【摘要】 河源市是以轻工业和旅游业为主的新兴城市。她连接赣、浙,是广东省经济的重要支撑和优质生态环境基地,也是粤东北地区政治、经济、文化、科技贸易中心。论文以河源市中心城区的老城区、江东区、白田区和高埔岗区为规划对象,在分析研究供水现状及其存在问题的基础上,进行规划区内的需水量预测,同时按照河源市城市总体规划和高埔岗区详细规划、《市政工程设计技术管理标准》和项目业主的要求,研究提出了包括取水工程、净水厂、给水管网和相关供电设施在内的供水系统详细规划,主要研究工作和成果如下。1、采用人均综合指标法和单位用地面积法对老城区、江东区、白田区、高埔岗区以及埔前镇等规划区域2020年需水量进行预测,预测需水量为36万m3/d2、通过对备选水源的水质质量和取水成本的对比分析,将新丰江水库作为本供水系统规划的水源,并根据现有管线的输水能力,确定需加铺两根总长为10.2公里,管径DN1500的输水管,其工程费用为5091万元。3、综合考虑新丰江水库周边地形环境条件,确定新建水厂的厂址,并确定了供水系统采用调速泵站的运行方式。4、通过工程经济分析,分别给出了近期、中期和远期的城镇供水系统的规划估算,总投资分别为12070万元、31041.7万元和27988.18万元；单位总成本分别为0.68元/m3、0.72元/m3和0.67元/m3。更多还原

【Abstract】 Heyuan, connecting Jiangxi province with Zhejiang province, is a rising city which is mainly developing light industry and tourism. She is not only an important support of economy and high-grade ecological base in Guangdong province, but also the center of politics, economy, culture, science and technology, demestic trade in the northe-east district of Guangdong province.Taking the Old City, Jiangdong District, Baitian District and Gaopugang District in Heyuan city as the planning target, the water demand in the planning area is predicted on account of analysising and researching the status and existing problems of the present water supply situation. On the basis of overall plan of Heyuan city and detailed plan of Gaopugang District, meanwhile, according to The Standards of Technical Management on Municipal Engineering Design and the project owner’s requests, the detailed plan of water supply system is proposed, including water withdraw works, water purification plants, water distribution networks and associated power supply facilitiesin in this paper. The main researches and results are as follows:1、Adopting a per capita indicator method and unit of land area method, the water demand in 2020 in planning area is predicted to 360,000 m3/d, which includes Old City, Jiangdong District, Baitian District, Gaopugang District and Puqian Town.2、Comparing with the water quality and water cost of alternative water sources, the Xinfengjiang Reservoir is chosen as the source of the water supply system planning. According to the existing water supply capacity of the pipeline, two pipes with the total length of 10.2 kilometers and the diameter of DN1500 are needed. The project cost is 50.91 million yuan. 3、By a comprehensive consideration of the environmental conditions surrounding terrain of Xinfengjiang Reservoir, the new water treatment plant site and the operating mode of using speed pumps are determined.4、Through the engineering economic analysis, the total investment of short, medium and long-term planning of urban water supply systems are 120.70 million Yuan,310.41 million Yuan and 279.88 million Yuan respectively, and the total unit cost is0.68 Yuan/m3,0.72 Yuan/m3 and 0.67 Yuan/m3 respectively.更多还原
