- 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.
