In this study, 42 kinds of organic pollutants in 11 categories were qualitative identificated in drinking
water, in which esters and alkanes contained most species accounting for 31.82% and 29.55%. And peak
areas of these two categories organic pollutants occupied 20% of total peak areas. Furthermore, xylene,
dimethyl phthalate and di-n-butyl phthalate (DBP), three priority pollutants in China, were detected.
By comparing of three adsorbents, finding that activated carbon has high removal rate as 70.35% to
total peak a rea of organic pollutants, and quartz sand reduces organic pollutants species more effectively.
Quartz sand can remove heterocyclics, halogenated hydrocarbons, benzenes and acids absolutely, and
phthalates, hydrocarbons, phenols, alcohols and aldehydes preferably too. To priority pollutants, both
activated carbon and quartz sand show favorable removal characteristics. Considering of respective
advantages of activated carbon and quartz sand, we can exploit activated carbon - quartz sand combined
processes to remove organic pollutants in drinking water.
