10多年来,北京地区连续干旱,潮白河流域缺水形势不断发展,水源地地下水位持续下降,取水难度不断增加。受此影响,作为引潮入城工程的主要水源,潮白河水源地供水能力逐年降低,从而对工程的运行产生了很大的影响。在当前北京市地下水资源普遍严重紧缺的形势下,笔者结合引潮入城工程水源地运行管理实例,参考多年的水源井群管理经验,探讨引潮入城工程水源地供水能力的影响因素,并提出几项对策,力图通过采取科学有效的措施,克服影响供水能力的不利因素,确保水源井群的安全、稳定、高效运行,提高供水能力。
In the past 10 years, due to the continuous drought in Beijing and the continuous development of water shortage in the Chaobai River basin, the groundwater table in the water source continued to decline and the difficulty of water withdrawal increased. Affected by this, as the main source of water for the Tidal Civic Project, the water supply capacity of the Chaobai River water source has been reduced year by year, which has a great impact on the operation of the project. Under the current situation that groundwater resources are generally scarce in Beijing, combining with the operation and management of the water source project in the Tidalwater into the city and referring to the management experience of the water source wells for many years, the author discusses the influencing factors of the water supply capacity of the water source project and introduces several countermeasures , Trying to overcome the unfavorable factors affecting the water supply capacity by adopting scientific and effective measures to ensure the safe, stable and efficient operation of water source wells and to improve the water supply capacity.
