1、摘 要本设计为许昌市某区给水工程工艺设计,设计水量满足最高日供水量8.5104m3/d。设计的主要内容为:溶液池、溶解池、混合设备、絮凝池、沉淀池、滤池、消毒方法、清水池、二泵站等。根据最高日供水量及自用水量,拟定处理构筑物的设计流量,并根据确定的净水厂位置,选择适宜采用的处理构筑物,确定设计采用的处理构筑物的形式及数量。在进行构筑物的设计计算时,确定各构筑物和各主要构件的尺寸并绘制部分简图,并且绘制各构筑物的平面图、剖面图和水厂高程图及总平面布置图。设计时还需考虑到构筑物及其构件在施工上的可能性,并符合要求。同时,根据原水水质、水量、地区条件、施工条件和给水厂的运行情况,确定给水厂的处理工艺
2、流程。其工艺流程为:原水管式静态混合回转式隔板絮凝池平流式沉淀池普通快滤池液氯消毒清水池二泵站城市供水管网。关键词:混合;絮凝;沉淀;过滤;ABSTRACTThis design for the water supply engineering process design district Xuchang city, design water meet the highest water 8.5104m3/d.
