【摘要】：随着经济快速发展,环境质量受到严重影响,水资源保护成为环境保护的重点难点。近几年全国各大城市在雨季频繁内涝,雨季的强降雨,使得全国各地开启“看海模式”,其中城市排水系统更是成为各大城市的关注核心点,同时因为雨污合流导致严重的水环境污染。本文以城市雨污分流设计为研究对象,采用理论研究、实地调查以及多学科交叉研究等分析方法,从城市排水系统、城市排水体制、广州市黄埔区排水数据调查分析以及雨污分流设计实践四大方面进行研究,总结现状问题并提出可行策略。在城市雨污分流系统设计实施实践的基础上,给已建、在建和将建的城市雨污系统一个借鉴,研究成果如下:(1)城市排水系统主要有合流制、分流制以及混合制三种形式,就目前城市来说,雨污分流制仍然是相对理想、完善的排水体制,是最适用于新兴城市、新开发区、地形条件开阔、发展空间较大的大城市。(2)城市雨污分流增强了城市对自然灾害的防御能力,具备一定的社会效益;提高了污水处理速度,降低了使用成本,产生一定的经济效益;同时通过雨水管收集雨水并将雨水排入河道。城市环卫、绿化部门在每年旱季也能通过河道直接取水,从而有效的节约水资源,产生环境效益。(3)广州黄埔区自然环境条件良好,地质条件稳定,河流水系较丰富,社会环境良好,具备较好的城市雨污分流改造的地质和经济条件,同时因为老城区的复杂,给雨污分流设计实践带来一定的挑战。(4)通过对雨水、污水的预测及收集规划,相关实践案例分析等基础条件,结合理论研究,共同指导广州黄埔区各区块的雨污分流改造实践。重点研究各地块雨污分流设计方案,以及局部细节重点设计,对管网、建筑立管等进行雨污分流设计改造。
[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.
