介绍了南方某市给水厂进行深度处理升级改造的目标及工艺选择的过程,对深度处理工艺设计特点等进行了阐述。运行结果表明,对于水质季节性剧烈波动的原水,采用臭氧预处理/后臭氧-生物活性炭深度处理工艺是合理和可行的。 This paper introduces the process of upgrading and rebuilding the water supply plant in a certain city in southern China and the process selection. The characteristics of deep treatment process design are also described. Operating results show that it is reasonable and feasible to use ozone pretreatment / post-ozone-biological activated carbon for deep treatment of raw water with seasonal fluctuations in water quality.
