摘 要
通过分析我国小区雨水回收与利用系统的类型,结合昆明市雨水收集利用的相关文件、相关标准规范,在红庙小区规划的基础上进行了雨水综合利用初步设计。对雨水收集利用工程进行了初步设计,屋面雨水总体收集起来后先进行初期雨水弃流,然后进行过滤、自然沉淀处理,主要回用于景观用水;对路面、铺地面收集的雨水进行自然沉淀处理,主要回用于绿地浇灌、道路浇洒用水。本研究针对红庙小区雨水利用现状,从工程的角度出发提出了具体的设计方案,旨在解决红庙小区的雨水收集利用问题。

ABSTRACT
Through the analysis of types of community rainwater collection and utilization system in our country, combining with the relevant documents , standards and specifications of Kunming City rainwater collection and utilization, we carried on the preliminary design on comprehensive utilization of rainwater on the basis of the HongMiao residential quarter planning. By the preliminary design on rainwater collection project, overall roof rainwater is collected after the abandoning flow of initial rainwater, and then with filter ,natural precipitation processing, it’s mainly used for landscape water in return. By natural precipitation process of the collect rainwater on the ground of pavement, it’s mainly used for green land irrigation and street flushing water in return. This study aimed at the status quo of HongMiao residential quarter rainwater utilization, put forward a specific design scheme from the perspective of project, to solve the rainwater collection utilization problem of HongMiao residential quarter.
Key words: Rainwater collection and utilization;The abandoning flow of initial rainwater;Rainwater treatment;Rainwater reuse
