摘　　要：长沙县某水厂现状规模为5×10^(4) m^(3)/d,采用常规水处理工艺,存在供水规模不足、水源水质恶化、出水水质较差等问题。一期改扩建工程规模10×10^(4) m^(3)/d,针对现状用地紧缺及微污染原水的特点,采用“预臭氧+ACTIFLO沉淀池+TGV滤池+消毒”组合水处理工艺,并进行集约化设计,有效解决污染原水处理困难、现有工艺滞后、工程扩建用地不足以及运行超负荷等问题。运行结果表明,出水水质优于《生活饮用水卫生标准》(GB 5749—2006),占地面积仅为国家建设标准的40%,废水循环利用后年节约耗水量137×10^(4) m^(3),工程总投资与类似项目相比节省30%左右。The current scale of a waterworks in Changsha County is 5×10^(4) m^(3)/d,adopting conventional purification technology.There are some problems such as insufficient capacity of water supply,deterioration of source water quality and poor effluent quality.The scale of the phaseⅠreconstruction and expansion project is 10×10^(4) m^(3)/d.In view of the current shortage of land and the characteristics of micro-polluted raw water,the combined purification process consisting of pre-ozonation,ACTIFLO sedimentation tank,TGV filter and disinfection was adopted and the intensive design was carried out to effectively solve the problems such as difficult treatment of the polluted raw water,the lag of the existing technology,insufficient land for project expansion and overload operation.The product water quality of the project is better than the limitations specified in Standards for Drinking Water Quality(GB 5749-2006).The footprint area is only 40%of the national construction standard,the annual water consumption saving after wastewater recycling is 137×10^(4) m^(3),and the total investment of the project is approximately 30%less than that of similar projects.
