By measuring the respiratory oxygen consumption, a study on the aerobic biodegradability of 2-fluorophenol, 3-fluorophenol and 4-fluorophenol was conducted using activated sludge acclimated by themselves respectively. The experimental results showed that bio-oxidation ratios of 2-fluorophenol, 3- fluorophenol and 4- fluorophenol were 25.30%, 35.28% and 36. 60% respectively, and the oxygen consuming rate constants were 0.009 3, 0.0133 and 0.0145 L/gSS· h respectively. The aerobic biodegradability of the mono-fluorophenols decreased in the order of 4- fluorophenol＞3 - fluorophenol ＞2 - fluorophenol, resulting mainly from the different octanol/water partition coefficient and the different steric parameter of the fluorophenols which can affect the penetration of fluorophenol into cell membrane.
