雨水回收利用生态工程——南京政治学院西校区项目实例研究

Ecological Engineering Project of Rainwater Recycle:A Case Study in West Campus of Nanjing Institute of Politics

为提高雨水资源利用效率,建立节约型生态校园,结合南京政治学院西校区雨水回收利用生态工程应用实例,对校区所在地的自然环境、降雨特征进行了调查和分析,并根据校区建设规划和使用需求,对西校区的水量平衡进行了计算,确定了雨水收集总量和模式,设计了雨水循环净化工艺,使回收雨水达到中水水质标准。该雨水回收利用生态工程的应用,在节约水资源的同时,既能满足校区绿化浇灌、道路及广场清洗等需要,又降低污染、改善生态环境,取得了较好的经济、环境与社会效益。

In order to improve the efficiency of rainwater utilization and build an economical and ecological campus, a survey is done about the natural environment of campus and the feature of precipitation which is based on the analysis of the ecological engineering project of rainwater utilization in west campus of Nanjing Institute of Politics. Besides, after a calculation of water balance in west campus according to the building project and the requirement of the school, the total volume and model of the rainwater collection are identified and the purification processes of rainwater recycling and structural configuration of system are designed to make the quality of recycled water come up to the reclaimed water standard. This application of ecological engineering does not only preserve water resource but also save water for campus greening and cleaning. At the same time, it can also reduce environmental pollution, improve the ecological environment, and achieve a social, economical and environmental benefit.
