摘要: 南水北调供水的重点是城市,而城市用水最大的是工业,受水区工业用水占城市总用水的65.6%.遵照朱镕基总理关于南水北调工程“先节水后调水”的指示,开展受水区工业节水的分析工作意义重大。重点对黄淮海流域以及南水北调中、东线工程受水区的工业用水、节水现状、节水潜力及节水投资与效益等进行了分析。得出了区域工业节水在全国处在相对较高水平,工业节水的重点在现有工业及乡镇工业,但节水不能完全解决工业用水增长需求等结论。Abstract: The principal goal of the transferring water projects from south to north China is to supply water requirement of cities. Most of the water supply is for industry utilizat ion that is approximately 65.6 percent of city water utilization in the received area. Therefore,it is very important to analyze industry water saving in the received areas.This paper emphasizes on analyzing industry water utilization and present situation,potential capacity,investment and benefit of water saving in Huanghe-Huaihe-Haihe watersheds and the eastern and middle lines of the projects.The results indicate that industry water saving in the received areas is better than that of the other areas in China.The industry water saving should be focused on the present industries in cities and agricultural areas.However,increase of industry water utilization could not be satisfied by water saving solely.
