摘　　要：通过设计北京奥林匹克公园中心区雨水利用系统,对雨水回收利用技术进行了大量的研究和技术攻关,在确保排水通畅的前提下,提出了"水体自然净化的雨水利用"设计新理念。将透水铺装区域、绿地、水系等各类用地统盘考虑,通过透水砖、露骨料透水混凝土、增渗设施等新型透水材料,利用透水铺装和渗滤沟内的砂砾料和增渗设施净化雨水。在收集雨水过程中,实现对水质进一步净化,使收集的水质满足灌溉、水景、回灌地下的相关标准,节省了成本,建成了高标准的公园雨水利用系统,对兑现"绿色奥运"承诺和北京的水资源的循环利用具有重要意义。In this research, the storm water reclamation system of Beijing Olympic Gommon Domain was investigated, the storm water reclamation technique was discussed, and the concept of ＂self-purification technique for storm water reclamation＂ was proposed on the premise of free drainage. By using permeable brick, exposed permeable concrete and other permeable material, pervious pavement and sand gravel in percolating ditch and other pervious facilities were introduced to purify the storm water. In the process of storm water collection, further purification was performed to reach the standards of irrigation, waterscape and groundwater recharge. This design not only saved costs but also produced a high quality storm water utilization system, which is significant for undertaking the promise of ＂Green Olympics＂ and the recycle of water resources in Beijing City.
