摘　　要：扬州第一水厂提标扩建改造工程已竣工投产,自运行以来,经历春、夏、秋、冬四个季节,原水水质呈周期性变化。夏天原水水质变差,应对高藻原水和淮河泄洪这些季节性微污染原水时,采用了强化常规水处理、预处理和深度处理组合工艺。冬天低温低浊、沉淀池出水浊度偏高时,采用了强化常规水处理和深度处理组合工艺。应对不同的原水水质,采用了不同的组合工艺,保障了供水安全,使出厂水水质满足《生活饮用水卫生标准》(GB 5749—2006)的要求。Since the Yangzhou No. 1 Waterworks was put into service after the extension, it has been operating regularly for over three years, during which the waterworks has experienced four seasons and the raw water quality has undergone periodical changes. In summer, the water quality deteriorated. To incorporate with high algae raw water and the slightly polluted raw water caused by the seasonal flood discharge in Huaihe River, a process combining intensified conventional water treatment, pretreatment, and advanced treatment was adopted. In winter, raw water was low in temperature and turbidity. When the turbidity of effluent from the sediment pool became high, advanced treatment process was employed in combination with conventional water treatment. In response to the variations in the raw water quality due to the change of water sources, different combinations of technologies were implemented in order to ensure the security of water supply and to meet the quality of the treated water with the requirements of the Standards for Drinking Water Quality （ GB 5749 - 2006 ） .
