3、配水工程。根据设计原始资料中的用水量、水质、水体资料等，首先选择进行用水量计算，确定设计规模；其次确定城市给水系统的水源选择，水源位置，取水方式，输配水方式；城市净水厂方案选择与比较，净水厂扩大初步设计；城市输水管与给水管网的设计；取水工程工艺设计；二泵房工艺设计；最后编写设计说明书绘制图纸。取水工程：根据该市的地形及地理条件，将水厂建于河流中上游，靠近河流西岸北侧地形平坦处，选用岸边式统一供水方案。一级泵选用20SA-22A型水泵四台，其中一台备用。每台泵有单独的吸水管路和压水管路，管道均采用钢管，管径分别为700mm，500mm。净水工程：（1）混凝：混凝剂采用聚合氯化铝（其中Al2O3为
4、10%），采用管道静态混合器混合。往复式隔板絮凝池反应时间20min，长22m，宽16m，有效水深2.0m廊道宽度按廊道内流速不同分为4段；（2）沉淀：平流式沉淀池设两座，停留时间取2h，长108m，宽13m，有效水深3.0m，总高3.9m；（3）过滤：普通快滤池滤速10m/h，强制滤速13.3m/h，设4组滤池，双行对称布置，每组长10m，宽10m，总高3.1m，反冲洗方式采用高位水箱反冲洗；（4）消毒：消毒采用液氯消毒，加氯量4.2kg/h；（5）清水池：设两座，单座平面尺寸为50m24m，有效水深4.0m；（6）二级泵站：选用350S125型水泵六台，其中二台备用。每台泵有单独的吸水管路
5、和压水管路，管道均采用钢管，管径分别为600mm，450mm。输配水工程：从水源到水厂的输水管及从水厂到管网的配水管都选用管径为1000mm的铸铁管，配水管网布置成环状，由送水泵站统一输水。根据最高日最高时用水量分配流量并进行管网平差，进行消防校核，以符合设计规范要求。该工程的建成和投产有望能够有效解决衡水市目前存在的供水能力不足现状，较大幅度地提高该市饮用水的安全可靠性。关键词 取水工程；净水工程；输配水工程；往复式隔板絮凝池AbstractThis design is hengshui city water supply engineering design, the design, pr
