1、师范大学环境工程学院毕业论文(设计)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
2、回转式隔板絮凝池,选用平流沉淀池进行沉淀,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17师范大学环境工程学院毕业论文(设计)SiphonFilterProcessWaterSupplySystemZhangQiannan(C
