【摘要】：工業(yè)園區(qū)是我國工業(yè)化進程中重要的建設項目之一,面積之大世界罕見。園區(qū)是否能實現(xiàn)低影響開發(fā)直接關系到我國基本建設可持續(xù)發(fā)展目標的實現(xiàn)。將工業(yè)園區(qū)建設成為海綿型工業(yè)園區(qū)是建設海綿城市的主要內容之一。工業(yè)園區(qū)的低影響開發(fā)內容主要包括透水鋪裝、徑流蓄集、徑流處理、垂直綠化和雨水利用。本文從前三個方面開展相關的技術參數(shù)的研究,并以某工業(yè)園區(qū)的設計為案例,提出海綿工業(yè)園區(qū)的設計方案。主要工作及結論如下：實驗比選了混凝土透水磚、硅砂透水磚、覆膜硅砂透水磚、石子橡膠透水磚四種不同的透水鋪裝方式的孔隙率和滲透系數(shù),模擬分析相應的水文效應,結果表明：透水鋪裝適用于暴雨頻繁地區(qū)；石子橡膠透水鋪裝方式洪峰削減量最大、遲滯洪峰效果最長,分別達12%、15min。工業(yè)廠房屋頂雨水池的水質分析實驗表明：雨水蓄水池內水質秋季最差,冬季最好；冬季水質基本符合Ⅲ類水標準,春、夏、秋的水質超出V類水標準。試驗設計了一種雨水旋流分離窨井,分析了對不同粒徑懸浮物、漂浮物和油類的去除效果,結果表明：懸浮物、漂浮物、油類去除率最高的流速域為：6.3 m3/h～9.5 m3/h、 6.3m3/h～11.1m3/h、7.9m3/h～12.8m3/h,去處效果可達80%、90%、80%；相同流速下,200目和100目硅藻土溶液的去除率基本相同,低于50目硅藻土溶液。以SWMM為模擬平臺,應用本文研究的透水鋪裝、徑流蓄集、窨井分離技術及文獻提的屋頂綠化、生物滯留池技術,比選了某工業(yè)園區(qū)的低影響開發(fā)技術方案,提出了海綿型工業(yè)園區(qū)的設計方案,主要技術效果為：低影響開發(fā)技術對徑流污染物有明顯的削減效果,去除率均高于40%；在重現(xiàn)期10年的情況下,出流時間延遲30min,峰值削減29%,而在重現(xiàn)期0.5年的情況下,出流時間推遲60min,峰值削減44%。
[Abstract]:Industrial Park is one of the most important construction projects in the process of industrialization in China. Whether the park can achieve low impact development is directly related to the realization of sustainable development goal of capital construction in China. It is one of the main contents of the construction of sponge city to build an industrial park into a sponge industrial park. The low impact development of industrial park mainly includes permeable pavement, runoff accumulation, runoff treatment, vertical greening and Rain Water utilization. In this paper, the related technical parameters are studied from the first three aspects, and taking the design of a certain industrial park as an example, the design scheme of sponge industrial park is put forward. The main work and conclusions are as follows: the porosity and permeability coefficient of four different permeable paving methods, concrete permeable brick, silica sand permeable brick, coated silica sand permeable brick and stone rubber permeable brick, are compared, and the corresponding hydrological effects are simulated and analyzed. The results show that the permeable pavement is suitable for frequent heavy rain, and the stone rubber permeable pavement has the largest Hong Feng reduction and the longest hysteresis Hong Feng effect, up to 12 minutes and 15 minutes, respectively. The water quality analysis of the Rain Water pool on the roof of industrial workshop shows that the water quality in the Rain Water reservoir is the worst in autumn and the best in winter, and the water quality in winter basically accords with the class 鈪，
