- 摘要:
- 泉州市某取水工程一、二期已建成，总设计规模为10×104 m3/d，实际供水量未达到设计能力。三期工程的设计规模为20×104 m3/d，设计采用菱形取水头部分层进水+自流管+圆形取水泵房。分层取水可根据河道水位变化选择性地开启不同高程取水口，从而取到水质较好的原水。自流管采用顶管施工，避免管道施工影响城西大道交通，同时提高进水安全性。圆形取水泵房节省占地，节约投资。设置粉末活性炭投加系统，有效应对原水季节性有机微污染及突发水源污染的问题。设置应急备用水源管道，保障原水水量稳定供应。
- Abstract:
- The phase Ⅰ and Ⅱ river water intake project in Quanzhou City have been completed, with a total design scale of 10×104 m3/d, but the actual water supply has not reached the design capacity. The design scale of the phase Ⅲ project is 20×104 m3/d, and the design adopts rhombic stratified water intake head, free-flowing pipe and circular water intake pumping station. The stratified water intake selectively opened the water intake with different elevation according to the change of water level, so as to obtain raw water with better quality. The construction of the free-flowing pipe by pipe jacking avoided the influence of pipeline construction on the traffic of Chengxi Avenue and improved the safety of water intake. The circular water intake pumping station reduced the footprint area and investment. The setting of powder activated carbon dosing system effectively solved the problems of seasonal organic micro-pollution of raw water and sudden water source pollution. The emergency reserve water source pipelines was set to ensure the stable supply of raw water.
