西安建筑科技大学硕士学位论文深圳市龙岗区给水规划研究专业:建筑与土木工程硕士生:王晋枫指导教师:髙湘副教授摘要随着我的不断提高和城市化进程的不断加快,城市给水事业面临着全新的挑战,城市供水的水量、水压、水质必须达到新的要求才能满足城市的发展;同时面对日益严峻的用水环境,城市的发展对城市给水事业提出了前所未有的要求。本文研究了深圳市龙岗区给水专项规划。通过对当地给水情况的实地考察, 重点做了一下工作:规划区用水量预测;水资源利用规划布局;水厂规划布局; 配水管网规划布置和管网平差计算;供水安全保障措施等。在用水量预测方面, 本论文采用分类建筑面指标法和分类用地面积指标法进行水量预测,并采用趋势法、单位人口用水标准、单位建设用地用水标准进行预测水量的校核,结合龙岗区当地的情况确定预测用水量。在水厂规划布置方面,根据规划片区地形情况, 进行区域划分,结合用水量预测结果,进行水厂规划布置。水质指标针对规划区实际情况,结合远期深圳市供水水质的目标,建议水厂出厂水水质达到《生活饮用水卫生标准》(GB5749-2006)要求,部分指标可适宜参照《深圳市生活饮用水水质目标》执行。在管网规划方面针对各分区在立足自身水量平衡的条件下,实现主干管的互联互通,并对现状管网和规划管网应用鸿业市政管网软件进行管网平差计算,以确定规划管网的管径、节点压力以及管道流速分布。为确保满足城市发展的供水需求,本论文对规划区内供水设施负荷以及管网密度负荷进行了分析论证,结果表明规划管网可满足城市发展的需求。在供水安全保障和水质保障方面,提出了原水系统安全保障措施、输配水系统安全保障措施、水质安全保障措施以确保供水的安全性。关键词:给水规划;用水量预测;水厂布局;配水管网;供水安全西安建筑科技大学硕士学位论文 The study on the planning of water supply of Shenzhen longgang district Specialty:Architecture and Civil Engineering Author: jinfeng Wang advisor: A. Professor. Xiang Gao ABSTRACT With constantly improve the level of China's economy and the accelerating process of urbanization, Urban water supply utilities facing new challenges, Urban water supply, water pressure, water quality must meet the new requirements in order to meet the development of the city, Faced with increasingly severe water environment, the planning of water supply systems needs to meet very strict demands. This paper studied on the planning of water supply in long gang district of Shenzhen city. We focus on the following work: some important question is about water demand forecasting; Utilization of water resources planning layout; Water plant layout; layout of work and work adjustment; Water security measures. In water demand forecast, two methodologies: category gross floor indicator approach and classified land area indicator approach, are used to forecast water demand of long gang district. Trend method, the unit the population water standards and the unit construction land w
