摘　　要：针对衡水市第三系地热水供热系统提出了一个有效的梯级综合应用技术方案,对运行模式进行了优化分析,并获得了最佳回灌模式.结果表明,经过优化设计,整个供热系统运转安全可靠,地热资源利用率提高了15%,回灌水温度可降至33℃,回灌率达到50.32%,可有效解决当前第三系地热资源普遍存在的综合利用程度低、尾水温度过高且直接排放等现象,带来显著的社会效益、经济效益以及环境效益.The solution of cascade use in a heating system using tertiary geothermal water was provided in Hengshui, getting the best recharge mode from the optimized analysis on the operation ways. The results show that, the whole system of heating are in safe and reliable operation after the optimized design. The utilization efficiency of geothermal resources is increased by 15%, the temperature of rejection water could be reduced to 33℃, and the recharge rate of 50.32% reached, which can effectively solve the current problems. For example, the phenomena of low level of comprehensive utilization, too high of the tail water temperature and direct discharge existed in the using of tertiary geothermal resources. Also, the significant social, economic and environmental benefits could be obtained.
