Reused water irrigation system in Beijing Olympic Common Domain (I)

北京奥林匹克公园中心区绿化灌溉系统设计,为灌溉系统、雨水利用、灌溉泵站及自动控制等多项技术的综合设计。灌溉水源为雨洪利用收集的雨水,补充水源采用再生水;选用多种节水型的灌溉设备以满足不同植物的需求,采用计算机中央灌溉控制系统实现精确灌溉的理念;灌溉水泵采用变频泵组并根据系统要求启动及调整扬程等,达到高效、节水、节能目的。

Green space irrigation system in Beijing Olympic Common Domain is a combination of several technologies, including irrigation system, reuse of rainwater, irrigation pump plant and automation system, etc. The supply water source is from rainwater collected by rain and flood utilization system, and spare supply water is taken from reused water; several kinds of water-saving irrigation devices are adopted to meet different demands of adverse plants. By applying computer central controlling system, the concept of precious irrigation is realized. The water flow and water head of irrigating pump group is variable with requirement of system by using VFD, then water and energy is saved.
