内蒙古工业大学本科毕业设计说明书摘 要本次设计内容为华北地区某市的市政给水工程，其中包括取水工程、水处理工艺、送水工程和管网布置及优化，每一部分又涵盖了主要构筑物的设计计算与该构筑物的平、剖面详图。本次设计中依据地形特点采用岸边式取水构筑物（合建式），原水通过取水泵站送至水厂后首先经配水井进入机械絮凝沉淀池处理，随后进入普通快滤池，处理后的各项水质指标基本满足要求，出水经液氯消毒后进入清水池，最后由送水泵站（半地下式）通过城市管网将处理后的出水送往各用户。本次设计中的关键是水处理工艺的确定，结合原水的各项物化指标及生活饮用水标准，最终选择机械絮凝沉淀池与普通快滤池，处理效率高，处理效果稳定。此外，取水构筑物的选择主要依据水源地的地形特点以及水量的变化情况，采用岸边式取水构筑物，送水泵站的设计核心为水泵的选择和泵房的布置，应遵循安全、合理的基本原则，同时也适当考虑经济因素，城市供水管网的布置应满足各个用户的用水要求，同时，应尽量避免不必要的浪费，合理分配主干管和其间的连接管，在满足供水要求的基础上，最大程度降低管道造价。关键词：市政给水；岸边式取水构筑物；机械絮凝池；斜管沉淀池；普通快滤池。AbstractThe design elements of a city in North Chinas municipal water supply projects, including the water works, water treatment technology, engineering and bottled water pipe network layout and optimization, covering every part of the main structure and the design of the structure, peace, Profile detail. The design based on terrain features using water-shore structures (co-Style), raw water intake pumping station sent through the water after the first wells into service by Machinery flocculation sedimentation tanks，water turbidity NTU, and then went to V-filter, and after the various water quality indicators meet the basic requirements, effluent liquid chlorine disinfection by-entered the pool, Finally, bottled water pumping station (semi-underground) through the distribution network of treated water to the consumers. The design, the key is to define the technology of water treatment, the combination of the raw water and the physical-chemical indicators of living standards for drinking water, final choice Machinery flocculation pond with General fast Filter, high efficiency, stability effect. In addition, the intake structures based mainly on the choice of water features of the terrain and contained the situation. using water-shore structures, the design of bottled water pumping station pumps core of the choice and layout of the pumping station, to be followed safety, The basic principle of reasonable, but also appropriate to consider economic factors, urban water supply pipe network layout should satisfy all users of the water requirement, but should try to avoid unnecessary wastage, rational distribution of trunk and the connecting pipe which, in meeting the demand for water, the biggest reduction in pipe cost.
