摘　　要：针对某给水厂的水源为微污染水的问题,论文分析原水水质中的主要污染因子及低温低浊的现状。通过参考已运行的一期工程的工艺流程,并考虑针对低温低浊水质特点的工程措施,该项目二期工程采用处理工艺为“预臭氧+生物预处理+常规处理+臭氧生物活性炭+消毒”的方法。结果表明:该工艺充分考虑了原水特性,适用于微污染水源的大型给水厂,可保证出水水质达标。In view of the problem that the water source of the water supply plant is slightly polluted water,this paper analyzes the main pollution factors in the raw water quality and the present situation of low temperature and turbidity.By referring to the process flow of the first phase of the project that has been in operation,and considering the engineering measures for the characteristics of low temperature and low turbidity water quality,the treatment process of the second phase of the project is“pre-ozone+biological pretreatment+conventional treatment+ozone biological activated carbon+disinfection”.The results show that the process fully considers the characteristics of raw water and is suitable for large-scale water supply plants with micro-polluted sources,and the effluent quality can be guaranteed to meet the standard.
