【摘要】：隨著經濟快速發(fā)展,環(huán)境質量受到嚴重影響,水資源保護成為環(huán)境保護的重點難點。近幾年全國各大城市在雨季頻繁內澇,雨季的強降雨,使得全國各地開啟“看海模式”,其中城市排水系統(tǒng)更是成為各大城市的關注核心點,同時因為雨污合流導致嚴重的水環(huán)境污染。本文以城市雨污分流設計為研究對象,采用理論研究、實地調查以及多學科交叉研究等分析方法,從城市排水系統(tǒng)、城市排水體制、廣州市黃埔區(qū)排水數據調查分析以及雨污分流設計實踐四大方面進行研究,總結現狀問題并提出可行策略。在城市雨污分流系統(tǒng)設計實施實踐的基礎上,給已建、在建和將建的城市雨污系統(tǒng)一個借鑒,研究成果如下:(1)城市排水系統(tǒng)主要有合流制、分流制以及混合制三種形式,就目前城市來說,雨污分流制仍然是相對理想、完善的排水體制,是最適用于新興城市、新開發(fā)區(qū)、地形條件開闊、發(fā)展空間較大的大城市。(2)城市雨污分流增強了城市對自然災害的防御能力,具備一定的社會效益;提高了污水處理速度,降低了使用成本,產生一定的經濟效益;同時通過雨水管收集雨水并將雨水排入河道。城市環(huán)衛(wèi)、綠化部門在每年旱季也能通過河道直接取水,從而有效的節(jié)約水資源,產生環(huán)境效益。(3)廣州黃埔區(qū)自然環(huán)境條件良好,地質條件穩(wěn)定,河流水系較豐富,社會環(huán)境良好,具備較好的城市雨污分流改造的地質和經濟條件,同時因為老城區(qū)的復雜,給雨污分流設計實踐帶來一定的挑戰(zhàn)。(4)通過對雨水、污水的預測及收集規(guī)劃,相關實踐案例分析等基礎條件,結合理論研究,共同指導廣州黃埔區(qū)各區(qū)塊的雨污分流改造實踐。重點研究各地塊雨污分流設計方案,以及局部細節(jié)重點設計,對管網、建筑立管等進行雨污分流設計改造。
[Abstract]:With the rapid development of economy, the environmental quality has been seriously affected, and the protection of water resources has become the key point of environmental protection. In recent years, the major cities in the country frequently waterlogged in the rainy season, and the heavy rainfall in the rainy season, In this paper, the urban drainage system has become the focus of attention of the major cities, and the combination of rain and pollution has led to serious pollution of the water environment. In this paper, the design of urban rainwater diversion is taken as the research object. With the methods of theoretical research, field investigation and multi-disciplinary cross-research, this paper studies the urban drainage system, the urban drainage system, the investigation and analysis of drainage data in Huangpu District of Guangzhou City, and the design practice of rainwater diversion. On the basis of the design and implementation of the urban rainwater distribution system, this paper gives a reference to the urban rainwater pollution system that has been built, is under construction and will be built. The research results are as follows: 1) the urban drainage system mainly has a combined flow system. There are three forms of diversion system and mixed system. At present, as far as cities are concerned, the rain pollution distribution system is still relatively ideal, and the perfect drainage system is the most suitable for emerging cities, new development zones, and broad terrain conditions. The urban rainwater diversion enhances the city's ability to defend against natural disasters, has certain social benefits, improves the speed of sewage treatment, reduces the cost of use, and produces certain economic benefits. At the same time, collecting Rain Water through rainwater pipes and draining Rain Water into watercourses. Urban sanitation and greening departments can also take water directly through river channels in the dry season of each year, thus effectively saving water resources and generating environmental benefits.) the natural environment of Huangpu District in Guangzhou is in good condition. The geological conditions are stable, the river system is relatively rich, the social environment is good, and the geological and economic conditions for the diversion and transformation of urban rain and sewage are good. At the same time, because of the complexity of the old urban areas, Through the basic conditions of Rain Water, sewage prediction and collection planning, relevant practice case analysis and other basic conditions, combined with theoretical research, To guide the reform practice of rainwater diversion in each block of Huangpu district, Guangzhou, this paper focuses on the design scheme of rainwater distribution in each plot, as well as the key design of local detail, and carries out the design and transformation of rainwater distribution for pipe network and building riser.
