摘　　要：近年来再生水已经成为北京市水资源的重要组成部分。为了保证再生水利用输水方案合理可行,安全可靠,文中以永定河再生水供水北线工程为例,首先通过大量的调研、实地踏勘,充分了解工程区间情况,完成了明渠输水和管道输水方案,并对两方案工程内容、湿地方案、工程投资、工程实施难度、水质水量保障、水环境和原有工程功能影响分析、工程管理及汛期输水保障等方面进行了详细的分析研究。经比选,虽然明渠方案具有增加沿线河道水面,改善区域生态环境的优点,但存在对北京市自来水第三水厂水源地造成水质污染风险,与区域蓄滞洪功能矛盾,汛期输水调度管理难度大,工程投资高等问题,因此推荐采用管道输水方案。本文提出的再生水明渠输水和管道输水形式的分析论证可供类似城市再生水利用输水方式的选择参考。In recent years, the reclaimed water becomes an important part of the water resources in Beijing. For ensuring the re- claimed water conveyance scheme to be reasonable, feasible, safe and reliable, both the open-channel conveyance and pipe con- veyance schemes are made through large amount of investigation, site survey for acquiring the actual situation of the project area at first by taking the Project of the North Route of Yongdinghe River Reclaimed Water Supply, and then the detailed analyses are made on both the schemes in the aspects such as the project content, wetland scheme, project investment, project implementation difficulty, guarantee of water quality and water quantity, impacts from the water environment and the original engineering func- tion, project management, guarantee of water conveyance during flood season, etc. After the comparison concerned, although the open-channel conveyance scheme has the advantages of enlarging the water area of river channel along the route and improving the regional eco-environment, the problems are to be caused therein, i.e. the risk of the pollution on the water quality within the wa- ter source for the Beijing No. 3 Water Treatment Plant, the contradiction between the project and the regional flood storage and detention function, large difficulty from the operation management of the water conveyance during flood season, high project in- vestment, thus the scheme of pipe conveyance is recommended. Both the analysis and demonstration on the mode of the open- channel reclaimed water conveyance and pipe reclaimed water conveyance can provide a reference for selecting the mode of the similar urban reclaimed water conveyance.
