%X Removal efficiency of AOC in drinking water source by seven different kinds of processes composed of pre treatment,conventional treatment or advanced treatment were studied in this paper.Results showed that the pre treatment of biological ceramic had a high removal of AOC,AOC was reduced about 45% after biodegradation and 58 4% when pre ozonation preceded biological treatment;conventional treatment resulted in an about 20% limited decrease in AOC;removal of AOC was steadily about 30% becasue of the adsorption of the new active carbon and enhanced to above 50% when active carbon plus post ozonation;combined processes including conventional treatment,biological pre treatment,pre ozonation and biological active carbon had the best removal efficiency of AOC by 86%.So,ozonation,biological active carbon and biological treatment were the important ways to improve the biostability of drinking water.The optimal processes aimed at different water sources were put forwad based on this test.
