北京市第九水厂二、三期工程介绍

The 2nd and 3rd Phases of Construction of the Ninth Waterworks in Beijing

北京市第九水厂二、三期工程工艺设计中选用了快速机械搅拌混合、推流式波形板水力絮凝、侧向流波形斜板沉淀、均质煤滤料过滤、构筑物密集型集团式布置等新技术及多喷口流量控制阀、快速轴流式机械搅拌器、2 5 5 0kW电压型变频器等新设备。工程运行表明所选用的新技术、新设备高效、安全、节能 ,其中多项属国内首创。

New treatment structures were adopted for the second and third phases construction of the Ninth Waterworks in Beijing,including rapid mechanical mixer, corrugated sheet plug flow hydraulic flocculation chamber, sedimentation tank with lateral corrugated plates and homogeneous coal filters which are laid out in group compactly. Also new devices were adopted. such as multi nozzle flow control valve, high speed axial mechanical agitator and voltage frequency converter of capacity 2 250 kW. The trail operation shows that these new technologies and equipments are high efficient, safety and energy saving, and some of them are advanced worldwide and first time used in this country.
