Removal of Organic Matters from Drinking Water Source by Ozonecombined Processes
臭氧组合工艺去除饮用水源水中有机物的效果

In this paper the removal efficiencies of organic substances in drinking water source by ozonecombined processes composed of ozonation,biololgical process,conventional treatment and GAC adsorption as well as the different steps in this train were studied.Results indicated that preozonation enhanced the removal of organic substances by subsequent biological treatment and GAC because the ozonation of organic substances decreased the molecular size and increased biodegradability by products.Entire processes showed a good control ability of organic substances and the removal rates were 951% for UV 254,925% for DOC,984% for BDOC,858% for AOC,631% for THMFP and 891% for HAAFP.Pretreatment including preozonation and biodegradation resulted in an about 50% reduction in organic substances ,conventional treatment got different removal in different organic substances,intermediateozonation combined with GAC removed about 60% organic substances.
