摘要
以某江水为原水,研究某市自来水深度处理工艺(陶粒滤池、混凝、沉淀、过滤、臭氧氧化、活性炭滤池)各单元对有机污染物的去除效果,对水样的TOC、UV254、CODMn和AOC进行了分析.结果表明,陶粒滤池对TOC、UV254、CODMn和AOC的去除率分别是25.4%、29%、21.6%和54%,有效地减轻了后续单元的负担;臭氧-活性炭技术对TOC、UV254、CODMn和AOC的去除率分别是39.3%、60.8%、49.8%、77.8%,因此,组合工艺能确保饮用水的优质安全性.
In this paper, it was investigated the effects of each advanced treatment techniques including the ceramic filter, coagulation, sedimentation, filtration, ozonation and GAC filter of drinking-water originated from river water on removal effect of organic pollutants in a city, and the TOC, UV254, CODMn and AOC of the water sample were analyzed. The results showed that the removal rate of TOC, UV254, CODMn and AOC were 25.4%, 29%, 21.6% and 54% respectively by ceramic fitter, so it reduced effectively loading of the subsequent process. 39.3%, 60.8%, 49.8% and 77.8% of TOC, UV254, CODMn and AOC were removed respectively by ozonation combined GAC filtration technique, so this combined technique could assure good safety of drinking water.
