【Abstract】 Biological stability of drinking water in a city is studied. The result shows that the concentration of AOC in discharged water treated by traditional process is 306.4 μg/L, exceeding the standard of biological stability in drinking water (100 μg/L). Biological treatment unit is added after coagulation precipitation in trial process, the concentration of AOC in discharged water is 49 μg/L (less than standard value 50～100 μg/ L),biological stability of drinking water is guaranteed.更多还原
