摘要
北京奥林匹克公园中心区内有大量的雨洪利用工程,主要包括透水铺装地面、绿地、渗滤沟(井)、集水池、水系等,建设规模达84.7hm2,是迄今为止最大的雨洪利用示范工程。整个雨洪利用系统主要体现了先下渗、净化,再收集、回用的设计原则,通过对天然降水水质、地表径流水质、渗滤井水质和雨洪利用收集池水质的监测结果分析得出,雨洪利用系统在收集雨水的同时已经对雨水水质进行了一定的净化(蓄水池水质满足林业灌水的水质标准),减少了以往雨洪利用系统繁琐的水质净化步骤,并使得工程投资和后期管理的运行费用大大减少,值得大力推广。
There are many rainwater and flood utilization projects in the central area of Beijing Olympic Garden, for instance, pervious pavement, green, perolation ditch （well）, pool, water system, and so on. Its scope is to 84.7 hm^2, which is the biggest demonstration area of rainwater and flood utilization project in present. The design principle, reflected by the whole rainwater and flood utilization project, are percolation and purif ying. and then collecting and recycling. The Results of research about rain water, runoff water, percolation well and poll, indicates the rainwater utilization system purify the water when it collects rainwater （the water in the poll meets the forestry irrigation standard）. At the same time. it reduces investment, management and complex purifying steps, which are worth to popularize.
