【摘要】：近年來，隨著水資源短缺、城市內(nèi)澇頻發(fā)和初雨污染等問題日益突出，，雨水利用和排放技術(shù)工程得到越來越多的關(guān)注和應(yīng)用，特別是低影響開發(fā)技術(shù)得到了迅速的發(fā)展，我國的室外排水設(shè)計規(guī)范也越來越多地關(guān)注雨水的排放和低影響開發(fā)技術(shù)的應(yīng)用。低影響開發(fā)技術(shù)的應(yīng)用會減小匯水區(qū)域的徑流系數(shù)，改變匯水區(qū)域的集水時間，從而使雨水排放和利用系統(tǒng)與傳統(tǒng)的分流制排水系統(tǒng)相比差異甚大，故當(dāng)采用低影響開發(fā)技術(shù)時，雨水管渠設(shè)計流量及調(diào)蓄池容積的計算公式均需可能會有變化。而我國過去和現(xiàn)行的《室外排水設(shè)計規(guī)范》并未對低影響開發(fā)下雨水排放和利用系統(tǒng)的設(shè)計給出系統(tǒng)的方法，因此迫切要求對低影響開發(fā)模式下分流制雨水系統(tǒng)的管渠設(shè)計流量及調(diào)蓄池容積的計算方法開展研究。 本文對國內(nèi)外雨水利用工程情況及調(diào)蓄池容積的計算方法進行了綜述和分析，并理論分析了低影響模式下雨水管設(shè)計流量及調(diào)蓄池的容積計算方法，在此基礎(chǔ)上利用SWMM模型模擬了低影響開發(fā)技術(shù)對徑流總量、徑流峰值的削減效果及對污染物的去除效果，取得了以下研究成果： ①對不同類型分流制系統(tǒng)的雨水調(diào)蓄池進行了分析，提出了分流制下不同的雨水調(diào)蓄池系統(tǒng)，并在總結(jié)國內(nèi)外雨水調(diào)蓄池容積計算方法的基礎(chǔ)上，給出了適用于我國的雨水調(diào)蓄池容積計算程序和方法。 ②對低影響開發(fā)技術(shù)的類型進行了系統(tǒng)分析，并分別針對設(shè)有生物滯留設(shè)施、雨水滲透設(shè)施（分雨水管渠設(shè)計重現(xiàn)期P小于等于和大于雨水滲透設(shè)施設(shè)計重現(xiàn)期兩種情況）、貯留利用設(shè)施的分流制雨水排水管渠設(shè)計流量及調(diào)蓄池容積和設(shè)調(diào)蓄池的后續(xù)管渠的計算公式。 ③以重慶市某片區(qū)為對象，研究了利用暴雨徑流管理模型（SWMM模型）對應(yīng)用低影響開發(fā)技術(shù)的雨水系統(tǒng)的設(shè)計方法，對采用低影響開發(fā)技術(shù)前后的徑流及污染削減情況進行了比較，計算得出，當(dāng)設(shè)計降雨重現(xiàn)期為5a~20a時，35.07%的下凹式綠地對徑流容量的削減率為34%~42%，11.88%的滲透性鋪裝對徑流容量的削減率為23%~23.5%，28.91%的綠色屋頂對徑流容量的削減率為46.99%~47.40%；35.07%的下凹式綠地對TSS、COD、TN的去除率分別為15.3%~23%、14.06~22.9%、14.41%~28.41%；11.88%的滲透性鋪裝對TSS、COD、TN的去除率分別為23%~23.5%、20.17%~24.33%、25.2%~27.43%；28.91%的綠色屋頂對TSS、COD、TN的去除率分別為44.37%~47.93%、44.14%~47.19%、49.8%~51.48%。
[Abstract]:In recent years, with the shortage of water resources, frequent urban waterlogging and primary rain pollution and other problems, Rain Water has been paid more and more attention to and application of the technology of utilization and discharge, especially the low-impact development technology has been developed rapidly.The outdoor drainage design code of our country also pays more and more attention to Rain Water's discharge and the application of low impact development technology.The application of low-impact development technology will reduce the runoff coefficient of catchment area and change the catchment time of catchment area, thus making Rain Water's discharge and utilization system very different from the traditional distributary system and drainage system.Therefore, when the low impact development technology is adopted, the calculation formulas of the design flow rate and the volume of the storage tank may change.However, in the past and present in China, the "Outdoor drainage Design Code" has not provided a systematic method for the design of low-impact development and rainwater discharge and utilization systems.Therefore, it is urgent to study the design flow and storage tank volume of Rain Water system under low impact development mode.This paper summarizes and analyzes Rain Water's engineering situation and calculation method of storage tank volume, and theoretically analyzes the calculation method of rainwater pipe design discharge and storage tank volume under low influence mode.On this basis, the SWMM model is used to simulate the effects of low impact development technology on total runoff, runoff peak value reduction and pollutant removal, and the following research results are obtained:The main contents are as follows: (1) the Rain Water storage pool of different types of distributary system is analyzed, and the different Rain Water storage pool system under the shunt system is put forward, and on the basis of summing up the capacity calculation method of Rain Water storage pool at home and abroad,The program and method for calculating the volume of Rain Water storage tank are given.(2) the types of low-impact development techniques are systematically analyzed, and the biological detention facilities are respectively used.Rain Water percolation facility (design recurrence period P < equal to and greater than Rain Water percolation facility design recurrence period), the diversion system of storage and utilization facilities, the design flow rate and the volume and adjustment of the storage and storage tankThe calculation formula of the subsequent pipe and canal of the storage tank.Taking a certain area of Chongqing as an example, the design method of Rain Water system with low impact development technology was studied by using storm runoff management model and SWMM model.The runoff and pollution reduction before and after the use of low-impact development technology are compared and calculated.
