【摘要】：城市水資源系統(tǒng)是大自然系統(tǒng)中的一個(gè)子系統(tǒng),令城市中雨水資源得到良好利用可達(dá)到改善區(qū)域環(huán)境的目的,提出對(duì)海綿城市建設(shè)中嵌入式雨水收集系統(tǒng)進(jìn)行設(shè)計(jì)。首先,根據(jù)收集方式的不同概括為屋面雨水收集、路面雨水收集及綠地雨水收集,通過(guò)對(duì)年雨水量的計(jì)算獲取集雨量數(shù)據(jù),利用徑流系數(shù)了解地面匯水面積、地面坡度、建筑密度分布及路面鋪砌情況,對(duì)雨水管渠進(jìn)行設(shè)計(jì)初步完成嵌入式雨水收集系統(tǒng);其次,對(duì)收集后的雨水采用初期雨水棄流和旋流分離污染物控制處理技術(shù),利用雨水徑流對(duì)污染物的沖刷規(guī)律和輸送規(guī)律對(duì)雨水中的雜質(zhì)和非點(diǎn)源污染進(jìn)行控制,再通過(guò)旋流分離器對(duì)雨水中難以分離的泥沙實(shí)現(xiàn)分離,通過(guò)以上步驟即完成了城市雨水收集系統(tǒng)的綜合設(shè)計(jì)。實(shí)驗(yàn)證明,運(yùn)用該嵌入式雨水收集系統(tǒng)可提高對(duì)雨水資源的利用率。
[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.
