石家庄市主城区应急需水规模浅析

Emergency Water Demand Scale in the Main Urban Area of Shijiazhuang City

城市应急水源工程建设是城市供水保障体系的重要组成部分,加强常规水源和应急备用水源之间的有机结合,通过不同水源之间的互通互济和联合调配,可提高城市供水的安全性和可靠性。以石家庄市主城区为研究对象,在现状用水水平分析基础上,根据国民经济发展规划和居民生活刚性用水需求,分别采用定额指标法、人均综合用水指标法进行应急需水规模预测,综合确定石家庄市主城区应急需水规模,该成果可为应急水源工程规模的确定提供技术支撑。

The construction of urban emergency water source engineering is an important component of the urban water supply guarantee system,strengthening the organic integration between conventional water sources and emergency backup water sources.The safety and reliability of urban water supply can be improved by interconnecting and coordinating different water sources.This article takes the main urban area of Shijiazhuang City as the research object.Based on the analysis of the current water use level,according to the national economic development plan and the rigid water demand of residents,the quota index method and the per capita comprehensive water use index method are respectively used to predict the emergency water demand scale.The comprehensive determination of the emergency water demand scale in the main urban area of Shijiazhuang City can provide technical support for the determination of the emergency water source engineering scale.
