重庆地区某三星级绿色建筑雨水收集系统分析

Analysis on Rainwater Collecting System for a Three-Star Green Building in Chongqing

基于重庆市降雨特点,对重庆市某绿色建筑三星级项目的雨水收集系统进行了设计,根据项目实际使用情况,将雨水用于绿化灌溉、道路浇洒及试验用补水。该文详细计算了收集雨水量和雨水回用需求量,进行了用水量平衡分析;并从经济性角度出发分析了该雨水收集系统的投资回收期约为7.2年,为其他项目的雨水收集系统应用提供了借鉴。

Based on the rainfall characteristics in Chongqing, this paper designs the rainwater collecting system for a three-star green building in Chongqing. According to the actual use of the project, the rainwater is used for green irrigation, road pouring and test replenishment. After carefully calculating the rainwater amount collected and the rainwater amount needed for reuse, this paper analyzes the water balance and, based on the economic consideration, concludes that the investment recovery period of this system is about 7.2 years, providing a reference for the application of rainwater col- lecting system in other projects.
