摘要
山西万家寨引黄入晋工程是国家重点建设工程,山西是国家能源重化工基地,水资源缺乏,地下水超采严重,制约了当地人民生活和经济的发展,引黄工程是解决山西省城市人民生活及工业水资源紧缺问题的根本举措.需水预测是确定工程规模的重要依据,为了确定引黄工程的规模及其经济效益,分别于不同年份对太原供水区进行了三次需水预测研究.由于影响需水预测的因素众多,致使三次需水预测值有所不同,重点分析了工业用水定额的变化对需水预测的影响.结果表明,工业结构、生产工艺、设备、规模和工序对万元产值取水量和复用率等工业用水定额影响较大,而工业用水定额的变化将引起需水量的变化.
Wanjiazhai Diversion Project from Yellow River to Shanxi Province is a national key project. Shanxi is a national energy source and heavy chemistry base. The local people＇s life and economic development are restricted by shortage of water resources and seriously over withdrawing groundwater. The problems of water resources shortage for people＇s life and industry can be solved by Wanjiazhai Diversion Project from Yellow River. Water demand prediction is an important base for determining project scale. In order to determine the scale and economic benefits, three times of water demand prediction for Taiyuan water supply area are carried out in different periods. Three times total water demand predicting results are different due to many influence factors. The impact of changing industry water quota on industry water demand prediction is mainly analyzed. The results show that industry structure, processing technique, equipment, scale and working procedure bring great influence on water quota, such as water consumption per unit production value, reuse rate and etc. The change of water quota causes the difference of water demand amount.
