淮水北调淮北市配水工程某大型水厂工艺设计

Process Design of a Large Water Plant in Huaibei City Water Distribution Project of Huai River Diversion Northerly Project

淮水北调淮北市配水工程某大型水厂设计供水规模30万m^(3)/d,以淮水北调工程调入水为水源,供水对象为城市工业用水(非食品、酿酒等行业),水厂设计含净水处理和排泥水处理,并预留远期预处理和深度处理用地,采用“混合+絮凝+沉淀+过滤+消毒”的常规净水处理工艺同时设^泥水处理,对絮凝沉淀瀏乍泥水进行浓缩脱水形成泥饼外运,对滤池反冲洗废水进行调节、回用。

s large-scale water plant in the Huaibei City Water Distribution Project of Huaihe Water Diversion Northerly Project has a designed water supply capacity of 300,000 m,(3)/d.The water transferred from the Huaihe Water Diversion Project is used as the water source,and the water supply object is urban industrial water(non-food,wine and other industries).The water plant design includes water purification treatment and sludge water treatment,and reserved land for long-term pretreatment and advanced treatment.The conventional water purification process of"mixing+flocculation+sedimentation+filtration+disinfection"is adopted,and the muddy water treatment is also set up.The muddy water from the flocculation sedimentation tank is concentrated and dewatered to form mud cakes;and the filter backwash wastewater is adjusted and recycled to use.
