1、虹吸滤池工艺给水设计xxx（师范大学环境工程学院xx级xxx班)指导教师:xx（xxx）摘要:本次设计为虹吸滤池工艺给水工程设计，设计内容主要包括三部分，即给水处理工艺流程设计（包括虹吸滤池）、个单体构筑物的工艺设计和泵站、泵房工艺设计。根据设计资料，本次设计取水水源为地表河流水，该河流水质较好，符合Ⅱ类水源水的水质指标。本次设计所采用的净水工艺流程为：原水——混凝沉淀——过滤——消毒。混凝包括混合和絮凝两部分。混合是在静态混合器中投加聚合氯化铝，絮凝设备选用回转式隔板絮凝池，选用平流沉淀池进行沉淀
2、，过滤设备采用虹吸滤池，最后投加液氯进行消毒。水泵和泵房的设计中，给水泵选用离心泵，采用排水泵排水。水厂总占地面积，因地制宜并考虑到远期发展，水厂的工艺流程采用L型布置，流程力求简短，适当增加绿地，使水厂立面丰满。最后进行各项工艺的详细计算，并达到设计所需各项要求。关键词:水厂；水质模拟；虹吸滤池；平流沉淀池；处理工艺SiphonFilterProcessWaterSupplySystemZhangQiannan（Class181Grade07inCollegeofEnvironmentalEngi
