某长距离输水工程近、远期输水规模相差较大,水源和三家规划水厂东西向呈“一”字型分布,经分析论证认为,当远期规模达到近期规模的2倍以上时,宜分期建设以分别满足近、远期工况的要求;为节约能源,分成3个区分别加压输水;最后通过工程投资和运营电耗方面的比较,提出了本工程的推荐方案。 Some long-distance water conveyance project near and far the scale of water diversion larger, water and the three planning water plant east-west was “a ” font distribution, the analysis shows that when the long-term scale to twice the size of the recent Should be phased construction to meet the requirements of near and long-term conditions respectively; in order to save energy, divided into three regions, respectively pressurized water; finally, through the comparison of project investment and operating power consumption, proposed the recommendation of this project Program.
