【摘要】：北京市水资源严重短缺,在考虑南水北调中线扩能增加供水量的条件下,到2030年水资源供求缺口仍有9~14亿m~3。南水北调东线外调水源可靠、水量充足、水质达标,向北延伸具有可行性。通过水资源供需平衡计算,确定2030年东线北延进京工程调水规模10亿m~3。基于低碳发展理念,探索在河北省文安县新建文安洼水库(库容4.2亿m~3)将汛期不调水调节为全年连续输水进京。北京境内工程布局以优水优用、一水多用为目标,现有一环输水线路(107 km)水源为优质中线水,供城市生活为主;规划二环输水线路(140 km)水源为东线北延水,供生态环境为主。以此,促进形成一环、二环分质供水,相对独立,调度灵活,运行安全及备用可靠的工程体系。
[Abstract]:There is a serious shortage of water resources in Beijing. Under the condition of increasing water supply in the middle route of South-to-North Water transfer Project, the water supply and demand gap will still be 9 ~ 1.4 billion mm3 by 2030. South-to-North Water transfer East Line external water source reliable, adequate water, water quality standards, to the north extension is feasible. Based on the calculation of water resources supply and demand balance, the water transfer scale of the project of East Route North extension to Beijing in 2030 is determined to be 1 billion mm3. Based on the concept of low-carbon development, this paper explores the construction of Wenanwa Reservoir (storage capacity of 420 million mm3) in Wenan County, Hebei Province, and adjusts the non-diversion of water in flood season to continuous water delivery to Beijing throughout the year. The layout of the project in Beijing is aimed at the optimal use of water and the multiple use of one water. The water source of a water conveyance line (107 km) is of high quality for urban life, and the water source of the second ring water conveyance line (140 km) is the eastern route of northern water ducting, which is mainly used for ecological environment. In order to promote the formation of a link, two ring water supply, relatively independent, flexible scheduling, safe operation and reliable standby engineering system.
