雨水回收利用系统在某博物馆中的应用--以第四届（2013年）全国绿色建筑设计竞赛方案为例

摘要

The application of rain water recycling system is expounded by taking a museum plan in the Fourth (2013) National Green Building Design Competition as an example. The project is located in Yangzhou, where rainwater is abundant and the water quality is good, the condition is appropriate as the water source of rainwater recycling system. The uses of recycled water are identified, and the water balance is calculated based on the characteristic of water usage in this program. The economic feature of the system is analyzed, the result shows 14 233.11m3 municipal water can be saved every year, so the costs can be re-covered in about 20 years. Its synergy of economic, ecological, environmental and social benefits is signifi-cantly.%以第四届(2013年)全国绿色建筑设计竞赛某博物馆方案为例，介绍雨水回收利用系统在该方案中的应用。该方案地处扬州，而此地雨水资源丰富且水质良好，适合作为雨水回收系统的水源。根据该项目用水特点，确定雨水回收的用途，并进行了水量平衡计算。此外，对该系统的经济性进行分析后，结果显示：在本方案中雨水回收利用系统每年可节约市政供水量达14233.11 m3，该系统在约20年内可以回收成本，经济、生态环境及社会综合效益显著。
