【摘要】：城市水资源系统是大自然系统中的一个子系统,令城市中雨水资源得到良好利用可达到改善区域环境的目的,提出对海绵城市建设中嵌入式雨水收集系统进行设计。首先,根据收集方式的不同概括为屋面雨水收集、路面雨水收集及绿地雨水收集,通过对年雨水量的计算获取集雨量数据,利用径流系数了解地面汇水面积、地面坡度、建筑密度分布及路面铺砌情况,对雨水管渠进行设计初步完成嵌入式雨水收集系统;其次,对收集后的雨水采用初期雨水弃流和旋流分离污染物控制处理技术,利用雨水径流对污染物的冲刷规律和输送规律对雨水中的杂质和非点源污染进行控制,再通过旋流分离器对雨水中难以分离的泥沙实现分离,通过以上步骤即完成了城市雨水收集系统的综合设计。实验证明,运用该嵌入式雨水收集系统可提高对雨水资源的利用率。
[Abstract]:The urban water resources system is a subsystem of the nature system, which can improve the regional environment by making good use of the Rain Water resources in the city. This paper proposes the design of the embedded Rain Water collection system in the construction of sponge city. First of all, according to the different collection methods summarized as roof Rain Water collection, pavement Rain Water collection and green space Rain Water collection, through the calculation of annual rainfall to obtain rainfall collection data, using runoff coefficient to understand the surface water catchment area, ground slope, Building density distribution and pavement paving condition, the design of stormwater pipe canal is completed, and the embedded Rain Water collection system is completed. Secondly, the control and treatment technology of initial Rain Water discards and swirl separation pollutants is adopted for the collected Rain Water. The impurity and non-point source pollution in Rain Water are controlled by Rain Water runoff scour and transport law, and the sediment which is difficult to separate in Rain Water is separated by swirl separator. Through the above steps, the comprehensive design of urban Rain Water collection system is completed. Experimental results show that the use of the embedded Rain Water collection system can improve the utilization of Rain Water resources.
