城市水厂BAC/UF工艺和臭氧/BAC工艺对比

Comparison of Biological Activated Carbon/Ultra-Filtration Process and Ozone/Biological Activated Carbon Process in Urban Waterworks

通过对以臭氧/BAC和BAC/UF为深度处理工艺的两水厂进行连续监测,测定TOC、UV254、浊度、颗粒数、细菌总数、生物量、生物分类组成以及微污染物嗅味物质,对2种深度处理工艺进行比较。结果表明:BAC/UF工艺对颗粒物及微生物控制效果明显优于臭氧/BAC工艺;臭氧/BAC工艺对有机物及微污染物的去除效果优于BAC/UF工艺;臭氧/BAC工艺的生物量以及生物多样性高于BAC/UF工艺。

Comparing biological activated carbon/ultra-filtration process and ozone/biological activated carbon process by continuous monitoring two waterworks using these two processes to detect the TOC, UV254, turbidity, particle count, total number of bacteria, biomass,biological classification and taste substance of the two waterworks. The result shows that the control effect of BAC/UF process on particulate matter and microbe was better than that of ozone/BAC process;the removal efficiency of organic pollutants and micro pollutants by ozone/BAC process is better than that of BAC/UF;the biomass and biological diversity of ozone/BAC process is higher than that of BAC/UF process.
