shortage.According to the special resource environment background in the Northwest China,the assessment index system and the assessment standard affected to the water environment were provided.With th...
