- 摘要:
- 雨水是一种宝贵的淡水资源，对其加以利用能够缓解城市水资源短缺的形势，雨水资源化利用正逐渐成为生态校园建设的重要内容。在对天津市某大学校园雨水径流水质进行监测的基础上，设计了雨水资源化技术方案，以保证景观湖、绿地及道路浇洒用水为核心，以自然净化、生态处理和循环净化为关键技术，多种途径收集利用雨水。同时还着重介绍了下凹式绿地、花坛式渗滤净化技术、景观湖净化系统等雨水生态化利用技术的特点及机理。分析与计算表明，该校园的雨水资源化利用方案具有明显的经济、社会和环境效益，能够为其它校园乃至天津市的雨水利用设计提供借鉴。
- Abstract:
- Rainwater utilization can alleviate the shortage of clean drinking water in many cities. It has also became one of essential parts in the construction of an ecological campus. Based on the monitoring of the rainwater runoff, detailed analysis and research were conducted on the rainwater utilization process. The whole process was designed to guarantee the demand of landscape water body, depending on self-purification, ecological treatment and repeated-purification as the major techniques, reclaiming and utilizing rainwater in variety of ways including sunken green space, flowerbed process and landscape lake purification system. Characteristics and mechanisms of these technologies were illustrated in particular. Analysis and calculation revealed that rainwater utilization on this campus could achieve a lot of economic, social and environmental benefits, which could provide reference for other campuses and even Tianjin City.
