商丘市新城区给水工程初步设计 摘要：本设计的主要任务是商丘市新城区给水工程初步设计。设计的主要内容包括：设计规模的确定、给水系统选择、取水工程设计、净水厂设计、二级泵房设计和输配水管网的计算与平差。设计书由设计资料、设计说明书和设计计算书三部分组成。 本设计的近期设计规模是32万m3/d，以地表水为水源。采用的给水系统为：原水→一泵站→网格絮凝池→斜管沉淀池→普通快滤池→清水池→二级泵房→城市管网。选用聚合铝为混凝剂，液氯为消毒剂。水厂出水水质要求达到《生活饮用水卫生规范》（2006） 。 水厂位于商丘市的东面,依河而建设的水厂，地势平坦，地面标高为60.0m，总占地面积7.0公顷，绿化面积约占25％，附属面积约占总面积的15％，内设标准化篮球场和排球场，力争创建一个清新怡人的现代化水厂。 关键词：一泵站，网格絮凝池，斜管沉淀池，普通快滤池，清水池，二级泵站,城市管网。Shangqiu City Water Supply Project preliminary design of new city Abstract: The design of the main tasks of the new city of Shangqiu City Water Supply Project preliminary design. Design of the main contents include: design size determination of water supply system selection, water engineering, water treatment plant design, two pumping stations and distribution pipe network design calculation and adjustment. Design document by the design data, design specifications and design calculation of three parts. The design of the latest design size is 320,000 m3 / d, to surface water sources. Used in water supply systems: a raw water pumping station → inclined tube grid flocculation sedimentation tank → ordinary rapid filter clean water tank → Chengshiguanwang two pumping stations. Selected polymeric aluminum coagulant, chlorine as a disinfectant. Water effluent quality required to achieve the drinking water health standards (2006). Shangqiu City water plant is located to the east, by the river, the construction of waterworks, flat, ground elevation of 60.0m, total area of ??7.0 hectares of green area accounts for about 25% subsidiary of the area accounts for about 15% of the total area, equipped with standardized basketball and volleyball courts, and strive to create a fresh and pleasant, modern waterworks. Keywords: a pumping station, the grid flocculation tank, inclined tube sedimentation tank, ordinary rapid filter, clean water tank, two pumping stations, distribution network 1. 商丘市新城区基础资料 1 1.1. 城市概况 1 1.2. 气候条件 1 1.3. 水文 1 1.4. 工程地质 2 2. 设计用水量计算 3 2.1. 综合生活用水 3 2.1.1. 综合生活用水定额 3
