摘　　要：浙江沿海某自来水厂一期工程制水规模6×10^(4)m^(3)/d,原水采用优质水库水,设计采用常规处理工艺预臭氧氧化、折板絮凝沉淀池、Ⅴ型滤池和综合加药间。投产5年来,水厂运行稳定,出水浊度<0.1 NTU,pH值为7.2~7.5,耗氧量<2.0 mg/L,铁、锰含量均<0.05 mg/L,总大肠杆菌和细菌总数均未检出,符合《生活饮用水卫生标准》(GB 5749—2006)的规定。High-quality reservoir water was taken as raw water for a waterworks along the coast of Zhejiang Province with capacity of the first-stage project 60 000 m^(3)/d, and the conventional treatment technology of pre-ozonation, folded-plate flocculating sedimentation tank, Ⅴ-type filter and comprehensive dosing room was designed. In the five years since it was put into operation, the waterworks had been operating stably, with turbidity of the treated water less than 0.1 NTU, pH value between 7.2 and 7.5, oxygen consumption less than 2.0 mg/L, the contents of iron and manganese less than 0.05 mg/L, and the total Escherichia coli and total bacteria not detected, which could meet the Standards for Drinking Water Quality(GB 5749—2006).
