雨洪利用是解决水资源短缺的一条有效途径,北京的缺水状况严峻,建筑小区的雨洪利用越来越受到重视。通过雨洪利用能够补充水体、滋养绿地、补充植被浇灌用水以及洗车等,产生很大的环境效益。文章以海淀燕保·辛店家园为例,对雨洪资源潜力进行了分析,并计算出雨水可利用量和需求量,设计了雨水收集、利用方案,通过分析得出,该雨洪利用工程正常运行后,每年可累计节约9 768 m~3水资源,这将大大减缓水资源的供需矛盾。
Rainwater utilization is an effective way to solve the shortage of water resources. The water shortage situation in Beijing is severe, and rainwater utilization in the construction area is getting more and more attention. Through the rain and flood use to be able to add water, nourish green space, replenish vegetation and irrigation water, car wash, etc., have a great environmental benefits. Taking Haibin Yanbian Xindian homeland as an example, the article analyzes the potential of rainwater resources and calculates the availability and demand of rainwater. The rainwater harvesting and utilization plan is designed. According to the analysis, the rainwater utilization project After normal operation, a total of 9,768 m ~ 3 water resources can be saved each year, which will greatly slow down the contradiction between supply and demand of water resources.
