【摘要】：针对城市内涝严重、水资源短缺、水环境恶化等水问题,讨论了海绵城市与雨水收集利用的关系,提出城市暴雨管理的一种新观点——雨水雨能联合利用(Co-use of Rain WaterRain Energy,RWRE)。以屋面雨水收集为例,给出了其水雨能联合收集利用模式,介绍了实现RWRE的雨能发电、雨水电化处理、积水助排等几项关键技术,并介绍了世界上第一座采用RWRE模式建成的雨水电站——位于金华市茂盛岩土工程有限公司厂区内的小型雨水雨能联合收集利用系统,分析了RWRE的应用前景。分析认为,相对于传统的雨水收集利用模式,RWRE具有环境友好、节能降耗、产投比高、能协同缓解城市水问题等优势,可以通过雨水管网连接和自然能互补发电两项措施分别解决RWRE雨水收集量不足和雨能品质差的问题,从而为海绵城市建设提供了一条新途径。
[Abstract]:Aiming at the water problems such as serious waterlogging, shortage of water resources and deterioration of water environment, the relationship between sponge city and Rain Water collection and utilization is discussed, and a new viewpoint of urban rainstorm management, Co-use of Rain Water Rain Energy (RWRE), is put forward. Taking roof Rain Water collection as an example, this paper gives the combined collection and utilization mode of water and rain energy, and introduces several key technologies, such as rain-energy generation, Rain Water electrochemical treatment, water drainage and so on. The paper introduces the first RWRE model in the world, which is located in the factory area of Maisheng Geotechnical Engineering Co., Ltd., Jinhua City, and introduces a small Rain Water rain energy collection and utilization system. The application prospect of RWRE is analyzed. Compared with the traditional Rain Water collection and utilization model, it has the advantages of environmental friendliness, energy saving and consumption reduction, high production / investment ratio, and synergistic relief of urban water problems. The problems of insufficient collection quantity and poor rain energy quality of RWRE Rain Water can be solved by means of connection of rainwater pipe network and complementary power generation of natural energy, which provides a new way for the construction of sponge city.
