城市大型给水工程系统迁建设计

Design of System Relocation and Reconstruction of Urban Large Scale Water Supply Project

在环保督察背景下,城市饮用水水源保护问题凸显。以铜陵为例,介绍城市大型取水口、对应水厂系统迁建设计案例。铜陵市三水厂横港取水口水源保护区内存在多座码头,结合铜陵市长江岸线规划、现状供水布局及存在问题,将横港取水口、三水厂整体迁建至下游新民取水口附近,设计规模为30万m^3/d,同步建设配套给水管道,将原三水厂改造为加压泵站,工程建成后逐步关停现状一、二水厂,形成更加科学合理的供水系统。

Under the background of environmental inspection, the problem of urban drinking water source protection is prominent. Taking Tongling as an example, the paper introduces the design case of system relocation and reconstruction of large-scale urban water intake and WTP. There are several docks in the water source protection area of Henggang water intake of the No.3 WTP. Combining riverfront planning of the Yangtze River in Tongling City, current water supply distribution and existing problems, Henggang water intake and the No.3 WTP are moved to the vicinity of Xinmin water intake downstream. The design scale is 300 000 m^3/d. Synchronously, water supply pipelines are constructed, and the former No.3 WTP is transformed into a boosting pumping station. The No.1 and No.2 WTPs will be closed down gradually after the completion of the project. Finally, a more scientific and reasonable water supply system will be formed.
