摘　　要：某大型水厂现有水处理工艺为常规混凝沉淀过滤处理工艺,近年来随着《生活饮用水卫生标准》(GB 5749—2006)的出台,出水标准提高,水厂需要在常规处理基础上增加原水预处理,后续工艺增加了臭氧活性炭深度处理工艺,同时滤池反冲洗废水采用UV消毒处理工艺。经改建后,水厂出水水质将大大提高,完全可以满足《生活饮用水卫生标准》(GB 5749—2006)要求。The existing water treatment process was conventional coagulation sedimentation and fil- tration treatment process in a large WTP. As the Standards for Drinking Water Quality （ GB 5749 - 2006） is implemented in recent years, the requirement for the treated water was improved. The WTP needed to increase raw water pretreatment based on the conventional treatment and add the ozone/activa- ted carbon process in the subsequent process. At the same time, UV disinfection process was used to treat the filter backwash wastewater. After the renovation, the finished water quality was significantly im- proved and could meet the requirements of the standards.
