邢台市工业用水特征与节水效益分析计算

Industrial Water Characteristics in Xingtai City and Analytical Calculation of Water Saving Benefit

通过对邢台市工业用水和节水效益分析计算，为工业发展规划、合理高效利用水资源提供科学依据。采用邢台市2001~2012年用水量资料，对邢台市各行业用水比重、工业用水变化趋势以及万元产值净用水量进行分析。邢台市工业用水占总用水量的10．95％；工业用水量年际变化较大，工业用水量总体呈下降趋势，平均每年减少0．0056亿m3；通过对邢台市各行政区万元产值净用水量分析，各行政区之间相差较大，高用水工业万元产值用水量为12．92m3，一般工业为5．58m3。邢台市工业用水量减小而工业增加值逐年上升，主要措施是：实现不同行业间的循环用水，提高节水管理水平；严格实行建设项目水资源论证制度，提高水资源承载能力；大力推行水平衡测试制度，为全面总量控制、定额管理奠定了基础。

Analysis of industrial water and calculation of water saving benefit in Xingtai city provide scientific basis for the industrial development planning, and rational and effective utilization of water resources. Using data of water use in Xingtai city during 2001-2012, proportion of water use for each industry, industrial water changing trends and net duty of water for ten thousand Yuan output value are analyzed. Xingtai city industrial water accounts for 10.95% of the total amount of industrial water use; annual change of industrial water use is large and the overall industrial water use trends down decreasing 560,000 cubic meters annually; through analyzing net duty of water for ten thousand Yuan output value of each administrative region in Xingtai city, it is found that there is a large difference between administrative regions, water consumption of ten thou- sand Yuan output value of industry with high water use is 12.92 cubic meters, and that of general industry is 5.58 cubic meters. Industrial water use in Xingtai city is reduced and the industrial added value increases year by year. The main measures are： achieving the recycling of water be- tween different industries, and improving the management level of water saving; strictly imple- menting the system of water resources argumentation of construction project, and improving the bearing capacity of water resources; vigorously promoting the water balance test system, which lays the foundation for the total amount control and quota management.
