摘　　要：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 constmdng rate constants were 0.009 3, 0.013 3 and 0.014 5 L/ gSS. h respect/vdy. The aerobic biodegradability of the mono-fluorophenols decreased in the order of 4- fluorop- henol〉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.By measuring the respiratory oxygen consumption, a study on the aerobic biodegradability of 2fluorophenol, 3 fluorophenol and 4fluorophenol was conducted using activated sludge acclimated by themselves respectively.
