东莞市第二、四水厂取水口迁移及输水方案探讨
|
摘要
东莞市第二、四水厂现况取水口不在新划定的一级水源保护地,且东江流域近年来严重的咸潮上溯对原水水质产生不利的影响,为保障第二、四水厂的原水水质安全,需将取水口进行迁移。针对东莞市第二、四水厂取水口迁移工程取水及输水方案,从水源保护地的划分、河床及地形因素、上下游构筑物和水闸排站的影响等因素切入,探讨研究了取水口位置、取水构筑物形式、输水管线路由、提升泵房型式及位置。
The current intake location of No. 2 and No. 4 Waterworks in Dongguan City is not in the newly designated primary water source protection site, and the serious saline tide upstream in Dongjiang River Basin in recent years has an impact on the quality of raw water. In order to ensure the safety of raw water quality of No. 2 and No. 4 Waterworks, the water intake location is required to be transferred. In this paper, the water intake location and water conveyance schemes of No.2 and No.4 Waterworks in Dongguan City are discussed. The location of intake, the form of the intake structure, the route of water conveyance pipeline, the type, and location of lifting pump house are determined by analyzing the division of water source protection sites, river bed, and topographic factors, the influence of upstream and downstream structures and sluice drainage stations.
