摘　　要：针对水厂取水和净水构筑物运行中存在的问题,提出具体的改造方案,新建应急粉末活性炭投加间、机械混合池和排泥处理,并对其他净水构筑物进行了土建和设备改造。改造完成后,出厂水达到设计要求,浊度始终在1 NTU以下,夏季高藻季节出水COD Mn平均值稳定在1.2 mg/L。In view of the problems existing in the operation of water intake and purification structures in a waterworks,the specific reconstruction scheme was proposed,including the construction of emergency powder activated carbon dosing room,mechanical mixing pool and sludge discharge treatment,and the civil engineering and equipment transformation of other water purification structures.After the reconstruction,the treated water could meet the design requirements,the turbidity was stably below 1 NTU,and the average COD Mn was stable at 1.2 mg/L in the high-algae season in summer.
