【摘要】：在西北地区水资源短缺、水环境恶化的背景下，城市对水资源的索求规模不断加大，凸显建设水资源集约型使用的生态城市的迫切性，本文以西北部特定案例城市一陕西省西咸新区沣东新城的给水工程、雨水工程、污水工程及再生水专项规划为案例，对城市建设中给水管网建设、雨水管网建设及雨水生态利用、污水管网建设、污水资源再生利用工程优化设计等方面做了详细的调查与研究，提出了基于生态城市建设的给排水管网及污水再生利用系统的优化方案。本论文针对案例城市对地下水的不合理开懫，以及给水管网干管的布置问题等，并结合目前案例城市给水工程的建设进度提出合理化的矫正方案；建议案例城市以低影响开发建设理念为导引，在城市建设过程中根据城市雨洪控制及生态建设的需要，保证生态型排水系统的优先建设。针对案例城市在雨水专项规划的编制过程中设计平台相对落后的问题，提出引进最新数字排水平台（Digital WaterDrainage System, DWDS)优化雨水管网系统，以确保案例城市雨水管网抵御极端洪漠灾害的水平显著提高。同时，建议懫用DWDS对案例城市在不同暴雨强度状况下城市积水情况进行了模拟，模拟结果可供城市管理部门针对不同强度的洪n灾害及时安排适当的预案。本论文借鉴国内缺水城市（北京、天津）再生水利用的工程实践和管理经验，应用于沣东新城的再生利用工程的规划和建设，，指出本案例城市再生水专项规划过程中大用户用水量调查工作缺项，且管网布置中没有充分考虑市政景观用水的实际需求，提出了关于再生水水源合理选用的创新思考；在污水管网的建设方面，提出污水处理厂布局方案的调整意见及污水管道管材调整意见。同时，提出加强市政设施的宣传的必要性。论文提出了市政管线综合方面的市政管道管位移出机动车道的优化方案，并提出尽快建立案例城市地下管网地理信息系统（GIS)，以提高市政给排水管网及排水S站设施的运行维护水平。
[Abstract]:Under the background of the shortage of water resources and the deterioration of water environment in Northwest China, the demand scale of water resources in cities is increasing, which highlights the urgency of building ecological cities with intensive use of water resources. This paper takes the water supply project, Rain Water project, sewage project and reclaimed water special planning of Fengdong New Town in Xixian New District, Shaanxi Province, as a case study, to construct the water supply pipe network in the construction of the city. The construction of rainwater pipe network and the ecological utilization of Rain Water, the construction of sewage pipe network, and the optimal design of sewage resource recycling project were investigated and studied in detail. The optimization scheme of water supply and drainage network and wastewater reuse system based on ecological city construction is put forward. This paper aims at the unreasonable opening of groundwater in the case city and the arrangement of the main pipe of the water supply pipe network, and puts forward the reasonable correction scheme combining with the current case of the construction progress of the urban water supply project. It is suggested that the case city should be guided by the concept of low-impact development and construction, according to the needs of urban rainwater control and ecological construction in the process of urban construction. To ensure the priority construction of ecological drainage system. The design platform is relatively backward in the preparation process of rainwater special planning in case cities. This paper presents the introduction of the latest digital drainage platform, Digital WaterDrainage system (DWDS), to optimize the rainwater pipe network system. In order to ensure the case of urban rainwater network to resist extreme flood and desert disaster level significantly improved. At the same time, it is suggested to use DWDS to simulate the urban water accumulation under different rainstorm intensity. The simulation results can be used for urban management departments to arrange appropriate plans for different intensity of flood disaster. This paper draws lessons from the engineering practice and management experience of water shortage cities (Beijing, Tianjin) in China. It is applied to the planning and construction of recycling project in Dongdong New City, and it is pointed out that the water consumption investigation of large users in the special planning process of urban reclaimed water in this case is short of items. Moreover, the actual demand of municipal landscape water is not fully considered in the arrangement of pipe network, and the innovative thinking about rational selection of reclaimed water source is put forward. In the construction of sewage pipe network, the adjustment of the layout of sewage treatment plant and the adjustment of sewage pipe material are put forward at the same time. Put forward the necessity of strengthening the propaganda of municipal facilities. The paper puts forward the optimization scheme of the displacement of municipal pipeline pipe out of the motorway in the comprehensive aspect of municipal pipeline. In order to improve the operation and maintenance level of municipal water supply and sewerage network and S station facilities, a case study of urban underground pipe network geographic information system (GIS) is put forward in order to improve the operation and maintenance level of municipal water supply and drainage network.
